Watering
Although the culture does not apply to those that require a special irrigation system, there are still some recommendations for improving its living conditions. If the plant was planted in the spring, its root system is not yet strong enough, so regular soil moisture is necessary. In the summer, flowering varieties need abundant watering - twice a week each bush is expected to have at least 15 liters of water. Also, young plants planted by the method of cuttings need special additional care - they are watered up to 4 times a day.

A compact bush will require about half a bucket, and a large one - up to 3 buckets.
Mineral compounds are introduced before the flowering bush. These complex mixtures must be introduced into the soil at the rate of 80–100 g per 1 m2. The area is calculated by the diameter of the crown of the bush.

But sowing allows you to get not one or more representatives of spirea, but many at once.
Propagation of Japanese Spirea Seeds

The lowest branches of the shrub should be tilted and pressed to the ground, sawed, for example, using wire, and sprinkled. Fixation points should be watered regularly. By the fall, new bushes are forming here.
