Growing a flower: how to plant it in open ground

The plant must be grown in a well-lit area in the morning and evening, and in the afternoon it must be in partial shade. This will allow the flower to remain without burns from the bright sun. The rose is planted on a hill, where there will be no accumulation of moisture, leading to rotting of the plant root system. The place for planting the bush must be ventilated and protected from drafts and strong gusts of wind.

A rose requires a fertile, moist, loose soil with high acidity. The composition of the soil must be nutritious. You can make a nutritious soil mixture yourself. To do this, you need to mix:

• 3 hours of manure;
• 2 hours of fertile soil;
• 2 hours of sand;
• 1 tsp peat.

The seedlings must be of high quality. The presence of long and pale shoots indicates a painful condition of the seedling. Good seedlings should have:

• developed root system;
• strong stems of bright green color;
• not less than 2-3 lignified stems.

Selected seedlings are prepared in advance before planting. They are kept in moist soil in a cool room, soaked in a growth stimulator.

Planting a Blue Nile rose

Planting in open ground is carried out from March to October. This is best done in the spring. At the time of planting, the ground should warm up to 12 ° C. Step by step scheme:

1. Dig holes 50 cm deep at a distance of 70 cm from each other.
2. At the bottom of each, pour 10 cm of a drainage layer of pebbles, sand and broken brick.
3. Put a layer of prepared soil mixture in the pits, moisten.
4. Plant rose seedlings, gently straightening the roots.
5. Cover with nutritious soil, tamp and water abundantly.

Plant care

Compliance with the rules of care will provide the plant with stable growth and re-flowering. Care consists of watering, loosening, fertilizing, pruning, shelter for the winter and replanting.

Watering

Watering should be sparse but abundant. In this case, it is impossible to dry out the earth. In normal weather, 1 watering per week is enough for a flower. Each bush is poured from 3 liters to 5 liters of water at room temperature. During the dry season in summer, the frequency of watering increases to 2 times every 7 days. Watering is best in the evening.

Loosening

Loosening is required after each soil moistening. It is necessary to loosen the soil of the root circle carefully, otherwise there is a possibility of harm to the root system of the plant. Loosening contributes to the saturation of the earth with oxygen and water permeability. During the procedure, the emerging weeds are removed.

Top dressing

In the first year, the plant will not need feeding. In the second year, they begin to fertilize it. In the spring it is necessary to feed with mineral fertilizers. A week later, the rotted mullein is introduced. During the budding period, the plant is fertilized with an infusion of chicken droppings and a mullein. Before flowering, mineral fertilizers are again used. Top dressing is stopped when the rose begins to bloom.

Pruning

In the spring at the beginning of March, before the buds awaken, the frozen, dried and damaged shoots are cut off from the flower. Empty and dead buds are removed throughout the summer to ensure abundant flowering. In the fall, they carry out sanitary pruning, removing broken, damaged and overly long shoots.

Shelter for the winter

Despite the plant's resistance to subzero temperatures down to -35 ° C, it needs to be insulated just in case. First, the rose is covered with dry foliage, then with spruce branches, and at the end - with non-woven material.

• improper hydration;
• lack of food and lighting;
• harmful insects, diseases.

If you follow the rules for care, transplant and feed the plant, then the hybrid will bloom.
