How to acidify soil for indoor plants

Soil for indoor plants

All of us, fans of home gardening, replant our plants about once a year.
And, of course, in the age of the Internet, everyone, before transplanting a flower, finds information about what soil is suitable for it. So what do we read: “you need to take such and such an amount of turf soil, such and such a quantity of leaf soil, a certain amount of peat, etc.” With peat, everything seems to be clear; you can buy it at any flower shop. Where can I get leaf, turf or humus?

Very hardworking summer residents can prepare it in their summer cottages. Making turf and leaf soil, vermicompost is not very difficult, you just need time and desire. This will take, however, at least 1.5 - 2 years. Well, what about those who don’t have a personal plot? Of course, buy it at a flower shop or garden center. There are a lot of substrates being sold now. But it happens that a plant, in seemingly suitable soil, develops poorly, and sometimes simply dies. Why? Of course, there may be different reasons, but one of them is a bad substrate. To be honest, there are still unscrupulous manufacturers of soil mixtures. A friend of mine who loves violets lost all of her transplanted Saintpaulias. Only later did she realize that the substrate reeked of ammonia, the flowers were simply burnt.

Hence the advice - buy soil mixtures only from trusted companies. This is already half the success.

For some plants, special mixtures with acidity and composition suitable for this flower are sold. There are substrates for azaleas, palms, dracaenas, cacti, orchids, saintpaulias, etc. If not, buy a universal primer.

But universal soil is not suitable for every plant. For example, cyperus requires dense soil that retains water well, while dieffenbachia requires loose soil that dries well and is slightly acidic. But in principle, a universal soil mixture will suit both, if you change it a little.

Based on universal soil, you can create a soil mixture suitable for a specific plant. Various components can be either purchased in stores or assembled yourself, for example, in a forest or park.

The first thing plants react to is soil acidity. For example, an azalea will never grow well in soil with a pH of 6 - 7; it needs acidic soil.

What components increase soil acidity?

Stores usually sell high-moor peat (pH 4-5). It is loose and light, but there are few minerals in it. Peat retains water well and may not dry out for a long time, but after drying, it is difficult to wet it, the water sits on top and is not absorbed. It is not worth adding a lot of it to the soil mixture.

Coniferous land

It can be collected in a coniferous, preferably pine, forest or park. To do this, rake off the top 5 - 7 cm, where the needles have not yet rotted, and collect soil about 10 cm deep. This will be well-rotted needles, light and loose. It can be added to the soil when transplanting azaleas and anthuriums; it is especially good for heathers and hydrangeas.

heather land

If you live in a region where heathers grow, then you can easily stock up on heather soil (pH 5) yourself. You can pick it up in heather thickets. It can also be used to acidify a universal substrate.

pine bark

Having collected and crushed pine bark from the forest, it must be disinfected. Adding pine bark to the soil mixture makes it breathable, loose and increases acidity.

Sphagnum moss

Can be purchased at garden centers. It is primarily used in substrates for orchids. But you can add it to your regular soil mixture. Sphagnum moss (pH 4) will loosen the soil well, absorb excess moisture when the plant is overwatered, and enrich the soil with nutrients. In addition, it has high antiseptic qualities, so it is often used for rooting cuttings; it can be used for sowing seeds, for example, large strelitzia seeds, which take a long time to germinate, and in a regular seedling substrate they can easily be over-moistened or dried out. Before adding sphagnum moss to the soil, it must be chopped with scissors. Suitable for adding even to a ready-made substrate for Saintpaulias, azaleas, and anthuriums.

How to make the soil mixture loose, light and dry well.

This soil is suitable for most indoor plants. Particularly relevant when transplanting succulents, cacti, amaryllis, bromiliaceae, gesneriaceae, etc.

The easiest way is to add sand . But under no circumstances should it be used for construction purposes, since due to its small structure, it will only clog the ground. It is better if it is coarse river sand. By adding a large amount of sand, you reduce the nutritional value of the soil mixture. Ideally, its part should not exceed one fifth of the total composition.

Perlite will help improve soil breathability . You can buy it both in garden stores and construction markets. Perlite, which is used in construction, usually has a finer fraction, so, of course, it is better to purchase garden grade perlite. Perlite is an expanded rock of volcanic origin. Before adding it to the mixture, it is advisable to rinse it with running water, pouring it into a sieve, in order to get rid of small particles and dust.

