And the composition does not matter. To balance the substrate, peat, turf or leafy soil, and sand are usually added. Lands with poor drainage capacity should be drained to eliminate stagnant moisture. Excess fluid on the site can cause root decay.

A couple of days before planting, the root system and shoots are cut 3-5 cm, dry, damaged areas are removed. And then leave for 2-3 hours in a container with water. Immediately before the procedure, the roots are treated with a clay mash.
Landing rules
Planting plants in the ground should be planned for spring or autumn. The weather on the day of planting should be cloudy or rainy. Deepening must be kept for 4-5 days. Its size is calculated from the volume of the root system with a 1/3 margin for further development. The approximate depth is 0.5 m. When choosing a place, it should be borne in mind that the Genpey spirea has abundant root growth. When all the preparatory work is completed, it's time to start planting:

Watering and feeding
The root system of the Japanese spirea Genpei is located close to the surface of the earth, so it acutely feels a lack of moisture. Lack of water adversely affects growth and flowering rates. At the same time, watering should be moderate. In dry periods, it is enough to moisten the shrub twice a month. A volume of 10 liters of water is sufficient for one plant.

Pruning
The Japanese spirea Genpei requires annual pruning. The first stage involves the sanitary removal of dry, diseased shoots in the spring. It is advisable to do this before the appearance of new foliage. A dry branch should be removed before a living bud. If the shoot is underdeveloped or stunted, it is cut off completely.
The second stage is the formation of the crown. It means giving a beautiful appearance and regular shape to the bush. The flowering of the Japanese spirea Genpei also depends on this procedure. The more shoots are removed, the stronger and younger the shrub will look.
After four years of age, the plant needs rejuvenating pruning. The bush is cut completely, leaving 30 cm from the ground. Each pruning procedure should end with top dressing: a solution of manure with superphosphate - 10 g of a mineral preparation is needed for 10 liters of the mixture.

Spray the cuttings with water three times a day. In late autumn, plant in a garden bed and cover with dry leaves. In the spring, after the appearance of the buds, it can be transplanted to a permanent place.
Young plants also quickly take root through layering. The breeding process in this way falls in the spring. A couple of side shoots are bent and fixed to the ground. Be sure to sprinkle it on top with earth and water it. When the sprout is rooted and grows, the branch can be detached from the mother plant.
The division of the bush can be done in spring and autumn. If the procedure is scheduled for a warm period of the year, then you should have time to complete everything before the first leaves appear.
