Many people wonder how to propagate hydrangea. There are many ways. Some are lighter, others are more complicated, but even beginners, using additional information, will be able to master this process.
When breeding a flower, there are many nuances that must be observed. You need to know about its reproduction, temperature, watering, top dressing. With proper care, the plant will delight the owner with a beautiful flowering and its healthy appearance.
Hydrangea breeding
There are several ways how hydrangea garden propagates:
- By seed germination;
- Root offspring;
- Winter, spring, summer cuttings;
- Layering;
- By dividing the bush.
Methods of breeding a flower
Features of propagation of hydrangeas of different varieties
The flower has many varieties. Its main subspecies are tree-like, paniculate, large-leaved. All these varieties can be propagated in almost any way. To get the result faster, you need to know which breeding method is best.
Tree varieties are less affected by low temperatures, they are not sheltered for the winter, they are easy to care for. The best seat is shaded or partial shade. In hot weather, the flower requires optimal watering. The most convenient methods of propagation are cuttings, layering. Hydrangea of this species can be propagated by seeds, but the process is long. Planting material is best purchased at a specialized store. Division of the bush is carried out to obtain immediately adult and flowering individuals.
Panicled varieties have inflorescences with a diameter of more than 25 cm, their leaves are long and fluffy. The color palette is very diverse. So that the sun does not burn the buds, the plant should be planted in the shade. Bushes of this variety grow rapidly, so they need to be pruned. The resulting cuttings are used for propagation. This method of breeding is a little problematic than with seeds or layering.
Important! The flower tolerates temperatures up to minus 30 degrees.
The most beautiful and moody variety is large-leafed. She has beautiful flowers, large bright green leaves. The bush itself is low and sprawling.
Important! Large-leaved varieties do not tolerate low temperatures, so they are best planted in containers to transfer flowers to another place.
This variety is propagated by cuttings, dividing, layering, seeds, depending on how quickly and what result the gardener wants to get.
Care for hydrangea seedlings
The plant is easy to care for, you need to follow all the rules for growing.
Seedling Care
Watering mode
Hydrangea is very fond of moisture, at the same time it is not recommended to flood the soil very much. Throughout the depths of the roots, the ground should be moderately moist.
Additional Information. In Europe, scientists gave the name Hydrangea hydrangea, which means "vessel with water" in Greek.
Water the plant regularly and abundantly. The optimal regime for an adult bush in central Russia will be 2 buckets per week. In dry weather, watering is increased by 2 times.
Rare heavy irrigation during the dry period is not very favorable for hydrangea.
Top dressing
For lush flowering, the plant needs to be fed. In spring, when the frosts are over, hydrangea is fertilized with any special complex product: Bona Forte, Agricola Aqua, Flower Paradise, Pokon. You can also prepare your own top dressing: mix 20-25 grams of ammonium sulfate (urea), 30-40 grams of superphosphate, 35 g of potassium sulfate.
In cool regions, to improve plant resistance, young foliage is sprayed with Zircon, Epin-extra.
The 2nd stage of feeding geraniums occurs at the beginning of budding. Dilute a mixture of 45 grams of potassium sulfate and 80 g of superphosphate.
The 3rd stage of feeding takes place at the end of summer, the beginning of autumn. Under each bush make up to 20 kg of compost or rotted manure.
Winter preparations
Not all types of hydrangeas need to be insulated for the winter. Panicled variety withstands temperatures up to minus 30 degrees. The tree type is less frost-resistant, only young shoots can freeze in it. In this case, hydrangea is easily restored. These two species need only be spudded a little before winter.
Large-leaved variety is more moody. The flower buds of this hydrangea are formed on the shoots of last year. If they are frozen, then next year there will be no flowering. Therefore, this variety is recommended to be prepared for winter (thoroughly insulated). Especially these measures are required for the middle zone and cold regions.
Methods of propagating hydrangeas at home
Cuttings
The flower can be planted by cuttings. This is one of the easier ways to breed new individuals.
Terms of hydrangea cuttings
Cuttings of hydrangea are carried out in spring, summer and autumn. In spring, pruning is done before the sap flow begins. In summer, cuttings are harvested in June or July.
Winter cuttings
In winter, cuttings are made in large-leaved varieties transplanted into pots. The plant is placed in a room with a temperature of 2 degrees until January, after which it is increased to 10. In February, young shoots are cut into cuttings with two internodes. Large top leaves are cut halfway.
Prepare pots with loose and acidified earth. The lower section is treated with a growth stimulator. Cuttings are planted in pots. Top cover with a glass jar, making a mini greenhouse. Periodically need to be watered and aired.
Cuttings
With the rapid development of a flower, it can be planted in the open ground already in spring, or a pot in partial shade can be placed on the garden plot and left until the fall.
How to cut hydrangea in the summer? A young plant of any variety is easy to grow during this period. In late spring - early summer, cut green cuttings at a right angle below the knot a few centimeters. This year's side shoots are taken, which do not break. Their length should be 10 cm. To reduce evaporation, the lower leaves are torn off. The time is chosen in the early morning or when it is cloudy.
