Rules for pruning spirea varieties blooming in summer
Delicate pink beauty spirea pleases its owners with abundant flowering at a time when many spring flowers have long dried up under the summer sun. An unpretentious and undemanding shrub needs only two conditions - moistening the soil on dry days and a shearing.
Why cropping?
Over time, spirea often loses its attractive bush shape: it begins to fall apart in different directions, and individual branches may even dry out. Regular pruning will help restore the decorative and neat appearance of the shrub, as well as rejuvenate it.
For summer varieties spirea pruning has not only decorative value, because this group of shrubs blooms on the shoots of the current year. Timely haircuts will help stimulate abundant and lush blooms.
In addition, some varieties of spirea release a large number of shoots from the main roots, thus occupying an increasingly large area. Periodic removal of part of the young shoots will not allow the bush to go beyond the limits of the flower bed allocated for it.
Spring pruning features
The first pruning must be done even during the spring planting of the bush, cutting the branches in half. Also, all damaged, weak and dry shoots are removed (if any of the seedling).
It is necessary to cut off shoots before the first dormant bud, directed outward.
Depending on the age of the spirea, there are some features of its pruning:
- In the first two years of life, all shoots must be evenly shortened.
- In the third year after planting, you should completely cut out the old branches, which are three years old. They will no longer bloom and will only thicken the bush.
You can start forming a bush in March, as soon as a stable temperature is established and the threat of return frosts has passed.
How to properly trim spirea in summer?
In summer, the shrub needs attention, especially during flowering, which occurs in July and lasts until the end of summer (some varieties bloom already at the end of June). At that time spirea should be inspected periodically.
As the inflorescences fade, they must be carefully cut off with a pruner, preventing the formation of seeds, otherwise the bush will stop growing. Removing dry flowers will not only promote the formation of side shoots, but also prolong the flowering itself.
