Why petioled hydrangea does not bloom
Although most varieties are quite attractive in their own right, hydrangeas are usually planted in the garden in order to admire their lush and vibrant blooms. But it so happens that the plant does not bloom, and there are several reasons for this:
- Damage by pests or diseases. If spider mites, aphids and other insects have settled on the plant, or it has suffered from fungal ailments, then you can not wait for flowering. Hydrangeas are not strong enough to form buds.
- Lack of light. Although petioled hydrangea can grow in light shade, flowering from it can only be achieved in the presence of good lighting.
- Excess nitrogen in the soil. If the soil is oversaturated with fertilizers, and in particular nitrogen, the plant will grow rapidly, but it will not be able to form flowers.
- Incorrect cropping. Strongly thickened plants bloom poorly or do not bloom at all. All their energy is spent on maintaining the green mass. Also, flowering will not take place if you inadvertently cut off annual shoots, it is on them that flower buds are laid.
Stalked hydrangea in landscape design
When creating a garden design, petiole hydrangea is used very widely and variedly. Photos of liana hydrangea show that you can use it:
- for decorating a stone surface - a wall, a barn, a garage or a high fence;
- for single plantings - often petiolate hydrangea is fixed on a support made of reinforcement and forms a kind of bonsai 2-3 m high;
- to create Japanese-style gardens;
- for decorating gazebos and arches;
- for braiding the trunks of garden trees.
Basically, the liana-shaped hydrangea is fixed on vertical supports. But sometimes it is also used as a ground cover plant, to decorate the slopes. The disadvantage of this use case is that it is almost impossible to walk on the hydrangea creeping under your feet. Its leaves form a very slippery cover for the soil, this becomes especially noticeable after rain.
Winter hardiness of climbing hydrangea
An adult climbing hydrangea is a very winter-hardy plant that can calmly tolerate frosts down to -35 ° C. This allows you to grow crops not only in the middle lane, but also in Siberia, practically without worrying about winter shelter.
It is recommended to protect from frost only young plants 2-3 years old. It is better to remove them from the support and cover them for a cold period.
Planting and caring for climbing hydrangea
One of the main advantages of the climbing hydrangea is its simplicity. It is very easy to grow an ornamental plant; only minimal effort is required from the gardener.
Selection and preparation of the landing site
Hydrangea needs sunlight, but does not tolerate scorching heat and drafts. Therefore, it should be planted in an area where there is shading and protection from the wind, this will allow the plant to feel comfortable and maintain the ability to bloom.Optimal for culture will be a neighborhood with tall trees, fences or buildings.
The petioled hydrangea prefers soils that are acidic and low in calcium. The plant feels best on loose soils with good drainage, and if the crop is to be planted on heavy soil, then special attention should be paid to sand.
Landing rules
A planting hole for a petioled hydrangea is prepared about 2 weeks before planting, the depth of the hole should be 2 times greater than the root system of the seedling. A mixture of peat, compost, clay, sand and leafy earth is half filled into the hole.
Before planting, the seedling of the plant is kept in water for 12 hours so that the roots are properly saturated with moisture. Then the hydrangea is lowered into a half-filled hole, spreading its roots, and covered with the remains of the soil. In this case, the neck should be deepened by a maximum of 3 cm.
The earth in the near-trunk circle is slightly trampled down and the hydrangea is watered abundantly with water, at least 2 buckets under the root. Moist soil is mulched so that the water does not evaporate too quickly.
Most hydrangea varieties grow quickly, so it is recommended to install supports for climbing shoots already at the planting stage. If the vines are planted in several copies, you need to leave a space of at least 1 m between them, otherwise, as they grow, they will interfere with each other.
Watering and feeding
The climbing plant needs a lot of moisture, so it needs to be watered regularly. In dry warm weather, pour 30 liters of water into the trunk circle twice a week, in rainy weather - only once a week. In this case, the water should be purified and warmed up to room temperature.
The petioled hydrangea is usually fed three times a year:
- In early spring, at the beginning of the growing season, it is necessary to add urea, sulfuric potassium and superphosphate under the root.
- During the formation of flower buds, the liana is fed with superphosphate and potassium.
- In August, 10-15 kg of compost or rotted manure are scattered under the bushes of hydrangeas.
Also in the spring, hydrangea bushes can be watered with a pink solution of potassium permanganate, this will strengthen the plant and protect it from diseases.
Pruning hydrangea petiolate
In order for the petioled vine to look truly decorative, it must be shaped from time to time, without this it thickens and takes on an untidy look.
In the process of pruning, dried shoots and broken branches are removed from the plant, leaving only 6-10 strong healthy lashes. Annual shoots are not cut, but shortened to 5 pairs of buds. The main pruning is carried out in the spring, before the hydrangea starts to grow, and in the fall, all dried inflorescences are usually only removed from the vines.
How to cover a petioled hydrangea for the winter
Due to its high winter hardiness, an adult petioled hydrangea does not need a special winter shelter. Even in Siberia, a liana-like plant can withstand severe frosts, if some of the shoots freeze, then in the spring the petioled hydrangea will quickly release new ones.
Before the onset of cold weather, they are removed from the support and laid on the boards, and covered with spruce branches, non-woven material or a dense layer of fallen leaves on top.
How to propagate a petioled hydrangea
To increase the population of climbing liana on the site, you can propagate an existing plant without buying new seedlings. Basically, gardeners have resorted to two methods of reproduction.
Cuttings
Hydrangea climbing vines reproduce well with the help of stiff cuttings.At the beginning of summer, a cutting about 15 cm long with at least 2 nodes is cut from a healthy lignified stem, the lower leaves are removed and placed in a solution with a root formation stimulator for a day. Then the shoot is planted in a box with a sand-peat mixture, watered and covered with a film.
From time to time, the film is removed to ventilate the shoot and water it again. When a young petioled vine grows stronger and starts growing, it is transplanted under the open sky, usually the next year.
Seed reproduction
The method is used infrequently, since it is difficult to propagate a petioled hydrangea from seeds - efforts may not be crowned with success. The purchased seeds are sown in plastic or peat pots with moist nutrient soil, consisting mainly of sand and peat. The container is covered with glass or wrapped in foil and placed in a room with a temperature of at least 18 ° C.
Before the first shoots of planting appear, you only need to periodically moisten and ventilate daily. Usually, seedlings are shown from the ground after 1.5 months, if you plant the seeds at the end of winter, then in April the seedlings will give the first leaves.
After the leaves appear, the seedlings can be dived. It is advisable to transfer the plant to the ground only after a year, when the seedlings get stronger as they should.
Diseases and pests
Curly petioled hydrangea is a plant vulnerable to pests and ailments. Most often, vines suffer from the following diseases:
- gray rot;
- chlorosis;
- white rot;
- powdery mildew;
- ring spot.
Spring and summer spraying with Fundazol, Fitosporin and other fungicides helps with most fungal ailments. It is necessary to carry out processing with an interval of 2-3 weeks.
Of the pests, the greatest danger to vines is represented by spider mites, aphids, gall nematodes and snails on vines. In order not to miss the infection, you need to regularly examine the vines for harmful insects. In case of infection, the petiole plant can be sprayed with Aktara and other insecticides and acaricides, as well as treated with Bordeaux liquid.
Conclusion
Stalked hydrangea is a very unusual and beautiful ornamental plant. Flexible long vines can densely braid a fence, wall of a house or a gazebo, giving the garden a special charm. At the same time, it is easy to care for the hydrangea - the requirements for its conditions are low.
