What time to plant

Locating buckthorn seedlings in the open ground is done in the springtime. A site for such a crop should be chosen that is well lit and also has reliable protection from the wind.

Suitable soil should be slightly acidic (pH from 6.5 to 7.5), and also light and well-drained. The knapweed grows best in sandy loam soil. Near a body of water in which fish live, this plant can not be planted, because its composition includes poisonous substances.

Prepare in advance the soil mixture that will be needed to fill the planting hole, it should include sand, sod soil and humus (2:1:1). In this soil mixture should be poured full mineral fertilizer, for example, you can use Kemira-Universal, with 120 grams of the substance per 1 square meter of land. Before planting, the potting mix should be thoroughly mixed.

Towing instructions

If several plants are planted, the distance between them should be at least 0.3 m.

The size of the planting hole should be twice the size of the root system of the plant taken together with the root ball. If the planting is done in heavy soil, a good drainage layer should be made on the bottom of the planting hole, the thickness of which should be about 20 centimeters. When planting a seedling in sandy soil, the drainage layer should have a thickness of about 10 centimeters.

The seedling should be placed in the middle of the planting pit. Then the free space is filled with the prepared soil mixture.

Fill the hole gradually, all the time tamping a little soil mixture. After planting the root neck of the plant should be at the same level with the surface of the plot. When the planting of the seedling is complete, it should be liberally watered. And after the liquid has been absorbed into the soil, its surface should be covered with a layer of organic material, which should be 30 to 50 mm thick.

Garden care of the rockitnik

Ruscus: planting and care in the open field, species and varieties with photos

Growing a rockitnik in your garden plot is quite simple.

Such a plant will need timely watering, feeding, trimming, loosening and mulching the surface of the root circle, removing weeds and preparing for winter. Don't forget about preventative treatments for diseases and pests.

How to water and feed

Water the bush after the top layer of soil in the root zone dries out. Watering should be quite abundant. You should pay attention to the fact that hybrid rocket plants compared to the species are more demanding to watering.

However, this plant in general has a high resistance to drought, so if it rains regularly in summer, the bushes can do without watering. But if there is a prolonged drought in the summer, it will need to be watered systematically. From the beginning of September, watering should be gradually reduced. Please note that lime must not be present in the water used for watering and must be retained.

When the plant is watered or rained upon, the root zone should be thoroughly loosened to a depth of 8 to 12 centimeters and all weeds should be pulled up.

In the springtime such a plant needs nitrogen, and from the beginning of the second half of the summer period - phosphorus and potassium, this must necessarily be taken into account when choosing fertilizers. In spring it is necessary to pour under the bush a solution of urea (30 grams per 1 bucket of water), and before the plant blooms, it should be fed with a solution consisting of 1 bucket of water, 60 grams of superphosphate and 30 grams of potassium sulfate. The third feeding will be needed only when the bushes will develop relatively slowly. For this purpose 300 grams of wood ash should be evenly distributed on the surface of the bedding circle.

Repotting

The rockery shrub can be repotted if necessary.

This procedure is similar to primary planting. First you must prepare a planting hole that should be a couple of times the size of the knapweed root system. At the bottom of the pit it is necessary to make a good drainage layer. Before removing the bush from the soil, it is necessary to prepare a nutritive earth mixture, which will fill the planting pit. To do this, the soil should be combined with fertilizer.

The dug up plant is moved to a new place, then the root system together with a root ball is placed in the prepared pit, then the free place is filled with earth mixture.

Raturation of knapweed

Ruscus: planting and care in the open field, species and varieties with photos

The seed and vegetative method (green cuttings and grafts) is used for propagation of knapweed. Seeds are taken from mature beans in August/September. For sowing, a soil mixture consisting of peat and sand (1:1) is used, and the seeds should be deepened by 0.5-0.

6 cm. A container with seeds from above should be covered with a film. It is moved to a shady and warm (19-21 degrees) place, and the seeds should be systematically aired and watered (sprayed). Seedlings picking on individual pots, in cross section reaching 70 mm, made during the formation of their one or two true plates. During the picking, use a soil mixture consisting of sand, sod soil and humus (1:2:1).

In the spring, transplanting plants in larger pots, across reaching 11 centimeters. Then spend their pruning, so that the bushes were more lush. Transplanting seedlings into open soil is made in the third year, and young bushes should reach a height of 0.3 to 0.55 m.

Barking plants are prepared in summer time. For this purpose, half-timbered shoots should be cut from an adult shrub, each of which should have 2 or 3 leafy plates. Leaves should be shortened by ½ part, then they are planted in a substrate consisting of sand and peat, and the container from above should be covered with a transparent cap. To ensure that the cuttings properly rooted, they need to provide a temperature of 18 to 20 degrees, they also need systematic ventilation and spraying with a sprayer. After 4 to 6 weeks, when the cuttings are rooted, they should be transplanted into individual pots, reaching a cross section of 80-90 mm.

Cultivation in the open ground of such plants shall be made only after 2 years. To do this in the spring time, you need to select the branches located at the very bottom. They should be placed in the boles made in advance under the bush, fix and fill with soil. Throughout the season, the branches should be watered. During the feeding of the parent bush, fertilize the offshoots as well.

They should be thoroughly covered before winter, and in the springtime the offshoots should be cut off and set.

Wintering

Ruscus: planting and care in the open field, species and varieties with photos

When the bush blooms, its branches should be cut off to the strong side branches, but try not to touch the woody part. In deep autumn, when the cold weather arrives, young shrubs that are less than 3 years old should be covered for the winter. The fact is that only mature plants are highly frost-resistant. Shrubs should be dipped in dry peat or soil, then the branches should be carefully pulled down, tied and slowly bent to the surface of the site, and then fixed in this position.

Shrubs should be covered with spruce paws, dried leaves or covered with fleece covering material, while its edges should be pressed to the soil surface with bricks or stones. The adult knapweed does not need to be covered for the winter.

Diseases and pests

The knapweed has a high resistance to pests and diseases. However, moths or cocklebur moths can infest the shrubs. As soon as you notice that a moth has settled on a plant, it should be sprayed with Chlorophos.

To get rid of moths, the shrub should be sprayed with a bacterial insecticide.

The greatest danger to this shrub is powdery mildew and black spot. If the knotweed plant is affected by powdery mildew, a whitish-colored coating is formed on the surface of the shoots and leaves. In early spring, sick plant should be treated with a solution of copper sulfate (5%), doing it before the sap starts sowing. In summertime, bushes are sprayed alternately with colloidal sulfur, Fundazole solution and copper-soap liquid to prevent black spot in the beginning of spring, bushes are treated with iron or copper vitriol solution.

In summer time Fundazol, Bordeaux mixture, copper chloroxide, Captan or any other fungicide preparation of similar action will help to get rid of the disease. To treat bushes on the leaves, the solution should be prepared by strictly following the instructions on the drug.