Vermiculite can be purchased at flower shops and garden centers. In addition to the fact that it makes the soil air and water permeable, it also has a good ability to absorb water and then release it. Therefore, if vermiculite is present in the soil mixture, it is more difficult to overwater the plant, which is good. Vermiculite grains are an expanded clay mineral; they not only improve the structure of the soil, but also enrich it with minerals.

Coconut fiber is usually sold in compressed briquettes, which before use need to be filled with water for half an hour to an hour, then squeezed out and dried. When added, the soil becomes light and breathable.

For plants that require an alkaline reaction, charcoal . This is ordinary coal from a fire; it needs to be crushed a little and washed in running water. Adding coal reduces soil acidity. In addition, it is a good antiseptic. Charcoal can be used as drainage by pouring it into the bottom of the pot. If you are rooting a cutting in water, add a small piece of coal, it will prevent rotting.

How to increase soil nutrition.

Vermicompost

This ideal microbiological fertilizer can be purchased at garden centers. The microorganisms that are present in it populate the soil, healing it, improving its structure, saturating it with microelements and nutrients. But you can’t grow flowers in it alone; it is added to soil mixtures at the rate of one part of vermicompost and four to five parts of soil.

How to acidify the soil

To grow plants, you need soil of a certain acidity. Most people like neutral or slightly acidic. But there are a number of plants that grow better and bloom more beautifully in acidic soil. What is soil acidity? What needs to be done to make it more sour?

Tips for soil acidification

It is better to acidify the base under hydrangeas using alum or sulfuric acid.
It is recommended to acidify the soil under blueberries with acids, that is, by watering the bush.
The azalea base is acidified with phosphoric acid.
Most crops acidify the soil through watering. This is a convenient method and the least labor-intensive.
Acidify the base once every two months.
Flowers are acidified during flowering and budding.
It is recommended to acidify the soil with organic substances in spring or autumn.
Carefully read the instructions for the mixtures, take into account the nuances before depositing funds. Otherwise, the soil can become very acidic.

Soil acidity level

The concept of soil acidity is associated with its ability to exhibit the properties of acids. The pH indicator used to determine acidity is actual acidity. The settled solution of mineral soils is measured in a ratio with water as 1:2.5, for peat soils as 1:25. Acidity is measured on a scale from 0 to 14. The bottom 0 is acid, the top 14 is alkali. In the center of the scale is the number 7 - neutral acidity. The range from 5.5 to 6.5 corresponds to weak soil acidity. 7.5-8.5 – slightly alkaline.

All soils according to their acidity level are divided into:

Strongly acidic
Subacid
Neutral
Slightly alkaline
Alkaline

Most plants prefer to grow in soils of medium and neutral acidity. But there are a number of plants that require highly acidic soil for normal development and abundant flowering.

Determination of acidity level

The acidity of the soil can be determined accurately and “by eye”. To obtain an accurate pH value, contact a soil science laboratory with soil samples. For a fee, specialists will conduct research and determine the acidity value to the nearest tenth.

But usually such precision is not needed for growing domestic crops. Therefore, the approximate value can be determined in several ways:

In gardening stores you can buy a special device to measure the acidity level of the soil. It comes with instructions, following which you can easily determine its exact meaning.
Using the litmus test you heard about in school. Dissolve a handful of earth in water, stir thoroughly and let it settle. Place litmus paper in the solution and observe the color change. Yellow indicates neutral acidity, red indicates acidic acidity, and blue indicates alkaline acidity. Concentration is directly related to color intensity. The more intense it is, the higher the concentration.
If you don’t have a research kit and litmus test, which is quite likely, you can use “improvised means.” You need acetic acid and soda. Take a handful of earth and divide it into two piles. They pour acetic acid on one and watch the reaction. If it begins to hiss and blow bubbles, then the soil is alkaline. If soda added to the soil causes the same reaction, then the soil is acidic.

The water with which flowers and plants are constantly watered also has its own acidity value. Typically, the acidity of tap water is from 6.5 to 8.5. This is alkaline water. It leads to a change from an acidic reaction to an alkaline one. Therefore, to grow some crops, the soil needs to be acidified.

To prevent water from increasing the alkaline reaction, you must first pass it through a filter.