The slice is treated with Cornevin, Heteroauxin or other root-forming agents. Prepare the soil: mix sand, peat, turf in a ratio of 4: 3: 1. Cuttings should be planted at a distance of 5 cm and at an angle of 4 centimeters. It is necessary to maintain a temperature of 20 degrees and spray the cuttings 4 times a day. After 7 days, hydration is reduced to 2 times. Ventilate the greenhouse once a week for 10 minutes.
Rooting will occur in the summer for a month. With the advent of new leaves, watering is reduced. A transplant is done in the fall or already in the spring.
Important! In order for hydrangea to form a strong root system, you need to pick off the buds during the first year after planting.
Spring cuttings
How to propagate hydrangea cuttings in spring? Propagation of hydrangea by cuttings in the spring occurs in a slightly different way. Cuttings are harvested during pruning. Cut in the spring lignified young branches put for 5 days in the water. After that, a cut is made on the branches closer to the kidney at an angle of 45 degrees.
Cuttings of hydrangea in spring also include the treatment of branches with rooting agents. This is necessary to root planting material faster. Prepared cuttings are planted in pots filled with half-washed river sand. The angle of inclination of the branches should be 45 degrees, planting depth 3 cm.
Important! When planted correctly, the cuttings should not touch each other. Leaves do not touch the ground.
The cuttings are covered with a film, periodically sprayed and aired. The temperature in the room should be from 15 to 25 degrees.
Next, seedlings with roots are moved to 10-cm diameter pots. The plant is kept indoors at room temperature and does not allow direct sunlight. In warm weather, hydrangea is planted in the garden.
Semi-lignified cuttings
Reproduction is carried out by lignified cuttings with green shoots for all varieties of hydrangea.
Important! Panicled type is poorly propagated in this way in spring and autumn.
For planting, the soil is taken the same as for green cuttings. Maintain a temperature of 18-22 degrees. Deepen branches by 3 cm and mulch. Pots put in a shady place. The soil needs to be moistened. After 2 months, transferred to a semi-shady place until frost.
Layering
Propagation by layering
This hydrangea dilution differs in slightly different ways. From last year's shoots, young plants are obtained. For breeding, they are bent and dripped in a groove.
This type of hydrangea dilution is carried out in early spring or late autumn. It is necessary to wait for the end of flowering.
Important! Lignified branches for layering are not suitable.
A groove 5 cm deep is radially made around the bush. A branch is bent into each groove with wooden or metal staples. Part of the shoot is left at 45 degrees above, its length is 20 cm.
Important! You can achieve rapid growth by applying parallel notches along the stem.
Sprinkle grooves with earth. It is necessary to water and mulch them. The beginning of the growth of layering can be noticed after 2 weeks. When the shoots reach 10 cm, they need to be spudded.
Sprouts can be planted in the early spring of next year or in the fall. To do this, cut secateurs from the mother plant layering with roots.
Bush division technology
The division of the bush is suitable only for large-leaved and tree-like varieties. The procedure is done in spring or autumn. In cold regions, the best time to separate the bush is spring, in warm regions it is autumn.
Bush separation
First, a bush is dug up and divided in two. In one and the other parts there must be a growth point and a root. Prepare a pit for planting 30 cm deep. The soil should consist of humus, sand and peat. Make a landing.
In the future, you need to water the delenki. To preserve moisture, you can mulch the soil. By autumn, the ground covering layer needs to be increased to prevent freezing.
Seed cultivation
Seed propagation
Small seed. Seeds are found in boxed fruits and are only 3 millimeters. Previously, they are not prepared for sowing.
To grow hydrangea from seeds, you need to determine the planting location. In heating greenhouses, planting is done in December, at home - in March. In open ground, sowing is done in April-May.
For large spaces it is necessary to make a high bed. To lay a drainage on its bottom. The soil should consist of sand, peat and sheet land in a ratio of 1: 2: 4. The earth is compacted and seeds are poured. Sprinkle with washed river sand. Humidify from a spray bottle. It is necessary to cover with foil and pritenit, periodically watering and top dressing with potash and nitrogen fertilizers are required.
For pots, the soil composition is the same. You need to make a hole and sow the seeds. From above they are not covered with earth. Spray neatly with a spray gun so as not to wash the seeds. They also need to be fed.
Sprouts germinate in a month. 95 percent of sowing sprouts. As soon as two leaves grow, the plants are planted in pots or in a greenhouse.
Important! Landing in open ground is done after 3 years. The height of the seedling will be approximately 40 cm.
Care
Rules for sprout care:
- Watering is necessary as the topsoil dries. For this, soft and settled water is taken.
- Periodic loosening of the soil is necessary.
- Regular spraying is required.
- Seedlings need to be removed a little from a window. Lighting is required diffused so that the sprouts do not stop development and do not get burns.
- The optimum temperature is from + 14-20 ° C.
- Exclude drafts.
- When 2-3 leaves appear, the first dive is done, in May, when growing up to 7-8 cm - the second.
- You need to feed 2 times a month with special complex fertilizer.
- Pots with sprouts are tempered, taking them out in warm weather to the street. At night they bring back.
Important! So that the plant does not lose power, the buds break off.
After this, the seedlings are planted in wide, low pots. For wintering, plants need a dark and cool place. Fertilize is not required, water less often.
Observing all these recommendations, you can propagate hydrangea yourself. You can also learn how to properly care for her.
