Botanical features of large-leaved hydrangea
Large-leaved hydrangea, or garden (Hydrangea macrophylla) is a highly decorative and fast-growing type of hydrangea native to Japan and China. The maximum height in a region with severe winters is limited to 1-2 m.This species has erect shoots, ovoid, large, bright green leaves and flat wide inflorescences with a diameter of up to 15 cm and a height of up to 10 cm, consisting of fruiting lilac or blue and large pink, with irregular bright strokes, reaching up to 3.5 cm in diameter, sterile flowers.
Hydrangea inflorescences, the flowering of which starts in July, remain highly decorative until next spring: they dry out, but still remain very attractive.
Large-leaved hydrangeas, the fashion for which came to us from the West, so captivating in tubs and pots, so unique in their beauty for their almost spherical dense inflorescences and bright foliage - shrubs are still capricious and unadapted to the harsh climate. But this does not prevent them from growing even in regions with harsh winters.
And although these beauties need special care and protection for the winter, their beauty, nevertheless, is unmatched. And it doesn't matter whether you decide to transplant a potted hydrangea into the garden or originally purchased a garden plant - the principles of growing and caring for the shrub will still be the same. The main difficulty in growing large-leaved hydrangeas is associated with the need to preserve last year's shoots, on which this type of hydrangea blooms, during a long and harsh winter, not only without freezing, but also without damping off.
Reproduction
To breed this shrub, several breeding methods are used:
-
cuttings;
-
dividing the bush;
-
layering.
For the first method, cuttings are harvested in the summer. To do this, cut off young stems that did not have time to lignify. Propagation by cuttings is carried out as follows:
- the cut parts are placed in water for 2-3 days;
- the lower leaves are removed from the cuttings;
- shoots are treated with a preparation to stimulate growth;
- prepared cuttings are planted in a container with soil, which includes peat and sand;
- the container is covered with polyethylene or glass, creating a mini-greenhouse;
- planted cuttings are kept in the basement;
- seedlings need to be moistened periodically;
- at the end of August, the cuttings already have a formed strong root system, and they are quite ready for planting in open soil.
When breeding hydrangeas by division, at the end of flowering, the bush is dug up and divided into several parts, each of which must have at least one growth bud. Then each flower is planted in a separate planting hole with pre-prepared soil. For this, organic matter or mineral dressings are introduced.
With the help of layering, shrubs can only be propagated in the spring season. This method of reproduction is used quite rarely, since the result is not always positive. For him:
- dig a hole 15-20 cm deep near the bush;
- the lower young shoot is placed in the hole and sprinkled with soil;
- water the branch as the soil dries up;
- after the formation of new leaves on the cut, it is separated from the mother plant and planted in a new place.