This is possible when growing indoor plants or garden crops that occupy small areas. When watering large areas, it is too expensive to water with filtered water.

Is it possible to water hydrangea with citric acid and vinegar?

Slightly acidic and moderately acidic soil is best suited for growing plants . The acidity level of the soil affects the flowering of hydrangeas. So, if the pH is maintained within 5.5 units, the bush will bloom profusely and as richly as possible. If the indicators are below this norm, the natural pink color will change to blue. At a pH level of 5.5–6.5, the petals will turn purple. If the acidity level exceeds 6.5 units, the inflorescences will acquire a rich red hue.

Before you start changing the acid balance of the soil, you need to check the pH level . This can be done by adding a small amount of 9% vinegar to the soil. If the soil is too acidic, a characteristic foam forms on the surface. In this case, it can be slightly deoxidized with slaked lime. To do this in the fall, you need to loosen the area around the plant and evenly sprinkle 300 g of lime per 1 m².

You can also check the soil balance using litmus paper. If the soil acidity level is acceptable (pH 5.5), it can be maintained by watering the plant with a solution of citric acid or vinegar . Methods for soil acidification are described in detail below.

How to acidify the soil

Grows best in acidic soils:

The soil acidity indicator for them should be in the pH range of 4.5-5.8. Methods for increasing acidity depend on the mechanical composition of the soil:

If it is light and loose, you need to add a lot of organic matter: compost, cow manure, sphagnum moss. During the process of decay of these substances, the acidity level increases slightly. To reduce significantly, you need to apply a lot of fertilizers.
But for heavy clay soils, the use of this method will lead to a further decrease in acidity (alkalinization). It is best to use sulfur here. Water entering the soil reacts, turning it into sulfuric acid. But the process is long. For an area of 9 square meters, 1 kg of sulfur is needed to reduce the level by 2.5 units. And the process itself will last at least a year.

Soil acidification methods:

You can use colloidal sulfur. Applying 4 g per 10 liters of soil will be sufficient for flowers that prefer acidic soils. But filling an apartment with flowerpots with flowers planted in such soil is unsafe for its residents. When it reacts with water, it releases hydrogen sulfide, which is very unpleasant and very harmful to health.
To increase soil acidity faster, add iron sulfate or aluminum sulfate. It will reduce the pH by one in two weeks. To do this, it is enough to apply 1 kg per area of 15 square meters. m.
To acidify the soil, urea, ammonium chloride, potassium salts and other substances containing ammonia are used. Calcium and potassium nitrates should not be added. They increase the pH value.
From available means, use 9% vinegar or malic acid. A half-liter bottle of vinegar is poured into 5 liters of water and the soil around the plant is spilled. But the use of vinegar is undesirable for the soil, because it destroys all fungi and bacteria, including beneficial ones. Sulfuric acid can be obtained in diluted form by draining the electrolyte from the battery.

The soil with the desired acidity level can be prepared in the fall. To do this, fall leaves, peat, and sand are placed in special piles. Water and shovel several times over the summer.

More information can be found in the video:

Acidification of soil under various plants:

The soil under young azaleas, hydrangeas and heathers is acidified during the growth of leaves and the appearance of buds twice a month.
Under old azalea bushes - once a week. After they fade, carry out the procedure again. The acidity of the soil for them is pH 5.5.
For roses, chrysanthemums and primroses, it is enough to acidify 1-2 times a year. They like soil with a pH of 6.5.
Dieffenbachia and ferns can be acidified once a year. They prefer soil pH 6.8-7.

When regularly acidifying the soil, you need to constantly check the pH level. It may happen that it will become too low and no vegetation will want to grow there. In this case, you need to add lime or dolomite flour.

What to do if the soil is acidified?

To neutralize the base (deoxidize), it is limed and calcium is added. These are the cheapest ways. In addition, calcium improves the physical properties of soil and stimulates the development of microorganisms.

For liming the base use:

chalk;
limestone;
dolomite flour;
peat and stove ash, but the ash does not act so strongly.

Sometimes waste from cement factories is used, but in this case they act with caution. You can acidify the base very strongly using this method, or you risk damaging the roots of the seedlings, which will lead to their death.

Ground limestone is also used. It is important to consider how finely it is crushed. The smaller the particles, the faster the soil will be neutralized.

