Indoor outdoor flowers are propagated according to their characteristics. Cutting panicle hydrangea in summer is the easiest and most convenient way to get young plants of this species. If the procedure is carried out correctly, the stepsons will retain all the varietal characteristics of the mother bush.
Features of cuttings of hydrangea in summer
The summer period is considered the most successful for obtaining young hydrangea plants. This is the time to lay new buds. The period of work for the propagation of hydrangea paniculate hydrangea in summer is from June 10 to July 15. This crop is best suited for this breeding method.
For the procedure to be successful, you must follow the recommendations. They will help even a novice grower to properly propagate the plant.
Rules for cutting hydrangea in summer:
- The parent plant is chosen to be strong, well-grown, saturated with moisture.
- Hydrangeas of the first year of life are suitable for picking cuttings.
Young shrubs are small and green stems with no bark
- If the bush is old, in the summer they cut off the lateral young stems that have grown on the growths of the last season in the lower part of the crown.
- They choose young, strong shoots with leaves and buds, on which the bark has not yet formed.
- For division, stems from the bottom of the bush with green, unblown buds are suitable. They should not bloom.
- If there is a bud rudiment at the top of the shoot, it is cut off.
- Cuttings are harvested in the early morning or in cloudy weather. In this way, plant tissues retain the maximum amount of necessary moisture.
- It is recommended not to cut the stem, but to pinch off the mother bush.
- As soon as the shoot is obtained, they immediately begin to divide it; it should not be allowed to dry out. If you plan to carry out the procedure the next day, the stem is immersed in water.
- After planting, the cuttings take root in the second half of August.
Propagating hydrangeas by cuttings in summer is the easiest and fastest way to get new flowering plants.
How to root hydrangea with cuttings in summer
At the first stage, a young and strong stem is separated from the mother bush. It should have leaves and buds.
Its bottom may stiffen a little, but the top should be elastic, green
Rules for harvesting cuttings
Cut the stem at an angle so that the lower edge is 2 cm below the buds, and the upper edge is 1 cm higher. A step-by-step description of paniculate hydrangea cuttings in summer is presented in the video: https://www.youtube.com/watch?v=aZ9UWJ7tcqE
After weaning the desired stem from the mother bush, they begin to divide the process. It is cut into cuttings of 15 cm each. The lower leaves of the appendix are removed, leaving only a couple of the upper ones.
Cuttings are shortened by half
Preparing cuttings
The lower cut of the cutting is made oblique at an angle of 45 ᵒ, then dipped into a solution of a root formation stimulator: Kornevin, Zircon, Heteroauskin. Use them in accordance with the instructions. You can immerse the stem in Epin's solution for 2 hours.
If there are no special products, the stalk is soaked in honey water for 12 hours (1 tsp. Sweets for 1 glass of liquid). It is immersed in the liquid by a third. Leaves should not be immersed in solutions of growth stimulants.
The upper cut of the cutting should be even, it is treated with a weak solution of manganese or brilliant green. This is necessary to disinfect the unprotected part of the plant.
Landing
Immediately before planting, they begin to prepare the soil. Its composition is as follows: 2 parts of river sand and 1 part of humus or garden soil. Once the mixture is ready, it must be well moistened.
Cuttings are deepened into the soil 3 cm to the first leaves, at a slight angle. The soil should be loose and moist.
The distance between plants is maintained at least 5 cm
After planting, the topsoil is crushed with coarse sand and sprayed with a spray bottle. Saplings are watered with a weak solution of potassium permanganate.
Cutting hydrangeas in summer can be done in water. To do this, the cuttings are dipped not into fertile soil, but into clean, transparent water.
The sun's rays penetrate well through the liquid, promoting the growth of root processes, the process of root formation is also clearly visible
Hydrangea plants in summer are best kept indoors or in a greenhouse, shaded from direct sunlight. With a closed method of germinating cuttings, the risk of infection with garden diseases is reduced, the plant is protected from attacks of pests and sudden changes in air temperature.
The water in the container is changed 3 times a week, otherwise the decay process may begin. To prevent this, an activated carbon tablet is dissolved in the liquid.
Roots are formed in 20-30 days.
With this method of cutting hydrangeas in the summer, there is a risk of decay of the seedling.
Surviving plants have strong immunity, tolerate temperature changes well.
Care of cuttings
A container with planted cuttings is covered in summer with a plastic lid or foil. This technique will help create a greenhouse effect.
During this period, young plants need warmth and high humidity.
The optimum air temperature during the day is + 22 ᵒС, and in the evening + 18 ᵒС.
Every day, the cover is removed from the container for half an hour, airing the cuttings. In summer, they should not be in the sun. Also, once a day, seedlings are sprayed with a spray bottle and watered with a watering can at the root. If it is not too hot outside, the amount of watering is halved.
After about a month, in the summer, in mid-August, the cuttings of the hydrangea will take root.
This can be determined by the young small leaves that appear on the top of the seedling.
After that, the shelter is removed from the container, to accelerate growth in the summer, top dressing is used in the form of weak solutions of nitrogen, phosphorus and potassium.
Transfer to a permanent place
Cutting of hydrangeas in summer in August is completed by transplanting the rooted shoots to a permanent place. As soon as the roots of the hydrangea grow up to 3 cm, a couple of new leaves will appear on the stem, young plants are planted in separate containers.
Their depth and diameter must be at least 10 cm
Watering hydrangeas in the summer with cuttings in July is carried out at least 2 times a week. For the winter, pots of flowers are brought into the cellar. Watering during this period is completely stopped.
You can dig a young plant in your garden plot.
It is imperative to insulate the seedling with a heap of leaves or a spruce tree
The hydrangea is transferred to a permanent place next spring. It is pre-tempered by taking it outside for an hour every day.
As soon as the first leaves begin to appear, watering is resumed. After warm weather on the street, the cuttings of the hydrangea are transferred to the garden. For landing, choose a place in partial shade. The bright sun is detrimental to the plant, and in the shade the hydrangea buds become smaller, become faded.
The soil in the garden is carefully dug up. Before planting, 1 tbsp is added to each hole. l. universal mineral or potassium-phosphorus fertilizer.You can purchase a special ready-made feed for hydrangeas.
The hole is dug out taking into account the earthen coma, with which the flower is transferred to a permanent place
The soil is mixed with universal fertilizer 1: 1 and a third of the planting hole is filled with this mixture.
In the soil mixture, a depression is made for the rhizome of the hydrangea. After that, the plant, together with an earthen clod, is transferred to the planting hole. The root is covered with soil mixture, lightly tamped with your hands.
Then the grown hydrangea stalk is watered
It is better to mulch the soil on top to retain moisture.
Before planting, watering of the grown hydrangea cuttings is stopped for a couple of days. This is necessary in order to easily remove the earthen clod from the container and transfer it to the soil.
In order for the bush to grow lush, after planting it is shortened by a third of its length. If the first buds appear on the hydrangea soon, they are cut off. This helps to strengthen the root system.
For the winter, young plants are sheltered only in the first couple of years. Older shrubs can easily tolerate frosts.
Conclusion
Cutting panicle hydrangea in summer is the most effective way to propagate this crop. It is suitable for almost all varieties of street flowering shrubs. In the process of cuttings, you can get a large number of young, strong seedlings. They will fully retain all the varietal characteristics of the mother bush.
