How to properly plant and grow a flower in open ground
The herbaceous peony Raspberry Sundae is unpretentious to growing conditions. How well it will take root after planting and how soon it will begin to bloom largely depends on the correctness of the procedure.
Planting with root cuttings
The root division method or root cuttings is the most common method of propagating peonies. The procedure is quite simple and boils down to separating sprouts with single buds and their own roots from the root system of the mother bush.
Note! Adult peony bushes aged 3-5 years are the easiest to tolerate the division procedure.
What time does boarding take place?
The procedure for separating cuttings is carried out at the very end of August or at the beginning of September. Later dates are undesirable, since the plant will not have time to adapt to the new location and may die from the first frosts. In spring, the buds actively grow, so a spring transplant will greatly harm the mother bush.
Selecting a location
For the heat-loving peony Raspberry Sandae, it is advisable to choose a sunny area with well-drained soil. The acidity of the soil at the site where the plant is planted should be neutral.
How to prepare the soil and flower for planting
If the soil in the selected location is not loose and light enough, then river sand is added to it. To saturate the soil with nutrients, it is recommended to add peat or humus. The above-ground part of the division to be transplanted is almost completely cut off, and the root sections are dipped in wood ash.
Step by step landing procedure
Planting Raspberry Sunday is carried out in compliance with the rules that apply to all herbaceous peonies. You must proceed as follows:
Dig a hole 2 shovels deep and 50-60cm wide. The bottom is well drained with fine crushed stone. Fill the hole with a fertile soil mixture consisting of equal amounts of peat, humus, turf soil and sand. In the center of the filled hole, make a small hole with your hands, in the center of which place the root cutting. Sprinkle the roots of the cuttings with soil and compact it with your hands.
At the same time, it is important that the buds do not rise above the soil level above 3 cm. After planting is completed, the bush is carefully watered and the space around it is mulched with sawdust
After planting is completed, the bush is carefully watered and the space around it is mulched with sawdust.
Planting by seeds
Sowing peonies with seeds is quite a troublesome task, since the seed material has a low germination rate. It will be possible to evaluate the result only after 5 years, when the new plant comes into force and begins to fully bloom. This method of reproduction is used for the purpose of selection.
Note! Seedlings of a pollinated plant often sprout into seedlings that have lost their varietal qualities.
Reproduction methods
Peony Karl Rosenfeld can be propagated in two ways:
- Dividing the bush.
- Seeds.
The second method is quite labor-intensive, and flowering can only be expected in the 4th-5th year, and there is no guarantee that the varietal characteristics will be preserved.
Dividing the bush is the simplest and most effective propagation method. Flowering can be observed already from the second year, after planting. It is recommended to divide an adult bush at the end of August. Each part must contain at least three buds, from which flower stalks and an intact tuber will appear. To protect the cut site, it is treated with ash or brilliant green.
Preparation of planting material
Both seeds and cuttings can be used as planting material. But there is an unreasonable amount of trouble with the seeds, and such a plant will bloom only in five years. Therefore, the best option is to plant cuttings. An adult bush, the age of which varies from 8 to 10 years, needs to be divided into parts along with the roots. Each such part is a finished piece. You need to make sure that there are no more than 3-5 buds on it. Since the roots are damaged by division, they will not be able to provide nutrition to a larger number of buds, and as a result, the bush will develop poorly, be sick and look unsightly.
The length of the roots should be about 15–17 cm, the excess should be cut off. To treat cuts, you should make a mixture of wood ash and any fungicide. After application, it will protect the roots from various unpleasant diseases and also prevent rotting. The cuttings prepared in this way can be planted in open ground.

Planting and care
For successful cultivation and full flowering, the lactiferous peony Karl Rosenfeld requires the fulfillment of certain conditions:
- Illumination - you need to choose an open place and make sure that there is access to the sun's rays, but protection from drafts and strong winds is important.
- Soil - loamy or sandy loam soils are ideal. It is worth considering that flowers will appear earlier on sandy substrates, but their decorative qualities will be worse.
- Humidity - the main thing is to ensure good drainage and avoid stagnation of water. In soils prone to waterlogging, when planting in lowlands, the roots will most likely begin to rot.
Peonies are planted by Karl Rosenfeld in the last days of August or the very beginning of September. Planting dates directly depend on the weather conditions of the growing region. In cold climates, peonies are planted in the third ten days of August, in the middle zone - in early September, and in the south - in the first ten days of October.
Before planting, the tubers are kept in a solution of potassium permanganate, then the existing sections are treated with ash.
Seedlings must be selected that are strong and without external damage. The tubers should be quite dense. You need to make sure that there are at least four buds, then flowering will be early. Long roots are cut to approximately 15 cm.
Algorithm for planting herbaceous peony Karl Rosenfeld:
- Make a hole measuring 50x50 cm.
- At the bottom there is a drainage layer and nutrient soil.
- Compost, ash and superphosphate are added to poor soil.
- The roots of the tuber are straightened and distributed along the bottom of the hole.
- Next, the plantings are covered with earth, each layer must be compacted.
- Then water and mulch the soil.
- If there are several bushes, maintain a distance of 1 m between them.
- The flower bud is buried 4-5 cm.
Important! The herbaceous peony is not suitable for placement in flowerpots or in an apartment due to its considerable size.

- April - fertilizing with nitrogen;
- during the formation of buds - organic fertilizers;

Protection from diseases and pests
The main enemy of peonies is the ant. These insects live in huge colonies and parasitize plants, sucking the juice from them. Ants especially like the buds with their sweet nectar. Insects are also dangerous as carriers of various diseases. You can fight ants using repellents.
A colony of ants can destroy even strong peony bushes
Peony Karl Rosenfeld is resistant to many diseases if the plantings are not thickened and the watering regime is maintained. If these rules are not followed, the following ailments can be found on plants:
- Gray rot - leaves and stems suddenly wither, buds turn black and do not develop. The petals dry out at the edges and turn brown. The peak incidence occurs in the spring. Infected parts of the plant are removed and burned, and the entire bush is treated with a fungicide.
Gray rot most often appears when plantings are very dense - Cladosporiosis - manifests itself in the form of brown or purple spots on peony leaves. Over time, these spots increase in size until the entire surface becomes affected. On the back of the leaf you can see a smoky coating of spores. Overwinters on fallen leaves. Copper preparations help well against cladosporiosis.
Cladosporiosis overwinters on plant debris, which is why it is so important to promptly clear the soil of debris.