Soil for indoor plants

What is the most important component for any plant, both in the wild and in home cultivation? Of course, this is the soil. Soil is the nutrition of plants and, of course, not a single plant can live without soil.

As diverse as the plant world is, so is the environment in which they grow, including the composition of the soil. One of the most important tasks of a gardener is to choose the right soil mixture for each plant. You can buy ready-made mixtures and, often, this is justified, but it is much more interesting to make the soil yourself. Don’t forget about the complaints about store-bought soil, which have become increasingly common lately:

Soil contamination (fungus, mold, nematode)
The composition of the soil does not correspond to what was declared (a large amount of peat, many fractions that are not soil - chips, knots, etc.)

[!] When using a ready-made soil mixture, always disinfect it - pour the soil onto a baking sheet and leave for about 20 minutes. in the oven at the highest temperature or freeze the soil at a temperature of -5 ° C or lower for 24 hours.

Of course, all of the above is quite rare in purchased mixtures, but if you end up with poor-quality soil, you can practically say goodbye to the plant.

So, how to make your own soil mixture and what components are needed for this:

Leaf soil is soil formed in places where fallen leaves rot, light and loose. Leaf soil is slightly acidic (pH 5-6). The structure is light, airy, the composition contains minor inclusions of not completely rotten leaves. Main application – soil mixtures for plants with delicate root systems (begonia, gloxinia, cyclamen)

Turf land is highly nutritious land harvested from pastures and meadows sown with forage grasses. There is a division into heavy earth (which contains a large amount of clay) and light earth (which contains a large amount of sand). To prepare such soil, layers of turf about 10 cm high are cut, then they are laid in layers and a little manure is placed between them. During the year, the soil matures and is then used in floriculture. It is not necessary to wait for the turf soil to ripen - you can use meadow soil immediately.

Humus soil is the soil with the highest nutrient content. It is obtained as a result of the decomposition of manure: light compounds are formed from the manure of small cattle, the manure of cows and bulls produces heavier humus. Humus soil is very rich in microelements and also contains a large amount of nitrogen. The technology for preparing humus soil is as follows: in a greenhouse or greenhouse in early spring, a hole is dug into which manure is placed; the manure is sprinkled with ordinary soil on top of which the plants are planted for seedlings. In the fall, both manure and soil are taken out of the greenhouse and kept in the open air until frost begins, after which the humus soil is ready for use.

Peat soil , on the contrary, is not highly nutritious, but, due to its high looseness and porosity, is indispensable as an additive to heavy soils. In addition, peat soil is highly acidic and is widely used in soil mixtures for plants that prefer acidic soil. Peat soil is prepared from swamp or meadow peat: the peat is extracted, cut into layers, the layers are sprinkled with lime and manure and kept for 2-3 years.

Coniferous soil , as the name implies, is land obtained in a coniferous forest and consisting of soil and rotted needles of coniferous trees. The main properties of coniferous soil are increased looseness and acidity; there are few nutrients in such soil. Coniferous soil is perfect as an additive to the main soil for plants that love soil with high acidity. In addition, not completely rotten needles, cones and small branches can be used in a substrate for orchids.

[!] If the soil contains coniferous soil, the plant will not get sick with fungal diseases and chlorosis, thanks to the disinfecting properties of pine needles.

Charcoal is used both as a component of soil mixtures and as drainage. Coal can also be used as a medicinal preparation - crushed coal is sprinkled on rotten roots and fleshy stems, such as cacti and other succulents (coal has a disinfecting effect and prevents further rotting). Coal is able to fight harmful substances even when it is part of the soil mixture, so a small addition of coal is recommended for the soil of any plants. The best charcoal for plants is obtained by burning birch or aspen firewood and then grinding it.

Coconut fiber is an organic substrate made from coconut husk fibers. Coconut fiber is a soil material unique in its properties: the fiber practically does not decompose (due to the high ligin content), does not cake and does not settle. By adding coconut fiber to the soil, you can do without additional drainage.

Determining soil pH at home
How to increase soil acidity

The growth and development of a plant depends on its correct location and soil. But not every soil is naturally optimal, and plant requirements can vary significantly. Here the soil acidity index (PH, acid-base balance) plays an important role. Some plants thrive exclusively or best in soils with an acidic pH. For example, hydrangeas, heathers, Ericas, rhododendron, garden blueberries, etc. Others prefer alkaline ones. But what if the soil at home is unsuitable? In this article we will tell you how to increase the acidity of the soil at home.

