Planting a cage in open ground

What time to plant

For the cage, you should choose an area with drained, well-moistened and acidic soil, which should be sandy-humus. And least of all, nutritious and alkaline soils are suitable for growing it. As for the illumination, such a plant prefers shaded places; in extreme cases, you can choose a site for it that is protected from direct sunlight from 12 to 16 hours. Landing in open ground is recommended in May.

Landing rules

Prepare a planting hole, which in diameter and depth should reach 0.5 m, at its bottom make a drainage layer about 15 centimeters thick. Place the seedling in the pit and after its roots are straightened, fill the hole with a prepared soil mixture, which should include sand, forest coniferous soil and peat (1: 1: 3). A small amount of sawdust, and another 80 grams of sulfur, need to be poured into the finished soil mixture. The planted plant should be watered with vinegar solution (100 mg of vinegar (6%) for 1 bucket of water), after the liquid is absorbed, the surface of the trunk circle is slightly compacted and the bush is watered again.

Caring for the cage in the garden

In order to successfully grow a cage in your garden plot, you need to water, feed, weed, pinch, trim, and loosen the surface of the trunk circle in a timely manner, remove the growth, cover it for the winter, and, if necessary, protect it from harmful insects and diseases. In order to significantly reduce the number of weeding, loosening and watering, it is recommended to cover the surface of the trunk circle with a layer of mulch (peat, sawdust or wood chips).

Pruning

Formative pruning can only be carried out in the autumn, when the bush has faded. The fact is that in such a plant, inflorescences are formed on young shoots that have grown in the current season. And sanitary pruning can be carried out both in the spring (before the start of sap flow) and in the fall, for this, branches and stems injured, damaged by disease or frost, as well as those that grow incorrectly, are removed.

Shelter for the winter

When grown in mid-latitudes, adult cages can hibernate without shelter, since they have a fairly high resistance to frost. However, while the plant is young, it needs shelter for the winter, for this, in late autumn, the bush should be covered with spruce branches or dried foliage.

How to water

Since this crop reacts extremely negatively to drought, it needs to be watered abundantly and quite often. During a prolonged dry period, special attention should be paid to watering; make sure that at this time the soil in the near-trunk circle is constantly moderately moist. The bush should be watered with well-settled water, which has warmed up in the sun during the day. Watering is recommended in the early morning or in the evening (not earlier than 4 pm), while trying to prevent water droplets from falling on the surface of the leaf plates.

Top dressing

In the year of planting, a young seedling will not need additional fertilizing. It is recommended to feed older bushes shortly before flowering with liquid complex mineral fertilizer.

Cage pests and diseases

If excessively high humidity of the air and soil is observed for a long time, then the likelihood that the bush will be affected by late blight increases. In this case, specks of gray color appear on its branches, the shoots sag and begin to dry out. All diseased parts of the bush are cut off, and 3 treatments are carried out with an interval of 7 days, for this they use Fundazol or Topaz.

The bush can also get sick with powdery mildew, in this case, spots of a whitish color are formed on the surface of its aboveground part. The affected plant must be sprayed with a solution of a product that contains copper or sulfur, for example: Bayleton, Fundazol, Topaz or Topsin.

Also, such a plant can be affected by a viral disease, which poses the greatest danger to it. The fact is that today such diseases are considered incurable. In the affected cell, the color of the inflorescences and stems changes. After the first symptoms of the disease are noticed, all diseased parts of the bush must be cut out and destroyed. Watch the plant for some time, if signs of the disease appear again, then it will have to be removed from the ground and destroyed.

Also, scale insects can settle on the cage. This sucking insect sucks the plant sap from the bush. To get rid of it, the bush is sprayed with an insecticide solution or soap dissolved in water.
