Home outdoor flowers are propagated according to their characteristics. Cutting hydrangea paniculata in summer is the easiest and most convenient way to get young plants of this species. If the procedure is carried out correctly, the stepchildren will retain all the varietal characteristics of the mother bush.
Features of hydrangea cuttings in summer
The summer period is considered the most successful for obtaining young hydrangea plants. This is the time for laying new buds. The period of work for cuttings of hydrangea tree paniculata in summer is from June 10 to July 15. This culture is best suited for this method of reproduction.
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 hydrangeas in summer:
- The parent plant is chosen strong, well-grown, saturated with moisture.
- Hydrangeas of the first year of life are suitable for taking cuttings.
Young shrubs are distinguished by their small size and green stems on which there is no bark.
- If the bush is old, in the summer the lateral young stems that have grown on the growths of the last season in the lower part of the crown are cut off.
- 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 shouldn’t bloom.
- If there is a bud rudiment at the top of the shoot, it is cut off.
- Harvesting of cuttings is carried out in the early morning or in cloudy weather. So plant tissues retain the maximum amount of necessary moisture.
- The stem is recommended not to be cut, but to pinch off from the mother bush.
- As soon as the shoot is received, they immediately begin to divide it, it must not be allowed to dry out. If the procedure is planned for the next day, the stem is immersed in water.
- After planting, the cuttings take root in the second half of August.
Propagating hydrangeas from cuttings in the summer is the easiest and fastest way to get new flowering plants.
How to root hydrangea 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 become a little stiff, but the upper part should be elastic, green
Rules for cutting 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 cuttings of paniculate hydrangea 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 shoot are removed, leaving only a couple of upper ones.
Shanks cut in half
Preparation of cuttings
The lower cut of the cutting is made oblique at an angle of 45 ᵒ, then immersed in 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 means, the stalk is soaked in honey water for 12 hours (1 teaspoon of sweetness per 1 glass of liquid). It is immersed in 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, start preparing 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.
The cuttings are deepened into the soil by 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. Seedlings are watered with a weak solution of potassium permanganate.
Cuttings of hydrangeas in the summer can be carried out in water. To do this, the cuttings are lowered not into fertile soil, but into clean, clear 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 the summer are best kept indoors or in a greenhouse, shading from direct sunlight. With a closed method of germinating cuttings, the risk of infection with garden diseases is reduced, the plant is protected from pest attacks and sudden changes in air temperature.
The water in the tank is changed 3 times a week, otherwise the process of decay may begin. To prevent this, an activated charcoal 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 rotting of the seedling
Surviving plants have strong immunity, tolerate temperature changes well.
Cutting Care
The container with planted cuttings in the summer is covered with a plastic lid or film. This technique will help create the effect of a greenhouse.
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 shelter 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 gun and watered with a watering can under the root. If the street is not too hot, the number of waterings is reduced by 2 times.
About a month later, in the summer, in mid-August, hydrangea cuttings will take root.
You can determine this by young small leaves that will appear at 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
Hydrangea cuttings in summer in August are completed by transplanting rooted shoots to a permanent place. As soon as the hydrangea roots grow 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 when cuttings in July is carried out at least 2 times a week. For the winter, flower pots are brought into the cellar. Watering during this period is completely stopped.
You can dig a young plant in the garden.
Be sure to warm the seedling with a pile of leaves or spruce forest
The hydrangea is transferred to a permanent place next spring. It is pre-hardened, taking it outside for an hour daily.
As soon as the first leaves begin to appear, watering is resumed. After the establishment of warm weather on the street, hydrangea cuttings 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 and 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 top dressing for hydrangeas.
The hole is dug taking into account the earthy coma, with which the flower is transferred to a permanent place
The earth is mixed with universal fertilizer 1: 1 and a third of the planting hole is filled with this mixture.
In the soil mixture, a recess is made for the hydrangea rhizome. After the plant, together with an earthen clod, is transferred to the planting hole. The root is covered with soil mixture, lightly rammed with hands.
Then the grown hydrangea stalk is watered
It is better to mulch the soil from above to retain moisture.
Before planting, watering the grown hydrangea cuttings is stopped for a couple of days. This is necessary in order to easily remove the earthen lump 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 the length. If soon the first buds appear on the hydrangea, they are cut off. This helps to strengthen the root system.
For the winter, young plants are covered only in the first couple of years. Older shrubs easily tolerate frost.
Conclusion
Cutting hydrangea paniculata in summer is the most effective way to propagate this crop. It is suitable for almost all varieties of outdoor flowering shrubs. In the process of cuttings, you can get a large number of young, strong seedlings. They will fully preserve all the varietal characteristics of the mother bush.
