How yellow lilacs multiply
To propagate the yellow lilac Primrose, vegetative methods are used - separation of shoots and cuttings. The method of sowing seeds is not suitable, it will not preserve varietal characteristics.
Overgrowth is a very effective and easy way. Reproduction is carried out in the fall. To do this, cut off the root, departing from the growth of 15-20 cm.
Important! The lilac bush must be rooted.
A well-sharpened and disinfected secateurs are used. The seedling is placed in a groove in a new location, separate from the mother bush. The yellow lilac of the Prime Rose variety is moved to a permanent place after 1-2 years. It is recommended to select in advance the bush you like for reproduction.
Cutting is the second effective way to propagate a unique plant on the site. Cut the cuttings after the lilac has faded. The plant must be an adult, at least 5-8 years old. Shoots for grafting are cut from annual shoots of medium length and not lignified. It is important that the internodes are short.
With a well-sharpened garden knife, cuttings are cut in the evening or in the morning (without an active sun). 2-4 buds are left on each. The lower leaves are removed, the upper ones are shortened. The future seedlings are placed for 18 hours in the Epin-Extra solution, then the lower cut is powdered with Kornevin and planted in the mother plant (greenhouse).
There are no big differences from the planting process of ordinary varieties for Primrose. It is necessary to comply with the conditions for the choice of timing, soil and place, to correctly plant. Further care will strengthen the seedling and make it possible to grow a strong flowering bush.
When to plant
The best time to plant the common Primrose lilac is the end of summer. The end of August or the beginning of September is the most optimal time. If you hold an event in spring or autumn, then the Primrose seedling does not take root well and hardly grows during the first year of life.
Site selection and soil preparation
According to the description and reviews of gardeners, Primrose lilac grows well in an open, sunny place. It tolerates partial shade well. The only condition is good wind protection.
The variety prefers light, fertile, neutral soil. If the soil on the site is acidic, then liming or other measures to reduce acidity need to be carried out. They also take measures in advance to increase the fertility of the soil - they dig up, select weeds and garbage, apply fertilizers.
Then they begin to prepare the planting holes. A distance of 1.5 m is maintained between the pits, regardless of how the plants are planted - in a group or singly. Only when creating a dense hedge can the distance between the bushes be reduced to 1 m.
The walls of each pit are made vertical. Dimensions - a cube with sides of 50 cm. This is subject to a good degree of fertility. On poor lands, a hole is dug 2 times more in order to add a nutritious soil mixture when planting. An additive is prepared from 20 kg of humus (compost), 300 g of wood ash, 30 g of superphosphate.

- Before planting, be sure to inspect the root system of the seedling. All injured, dried or broken roots are removed. The rest are shortened to 30 cm.
- The bottom of the pit is covered with a good layer of drainage from expanded clay, crushed stone or broken brick. A layer of nutrient mixture is poured on top and a mound is formed. A seedling is placed on the top of the mound, the roots are carefully straightened.
- The pit is filled with soil mixture, slightly compacted and watered.
Important! The root collar is left 30-40 cm above the soil surface.
After the moisture is absorbed, the near-stem circle of yellow lilac is mulched with peat or humus with a layer of 5-7 cm.
Features of growing yellow lilac
The Primrose variety is capable of growing even a novice gardener. Bushes will need to provide watering, nutrition, pruning, and attention. This time will take a little, since the culture is hardy and unpretentious.
The first 2 years, the seedlings are watered 2 times a week, then the amount is reduced. The main focus is on watering yellow lilacs in the summer months. It should be regular and abundant. Do not allow the soil to dry out. One plant needs 2.5-3 buckets of water. After watering, loosening is recommended to improve air access to the roots.

Features of the formation of bushes
The yellow variety has features that dictate the rules for the formation and pruning of a bush. You need to cut the plant in early spring, until sap flow begins in the shoots. At this time, dry, diseased and weakened branches are removed. It is very important to cut inward to provide the yellow lilac decorative effect. The inflorescences of the variety are located inside the bush, therefore, thickening is not allowed. You can also give the lilac the desired shape using pruning. In this case, you should remember the rules:
- If you cut off the side shoots, the yellow lilac bush will direct the growth in height. By cutting off the top, you can stimulate an increase in the width of the bush.
- Each cut over 1 cm is covered with garden balsam or var.
When trimming the shoots, try not to damage the flower buds. They are located at the top of last year's branches. Removing the buds threatens the bush with the loss of yellow clusters - the main beauty of the variety. In the photo, a correctly formed lilac bush Primrose:

Lyubov Grigorievna Diaghileva, 46 years old, Voronezh
I have been growing lilacs for a long time. I knew Primrose was yellow only at the beginning of flowering. But the variety is unique. It is a lush blooming bush with a pleasant, persistent aroma. It looks unusual. The main thing is to cut it correctly so as not to remove the flower buds. Many expect super characteristics from a yellow shrub. But, the beauty of the variety cannot be taken away, but care is needed for all plants.
Elena Vasilievna Krakova, 55 years old, Krasnodar region
My yellow variety grows in a group. Primrose looks best when there are a lot of bushes. They are lush, well shaped. There were no diseases, pests sometimes annoy. However, there are no varieties that grow without care and attention. Primrose is undemanding for watering. More attention needs to be paid to site selection in order to achieve good flowering. In partial shade, inflorescences are formed less and the color is almost white.
