Hydrangea propagation methods
Hydrangea can be propagated in several ways.
The most popular is the cuttings in autumn. Also use seed planting, dividing the bush and propagation by layering. For some reason, gardeners use these methods less frequently.
When planting seeds, there may be problems with the germination of planting material. It takes 2 times more time to get healthy young flowers than when using cuttings or when propagating by dividing the bush.
Oriented to the time of the procedure. It is better to sow seeds in spring, propagate by dividing the bush in late summer or early September, and use root processes in early spring. In autumn, work is carried out with cuttings. Observing all the nuances and fulfilling the necessary requirements, it will turn out to prepare high-quality planting material by spring.
An additional advantage is the possibility of obtaining a large number of cuttings. A man himself selects material for further work.
For propagation of hydrangea in autumn, only its tree-like or large-leaved varieties are suitable. The panicled species is best propagated in spring or summer, as there are difficulties with the procurement and rooting of planting material. Those who nevertheless decided to do this before the onset of cold weather, it is better to use not thin annual shoots, but already lignified branches.
Harvesting cuttings and their processing
Having decided to propagate a beautiful garden shrub of large-leafed, panicled, or tree-like hydrangea, it is worth approaching this lesson with all seriousness.
Each stage of vegetative propagation implies the existence of certain rules, from harvesting cuttings to their rooting and subsequent planting in open ground.
The first thing a gardener will have to face is the preparation of planting material:
- For cuttings using not lignified shoots. They take root faster.
- cuttings are taken from the basal parts of the bush. They take root better than side shoots.
- The age of the bush, suitable for cuttings, is no more than 10 years.
- Take into account the size of the future cuttings. It should be 15-20 cm long, and no more than 6 mm thick.
It is easy to get 2-3 cuttings from one shoot. The main thing is to leave 2-3 pairs of kidneys on each of them. Slices are made oblique at a distance of 1-1.5 cm from the eye. The tool must be sharpened, treated with alcohol-containing agents.
If the chopped parts of the shoots have leaves, they are shortened. This is important for organizing the outflow of nutrients from foliage to root formation. Then, the future planting material at home is treated with biostimulants. Use "Heterroduksin", "Kornevin", "Epin" and others. Before planting, they are soaked in a weak solution of potassium permanganate.
The container for planting is chosen with a good drainage system that will cope with excess moisture. Content may vary.
There are several options for the soil substrate, which is easy to prepare for rooting chopped material at home. To cut the flower in the autumn, choose one of these recipes:
- A mixture of sand and peat (1: 2). The analogue is a ready-made substrate for growing azaleas.
- A mixture of turf land, sand and peat (1: 4: 3), steamed.
- Soil from the garden with coniferous litter and sand (in equal proportions). Humus is also added to such a mixture.
The bottom of the pot is covered with a drainage layer of 2-3 cm. The soil is poured to the top and tamped.
Planting blanks and their germination
Young leaves begin to appear on rooted cuttings
The next stage of hydrangea cuttings in autumn is the planting of harvested material. Small deepenings of 3-4 cm are made in the ground. Cuttings are placed in them. They are placed vertically, at a slight angle. The installed material should not touch the ground with its leaves.
The distance between the seedlings is at least 5 cm. After they are sprayed from the spray gun, and the soil is carefully watered. The container is covered with polyethylene or a glass jar. Further care comes down to simple actions. Seedlings are watered daily, mini-greenhouses are ventilated and maintain room temperature in the room. The rooting period is 2-3 weeks. You can recognize the success of the process by the appearance of new leaflets on the cuttings.
Rooting in water
The rooting of cuttings is possible not only in the soil substrate, but also in a nutrient medium based on water. The advantage of this method is the ability to monitor root formation.
Preparation for the procedure does not require much effort. You will need a container, better transparent, water and cinnamon. 1 tbsp. l cinnamon is added per 200 ml. water. Following actions:
- Billets are dipped into the nutrient medium 1/6 of their total length. For every 200 ml of liquid there are no more than 3 cuttings.
- Cuttings harvested in autumn root in a dark place.
- Monitor the water level in the tank. If it evaporates, the liquid is added. Use only warm and purified water.
Cuttings of hydrangeas in the autumn using water has difficulties. The most common problem is rotting of the material. This is easy to avoid if you saturate the liquid with oxygen daily by aeration.
Planting material will be ready for further use when its roots reach 2-5 cm. The transplant is carried out in fertile slightly acidic soil.
Care for rooted cuttings
When the roots appear on the chopped material, it is taken out and placed in a nutrient substrate from garden soil, peat and sand (2: 2: 1). Planting is carried out in small pots, which are later installed in a shady place. Further care is limited to systematic watering.
Landing at a permanent place of cultivation is organized only next spring. Pre hardening is carried out on the veranda, loggia or balcony.
Growing hydrangea from cuttings allows you to save a lot of time and effort in obtaining a healthy plant. It is only necessary to cut the cuttings from the shoots and root them. Landing on a permanent place of germination will be available in a few months.