What can replace vinegar?

There are several options for replacing vinegar:

Organic	leaf compost; rotted sawdust and pine litter; peat moss (sphagnum); manure (fresh only).	1. Acidification occurs slowly. 2. The effect remains for a long time. 3. Maintains soil looseness, feeding it with additional minerals.
Minerals	ammonium sulfate; ammonium nitrate; ferrous sulfate; potassium sulfate; colloidal sulfur.	1. Significantly increases acidity in a short time. 2. Chemical compounds are used with caution, as they can cause the opposite effect.
Green manure	oats; lupine; soy; mustard; rape.	1. Planting such plants near hydrangeas maintains soil acidity.

Determining soil pH at home

The soil pH value gives us information about whether the soil reaction is acidic, neutral or alkaline (calcareous). At pH 7, the reaction of the soil solution is neutral, below 7 it is acidic, and above it it is alkaline.

By nature, acidic soils are found almost exclusively in pristine nature reserves. Garden soil usually needs to be acidified. We recommend using a soil sample to determine the actual pH value before taking action. This is quite easy to do at home.

The easiest way (Option One) is to use litmus paper. You also need testing soil, which you can get at a depth of about ten centimeters. Place this soil in a bucket, crumble it and remove any foreign objects. Take distilled water and combine it with crushed soil in a 1:1 ratio. Using litmus paper, determine the pH value of the soil based on the color.

Now just insert the sticks into the soil tester, in about a minute you will be able to read the result.

Another option is to buy soil testers. For example, the MP-330 soil acidity and moisture meter (it can be ordered in the online store). You need land for testing. Prepare it as in the first option. Now simply insert the tip of the tester into the soil. And in about a minute you will be able to see the result.

Also pay attention to wild plants in your garden. They will be able to give you a good idea of different soils. For example, dandelions, strawberries and plantain grow in acidic soil, while chicory prefers alkaline soil.

Litmus paper at home

To make litmus paper, we only need indicator substances that can change their color in the presence of acids and alkalis. And also printer paper and water. As natural indicators, you can take red cabbage, black currants, blueberries, blackberries, and chokeberries. These plants contain a dye (anthocyanin); It is he who is responsible for sensitivity to pH.

You should cut the cabbage into pieces and add a small amount of distilled (or clean) water to it. Then bring the resulting solution to a boil and simmer for about half an hour. If you use berries, chop them first.

As soon as the prepared broth has cooled, dip the printer paper cut into pieces into it (for 5-7 minutes). The paper should take on a lilac hue. Then take it out and dry it. That's all. Do-it-yourself litmus paper is ready.

Do a soil test. If the sap retains its purple color, the soil is neutral. If the color changes to pink, the soil becomes acidic, the sap turns green or blue, and the soil is alkaline.

Using tests

Use smart test indicators for the acidity of garden soil and potting soil for indoor plants. You can buy them at garden centers. In the package of this mini-lab you will find three measuring sticks and detailed instructions.

How is the pH level determined?

There are several options for determining the acidity level of your soil:

Laboratory method

The first level of determination can be attributed to laboratory methods. If you want to get accurate data on your pH level and will not spare some money for it. Then you need to contact special laboratories.

These laboratories are called soil science laboratories. Specialists will take the necessary samples from your site, using this material they will be able to conduct a multifaceted study and give you accurate results of the acidity level throughout the entire territory of the land.

At home

The second option is to determine the acidity level at home. But using this method you will not be able to determine the exact acidity level of your soil. This method will help you save money and roughly determine your acidity level. In order to determine the level, you need to do the following:

Litmus paper method

You will need litmus paper and a soil solution. The solution should be settled and well mixed. To determine the acidity level, you need to dip litmus paper into this solution and watch how the paper changes color.

If the paper has a blue tint, then the soil is alkaline. If a red color begins to appear on the paper, then your soil is at a predominant acid level. If a yellow-green tint appears on the table paper, then we can safely say that in your soil the two environments are equal and the soil is a neutral environment for plants.

You can also roughly determine the level of acidity and alkalinity, then you should look at the contrast of the color that appears on litmus paper. For example, the brighter the red color, the higher the acidity level of your soil. Also with alkaline pH.

