Reproduction methods
Each gardener chooses for himself the most convenient way of breeding birch spirea.
You can cut a shrub in the fall. During the procedure, branches are cut that grow vertically upward, young, and have had time to lignify. After that, only the apical leaves are left, and the branch is placed in a solution for root formation. Cuttings are planted in containers with moistened sand with a slight slope. In autumn, they are buried in the ground, and covered before spring planting.
An easy way for novice gardeners is to get cuttings. The lower healthy shoots of the bush must be dug into the soil under the mother plant in the prepared shallow pits, and, having securely fastened, constantly moisten the near-stem circle of an adult bush
Along with this, other agricultural work can be carried out, but with caution, trying not to damage the process of root formation in the future seedling. For the winter, the land is mulched, covered with protective materials, and shoots with roots are separated in the spring, then they are planted in open ground
By dividing the bush
So you can get cuttings from plants at the age of 3-4 years. In the fall, water the ground under the spirea well, dig in in a circle, remove the bush and divide it into several parts with a sharp tool. Each must have an intact trunk and strong roots. Shrubs can be planted in the soil, but for the winter they will have to be carefully covered to prevent freezing.
The seed method is not very popular, since it takes a lot of time and effort.
High quality seeds are very important, otherwise they may not sprout. Seedlings are sown in the spring, after having carried out antifungal treatment and stratification
In greenhouse conditions, seeds germinate, then they are planted. For the winter, young plants are best moved to greenhouses, and planted in a permanent place next spring.
Care
With proper care, small seedlings can grow lush, beautiful shrubs that will brighten up your garden.
Top dressing
In the spring, shortly before flowering, spirea bushes should be fed with nitrogen-containing or organic fertilizer. In the middle of summer, you need to fertilize with mineral fertilizer, and by the end of summer it is better to use fertilizers without nitrogen, with a high content of phosphorus and potassium.
Pruning
The shrub should be pruned every spring. If the variety is from early flowering, then only the apical shoots need to be cut, and if the variety begins to bloom later, then up to 1/3 of the bush can be cut. It is imperative to cut off damaged or dry shoots. After the age of the bush reaches 7 years, you can make anti-aging pruning.
Watering
This plant is quite drought tolerant, but regular watering is a must. About once a month, at least a bucket of water should be poured onto the spirea bush, and if the temperature is high, then watering should be carried out at least once every 2 weeks. A young shrub or seedling planted this year can be especially sensitive to a lack of watering. To prevent the formation of a crust around the trunk, after watering the shrub, you need to loosen the soil with care. Loosening does not need to be carried out deeply, as there is a possibility of damage to the root system.
Planting and leaving
The timing of planting spirits depends on the flowering time of the species. Spireas blooming in spring are best planted in autumn. Until spring, the bush will take root well and by spring it will be covered with white. Summer flowering spireas can be planted in both spring and autumn.
When planting all spirits, regardless of the flowering period, the rule is strictly observed: spring planting - before the leaves bloom, autumn - after the end of the leaf fall.
If a seedling with an open root system, match the ground and underground parts of the plant. That is, shorten overgrown roots, and if the roots are damaged and very dry, shorten the branches.
Remove the seedling with a closed root system from the container, spill it well with water, and if necessary (if the lump is very dry) soak it in a bucket of water, and only then plant it in the chosen place.
If, several years after planting, you notice that the branches of the spirea begin to dry out and become bare, and the inflorescences become smaller, this means that the shrub is aging and it is time to rejuvenate it. For this very low - "on a stump" - cut the branches. After such a radical procedure, your spirea will become even more beautiful.
Spireas are photophilous. The best place for them is sunny. But they can easily endure partial shade, however, the flowering will not be as abundant as it could. Any soil is also suitable, even not very fertile.
Most spirits do not need to be watered frequently - an essential detail for Sunday gardeners. But there are exceptions: felt spirea is hygrophilous so much that it grows well in waterlogged areas.
