Reproduction of forsythia by cuttings in spring and summer: advice from experienced summer residents
Gardeners living in the middle lane practice forsythia propagation by cuttings in the spring. Harvesting of planting material is carried out either in the summer or at the end of autumn. In June, green shoots are selected, and in November / December, lignified ones. In all cases, farmers are guaranteed to receive healthy seedlings that will take root quickly and without problems. To achieve an excellent result in this matter, it is necessary to carry out the preparatory work correctly.
Forsythia propagation by cuttings in spring
Propagation of forsythia by cuttings includes the correct cutting technique:
- length - 15-20 cm;
- the upper cut is made straight, and the lower one is made at an angle to increase the area of root formation;
- the distance from the edge to the first knot on both sides is 1-2 cm.
The resulting plant parts are sent to a cool cellar or refrigerator for storage until March. Forsythia propagation by cuttings in spring is carried out in 2 ways. Vegetative shoots are planted in containers with nutrient soil or directly on a flower bed. Before this, the slices are updated. Fertile soil from the garden is taken as a soil substrate. It is mixed with perlite or sand.
Agricultural technology for planting in greenhouses:
- embedment depth 4-5 cm;
- the distance between the seedlings is 5-7 cm;
- shelter in the form of a plastic cover, glass.
For successful rooting, cuttings are immersed in a solution of Heteroauxin or Kornevin. After 3-4 hours of infusion (sometimes 8-10 hours), they are planted in the ground.
Unusual seedlings are watered regularly to keep the topsoil moist. The greenhouse is ventilated daily for 15-20 minutes. With this cuttings forsythia in the spring (in April / May), the rooted seedlings are transferred to a permanent place in the garden. However, experienced growers leave the plant in a pot for another 1 year so that it grows a strong root system. Then the shrub will take root perfectly in the front garden and will start growing faster.
Planting forsythia cuttings in open ground
For planting prepared shoots, choose relatively warm, but not hot weather. As already noted, cuts are made again in the upper and lower parts. The bed is dug up, forming grooves up to 10 cm deep. Between individual specimens, an interval of 5-7 cm is maintained.
Up to 2-3 buds are left above the ground. The near-bore area is slightly tamped. The planting must be watered.
Since it is quite easy to propagate forsythia by cuttings in the spring, many do not take this event seriously. However, the young plant must continue to be taken care of, especially during the winter. At the onset of the first frost, the plantation is covered with spruce branches or fallen leaves.
Reproduction of forsythia by cuttings in water in spring is rarely carried out. In most cases, such specimens turn out to be weak and, as a result, die.
When the heat comes in, the protective structure is removed. Further, the sprouts are closely monitored. They are watered so that the rhizome is constantly in a humid environment. However, the area should not be excessively wet. Otherwise, the shrub will not be able to breathe and will start to rot.If the technology of forsythia cuttings is followed correctly, then in a month the first leaves will appear on the trunk.
Reproduction of forsythia by green cuttings in summer
After the flowering of the plant, young shoots are cut from it, which are not more than 1 year old. These branches should be green or just starting to acquire a woody texture. On the bark (near the base), they will show a fine dot pattern.
It is better not to take specimens that are too thick, otherwise the rooting process will be delayed. Separate parts of the plant together with the "heel".
Now it is important to understand how forsythia reproduces by cuttings in summer. The technique of planting vegetative shoots does not differ from the spring one. They are planted both in containers and in open ground.
However, in all cases it is necessary:
- cover the sprouts with a glass jar or film;
- water regularly to keep the ground moist;
- shade with a special shelter.
The length of the cuttings is 15 cm. An even cut is made at a height of 1.5-2 cm from the upper nodes. All the lower leaves are cut off, and the 2 upper leaves are cut by half.
A month later, full-fledged roots will form on these miniature seedlings. Together with an earthen lump, vegetative shoots are dug up and transplanted into a flower bed. At the same time, some gardeners leave this procedure for the next year.
Propagation of forsythia by layering
This is one of the most reliable and affordable ways to propagate a culture. It is carried out either in the spring or in August-September. For this, young, healthy and flexible branches are chosen.
Then a few simple procedures are carried out:
- dig a ditch 2/3 long of the marked shoot;
- deepen it up to 10 cm;
- remove leaves on the main part of the trunk;
- make several cuts in the rooting area;
- bend the branch to the bottom of the trench;
- pinch with V-shaped spacers in 2-3 places;
- covered with earth, which is pre-moistened.
The shoot should take root next spring. Then it is separated from the mother bush and transplanted to a new location. A year later, charming flowers will appear on the young plant.
Forsythia bush care
Flowering is the main feature of this shrub. Therefore, it must be looked after in such a way as to promote the formation of new buds.
Since forsythia belongs to the olive family, it needs regular:
- Watering. Especially on hot days, as well as in windy weather, when the air currents dry out the earth.
- Top dressing. At the beginning of spring, the rotted is evenly distributed around the bush. manure... In April, mineral fertilizers are applied at the rate of 70 g / bush. During flowering, the plant is fed with a solution of the drug Kemira Universal.
- Scraps. In the early years, only frozen branches are removed. For 3-4 years in the summer, formative pruning is carried out. Shoots are shortened by half. Old branches are cut, leaving 5-6 cm hemp.
It is in this mode that the ornamental shrub is taken care of. These conditions will be an excellent basis for successful propagation of forsythia by cuttings in the spring. After a few years, it will be possible to form a hedge or a mysterious one from the rooted shoots. rockery.