Using specialized tests

For the next method, we will need special tests, which can be purchased at many gardening stores. This method is the most accurate of all home tests. You can find out everything you need to carry out the test in the test instructions.

Method from scrap materials

The last method, but no less effective. To carry out the test, we don’t have to do anything complicated, nor do we have to buy anything. Since almost everyone has all the necessary things in their home. For the test we need soda and acetic acid.

This method will not cause you any difficulties. To determine the environment, you will also need to take some soil from your site. Divide it into two parts, pour a little vinegar into one of them, and add a pinch of soda to the other and watch the reaction. If the soil into which you poured vinegar begins to bubble and hiss, it means that an alkaline environment prevails in the soil. Also, if the reaction begins to appear in contact with soda, it means that an acidic environment predominates in the earth.

Determine the pH level of water

If you do not want to do any research, then this method is suitable for you. To do this, you need to find out what the pH level of your water is. You don't need anything for this. Well, besides, what kind of water do you water your land with?

If you water your soil with piped water, then most likely your soil is alkaline. Since the pipeline uses alkali to disinfect water. In this case, your soil needs to increase its acidity level a little.

It is best to water the soil with filtered water, since after such water your soil will be as close as possible to a neutral environment. But this watering method is considered very expensive, since it will be necessary to water a large number of plants and this will require a lot of filtered water.

For those who are not particularly versed in the pH indicator, we will now tell you a little. The pH level ranges from 0 to 14 points. The higher the pH level, the more alkaline the environment. Also in reverse order. For example and better understanding, acetic acid has a pH of 0, and household products have a pH of 14.

How to increase soil acidity

Increasing acidity with special means

Sulfuric acid or colloidal sulfur. For 1 liter of water, use 1 drop of concentrated acid. This solution is enough for you to acidify 1 square meter of area;
Electrolytes of acid batteries. Proportion: 30 ml of electrolyte per 10 liters of water (based on 1 sq. m).

Increasing acidity with household products

There are many ways to acidify garden soil. For the sake of the environment, we recommend avoiding the use of chemicals. It is best to resort to suitable home remedies that are not only available at home but also found in nature.

It takes patience to lower the pH value over a long period of time and naturally. This process is relatively complex and can be slow and over a longer period of time. The first thing you need to do is do without lime fertilizers and lime water for irrigation. Home remedies that can make the soil acidic include coffee grounds, grape residues, conifer needles and bark, forest soil where evergreen trees grow, oak leaves, various compost mixtures or mulch, etc.

Coffee in the garden

Coffee grounds are an excellent tool that can be found in almost every housewife. It can increase the acidity of the soil and thus lower the pH units in a very natural way. This is a valuable fertilizer, especially for heather plants. You can use coffee grounds either in their pure form or as a component with particles of coniferous bark or pine needles. Coffee contains many important nutrients. First of all, the kit contains potassium, phosphorus and nitrogen in noticeable quantities. How to use? Work the dried coffee grounds shallow into the soil.

The second option is to use purchased acidic peat. And the third is to use coniferous soil taken from the forest directly under the conifers. This method is especially suitable for longer-term results, since the decomposition process of organic materials takes quite a long time. To acidify large areas, it is better to use acidic humus from chopped coniferous trees.

Mulch

Mulch is also a good means of acidification. It not only protects the soil around the plants from dehydration, but also from the growth of weeds. May also affect soil texture by lowering pH. As mulch, use a two to three centimeter thick layer of chopped wood from various coniferous species, needles, bark, sawdust, oak leaves or grass trimmings. Grass clippings should be slightly dry. Renew the mulch layer after about two years.

What kind of soil does hydrangea like?

The flower prefers fertile clay areas with slightly acidic or moderately acidic soil. The most suitable acidity level for the plant is 5.5 pH. Land brought from the place where coniferous trees grow is ideal.

The following types of soil are absolutely unsuitable:

sandy - due to a lack of micronutrients;
heavy loamy - has the ability to retain moisture for a long time, has a tendency to become waterlogged;
alkaline.

It is advisable that the beds receive good sunlight in the first half of the day, as a lack of lighting leads to a decrease in the abundance of flowering.

During the growth period, beneficial nutrients included in the soil composition gradually pass to the plant. This causes a decrease in soil acidity. Acidifying the soil for hydrangea will help correct the situation.
