Seedling and planting preparation

When buying Red Rocket barberry seedlings in a specialized store, special attention should be paid to the condition of the roots and leaves - they must be healthy. Before planting in the ground, it is recommended to lower the roots for several hours in a bucket of water.

Seedlings purchased in a container are carefully removed with the soil and lightly watered so that the soil and roots are moist when planting.

Before planting, the selected area is dug up to enrich the land with oxygen and remove weeds. If the acidity is very high, then it is necessary to add a solution of lime or wood ash during digging.

Landing rules

For a single planting, it is recommended to place the bushes at a distance of about 1.5 m from each other. Planting a dense hedge will require 4 barberries per 1 running meter. m.In the free-growing version of the bushes, when planting a hedge, there should be at least 0.5 m between the seedlings.

Landing is carried out according to the following algorithm:

  1. Dig a hole corresponding to the root system of the seedling (most likely, it will be 0.5x0.5x0.5 m in size).
  2. Lay drainage 15 to 20 cm high.
  3. Fill in half with a fertile mixture consisting of: land from the site, humus, sand in approximately the same proportions.
  4. Place the seedling in the center.
  5. Fill up the earth to the level of the plot, tamp it slightly.
  6. Drizzle with water.

Mulching with tree bark, dry foliage, and a small decorative stone of the trunk circle will allow the earth to keep moisture longer, and not dry out in hot weather. To plant a hedge, they dig a trench where all the seedlings are placed.

Watering and feeding

The irrigation regime of the Red Rocket barberry depends on the climatic conditions of the place where it grows. This type of shrub is drought-resistant and does not like waterlogging. If the summer is rainy, then the barberry does not need to be watered, there will be enough natural moisture. In dry weather, do 1 watering per week. A bucket of water is poured onto the bush.

If the Thunberg Red Rocket barberry is planted according to the rules in a fertile mixture, then the first feeding is carried out for 2 years and further, nitrogen fertilizers are applied once every 3-4 years. Complex fertilizers are applied before each flowering.

Pruning

Young bushes, planted for free growth, carry out 2 types of pruning: rejuvenating and sanitary.

Sanitary pruning is done every spring after the snow melts, before the leaves begin to open. Remove frozen, dry and diseased shoots.

A rejuvenating haircut is needed when the Red Rocket barberry is 7-8 years old. It is carried out in the fall, removing old branches growing near the ground, and removing part of the young stems in the crown.

There is one more type of trimming - molding. It is used when growing a hedge or to give a bush a certain shape. Such pruning is done, a couple of years after planting the seedling, when the barberry has faded.

Advice! Based on the desire, molding pruning of Red Rocket barberry can be carried out 2 times during the summer: in June and August.

Preparing for winter

The unpretentious care of the Thunberg Red Rocket barberry variety also includes its winter hardiness. The territory of Russia has different climatic conditions. This must be taken into account when growing barberries. If the winters are not very frosty and snowy, then there is no need to cover the bushes, only very young ones - 2-3 years old.

When a severe frost is expected, and there is little snow, then in order to preserve the plant, it is better to cover it for the winter with spruce branches, peat or straw.

Reproduction

There are different ways of breeding Red Rocket barberry. Not all of them can be successfully used in the garden. But a novice gardener should know about them. You can propagate this variety:

  • cuttings;
  • layering;
  • dividing the bush;
  • seeds.

Layers and cuttings are most often used, since with this method of propagation, the varietal qualities of barberry are preserved. Cuttings can be carried out at any time of the year, except for winter. Summer cuttings are considered the best for gardeners. They are green and take root faster.

The method of dividing the bush is applied to young plantings, which are easy to dig up without greatly damaging the roots. But the probability of survival of a young shrub is not always 100%.

Seed propagation is also possible with proper seed preparation. Seeds can be planted in autumn or spring after 3 months of stratification. This method requires a long time (about 2 years), has poor germination and does not retain the qualities well enough due to which this Red Rocket variety is grown.

If the disease has just appeared, then you should immediately fight it. Otherwise, premature leaf fall will begin.

The insect, the barberry aphid, causes the leaves to dry out and wrinkle. Against her, the bush can be sprayed with a solution of laundry soap or tobacco. The flower moth, which eats the fruits, is considered dangerous. To combat the caterpillar, the bush is treated with chlorophos or appropriate insecticides.
