How weigela reproduces - the best ways
Weigela is very popular among gardeners for its lush and long flowering. It is not surprising that many are interested in the question of how weigela reproduces. There is nothing difficult about this: Weigelu deciduous shrub can be spread across the site using conventional techniques. We bring to your attention a brief look at them.
So, weigela can be propagated in two ways:
- seed;
- vegetative.
How to grow weigela from seeds?
Seed reproduction in the case of weigela has its own characteristics. The fact is that fresh seeds have the highest percentage of germination. The maximum, how many they can be stored - is two years. In this regard, there is no special sense in messing with seedling boxes or pots.
If you decide to grow a crop from seed, you don't need to do anything. Better to let the seeds fall into the soil on their own and germinate.
With the arrival of spring, choose the strongest and most developed seedlings, the rest can be removed. Without replanting, continue to grow seedlings for another two years. But after this time, it is quite possible to relocate young bushes to a permanent place.
Plants obtained from seeds may not retain their species characteristics.
Weigela: methods of vegetative reproduction
Most often, flowering shrubs are propagated vegetatively, rooting:
- cuttings of summer green shoots;
- last year's semi-lignified cuttings;
- young root shoots;
- layering.
Plants obtained from cuttings and cuttings must be grown before transplanting to a permanent place for 3 years.
When and how to carry out cuttings?
Cutting can be combined with pruning a bush. The time for harvesting cuttings depends on which branches you will use for propagation, namely:
- green shoots should be cut at the end of June;
- last year's branches - in the spring, before the start of sap flow.
Cuttings can also be taken from root shoots.
The length of the cuttings should be no more than 15 cm. The lower leaves should be removed, and the upper ones should be shortened by half. It is better to root them in a mixture of sand and peat, which is sprinkled on top with a layer of sand. It is enough to deepen the cuttings by 1 cm, and cover with a bottle on top. It must be removed daily for ventilation. When a young twig appears on the cuttings, it should be pinched for tillering.
The bottom cut can be processed Kornevinto speed up root formation.
How to propagate weigela by layering?
To get an independent plant with its own roots, you need to find the lower branches on an adult bush. Choose from them those that are closest to the ground and bend. In the place of contact, damage the bark on the shoot and sprinkle well with soil. As early as next spring, the layers can be separated from the mother plant and sent for growing.
