How to plant?
Before you think about planting, you should decide in which place the shrub will be located. The fact is that the site should have diffuse lighting and moist soil. It must be protected from drafts and cold winds. In addition, the soil must have a special composition.
If the site will be in the sun, the plant will not feel too comfortable, will begin to grow worse and bloom. Therefore, the penumbra will be the best option. If there is no opportunity to find a shaded place, then you need to think about the artificial shading of the bush, especially on hot sunny days. Too strong drafts can also have an adverse effect, it is better to sit next to the fence or against the wall of the house.
It should be noted that all hydrangeas are hygrophilous plants. It is necessary to ensure that stagnation of water in the soil is not observed, however, at the same time, its upper layer should not be dry. It is best to stay on neutral or slightly acidic soil. Alkaline soil is categorically not recommended, as over time it will lead to the death of the plant. Neutral soil can be acidified using high peat.
Preparing the landing hole. After this, a soil mixture is prepared, half consisting of earth, and the other half will be a mixture of sand and humus. The seedling is carefully placed in the hole, and its roots are straightened. After this, the pit is filled with soil mixture, as it is compacted and watered. For 1 bush you need 15 liters of water. When watering is finished, you need to mulch the trunk circle.
For this, sawdust, tree bark or horse peat are taken. Mulch is laid in a thickness of 5-6 centimeters.
How to care?
Hydrangea "Silver Dollar" does not require constant careful care, however, you still need to monitor it and perform a number of necessary procedures. Here you can note regular watering, timely top dressing, pruning, as well as preparations for the winter. As for watering, it should be very plentiful. This is especially true on very hot summer days. Evening time will do. A shrub is watered every other day or two, depending on the condition of the soil. For young hydrangeas, 1 bucket of water is enough, for adults, the volume must be increased to 2-3 buckets.
If due to weather conditions the soil does not manage to dry out, watering can be postponed for the required period. For the procedure, only settled water is used, since chlorinated liquid can cause a disease such as chlorosis. Water settles in an open bucket or tank for at least 24 hours; do not cover the container.
As for top dressing, it must be done several times for each season. The first fertilizer application is carried out with nitrogen-containing compounds in early spring. This is necessary in order for the bush to grow stronger and gain green mass. Suitable slurry diluted in water. The proportions should be 1: 10. And it is also permissible to use urea in the amount of 1 tablespoon per bucket of water.
The second top dressing is done at the very end of spring and is designed to build buds. Potassium-containing formulations are used. And also special fertilizers for hydrangeas are suitable. The next time fertilizers are applied during budding. Potassium-phosphorus compounds are suitable, which will act as a stimulator of active and lush flowering. Gardeners recommend using potassium sulfate or superphosphate in proportions of 1 tablespoon per bucket of water during this period.
Final dressing is done after flowering ends. Potassium-phosphorus fertilizers should also be used, with their help the plant will prepare for winter. In addition, cropping cannot be ignored. It is she who is responsible for the high decorative properties of hydrangea, and also acts as a stimulator of flowering.
As already mentioned, this variety of shrubs is frost-resistant. If we are talking about temperate latitudes, he will not need shelter for the winter. However, in regions with more aggressive weather conditions, when the temperature drops below -30 degrees, the flowers will need to be covered, after removing the inflorescences.
Dry grass and leaves are great for this. After that, you can stretch the film on the wire frame, and sprinkle the spruce branches on top.
In the propagation of this variety, vegetative methods are used. This can be layering, cuttings or dividing the bush. Consider each of the methods in more detail. Most often, gardeners propagate hydrangea cuttings. This method is considered the simplest, in addition, planting material is not rare. It is received at the time when the bush is trimmed. The length of the handle should be approximately 15-20 centimeters. For rooting, it is placed in a specially prepared container. The rooting takes place after a short period of time, however, with a transplant into the open ground, you will need to wait until spring.
As for the layering, they are made from lower branches, which are quite long. They are cut approximately in the center, next to the kidney, and a match is inserted there. At the cut point, the branch is dug into the ground. After this, it is necessary to carefully water the layering, then by the autumn it will take root. It will be possible to separate it from the mother plant and transplant it to a new place only in the next season. As for the division method, only large and voluminous bushes are suitable for it. In addition, the procedure is possible only if the plant is planned to be transplanted.
Diseases and Pests
This type of hydrangea and its strains are able to stably tolerate the attack of insects and the influence of various diseases. However, improper care can cause a number of problems. In the case when the nutrient mixture was mistakenly made alkaline, the plant will become ill with chlorosis. With a lack of nutrients, the shoots will begin to grow more slowly, the leaves will begin to stain and fade. These symptoms are similar to the spread of fungal diseases, so you need to inspect very carefully.
When planted in sunny areas, the leaves can be strongly affected by the sun, which can lead to burns. The deterioration of flowering occurs due to improper pruning or cold winds. To prevent insect infestation, the plant should be treated with copper sulfate mixed with laundry soap. From aphids can be saved with the help of wood ash. Nematodes are afraid of potassium permanganate, should be watered with a weak solution of the bush periodically.
If hydrangea is struck by a spider mite, insecticides will come to the rescue.
