Herbal hibiscus - an ideal view for the regions of the middle zone with frosty winters. Thanks to the deep, powerful rhizome, which absorbs most of the nutrients, the culture calmly tolerates minus temperatures. It is enough to cover the basal zone, so that the plant safely overwinter. If the root is injured by carelessness, the whole flower dies off.
Despite the unpretentiousness of the plant to care, when growing, observe the main agrotechnical measures:
- For active growth and abundant flowering pick up the illuminated area, protected from wind-through. It is important to protect the plant from overheating. When planting, they take into account a rather high growth, therefore they are placed in the background of garden plantings or in the center. It is possible to receive a live flower fence by disembarking with an interval of 3-4 meters.
- There are no strict requirements to the ground, but usually they are loose, fruitful and with good drainage. Hibiscus does not tolerate increased acidity and excess lime. For the health of future plantings recommend making rotten needles.
- A hole is dug more so that the root system feels free. If at the place of growth the earth tends to freeze, the roots deepen more strongly. Otherwise, it is not necessary to resort to such manipulation. Pre-poured into the hole recharge - humus and river sand, richly moisturize. Saplings removed from the temporary container with a clod of earth. In order not to injure the root, gently roll over into the hole. After the powder is watered and slightly shaved.
- Transplantation is carried out in spring or autumn. Young landings are subjected to this every year. Older plants are transplanted no more than once every 3 years. However, you should be in time until the stem has stretched more than 10 cm.
- Trimming is not included in the list of mandatory care activities. If you want to get better branching and pomp in the spring pinch the tops. Before frost stalks are cut under the base.
- Due to the possible growth of hibiscus will require a vertical support.
Young plantings do not need frequent watering. Moisturize as needed - depending on weather conditions and age. In drought, the need for water increases, but does not allow stagnation. Constant monitoring of the state of the flower to let you know when there will be another need for water. When thirsty plant begins to throw off the leaves and buds. In the heat sprayed, but only after sunset.
Feed up throughout the growing season. In the spring make organic, in the fall - wood ash. Periodically carry out foliar feeding - liquid fertilizers are sprayed on the ground component. The leaves in this case are saturated quickly and fully.
From the middle of summer they begin to gradually prepare hibiscus for winter. Nitrogen supplements are canceled. After completion of flowering, pruned stems are not recommended immediately. It is necessary to wait for the period until the upper part will transfer the accumulated nutrient reserve to the root system. Sand is added to the soil and spuds are raked in high heaps. After self-drying, the peduncles are removed. To protect against frost fit any plant component: sawdust, straw, foliage. The mass is spread over the roots in such a way that there is a possibility of free access of air inside. A covering material is put on top, a snow canopy is installed.
In early spring, the protective structure is removed, the film over the vegetation in case of sudden night frosts. The first shoots pinch - then the trunk will begin to branch intensively.
Breeding hybrid hibiscus
Grassy hibiscus propagates by seeds, cuttings and dividing the bush.
Place the stratified seeds on a wet paper towel and leave at room temperature for 5 or 7 days. When the seeds are swollen, spread them out in a wide, shallow container with a soil mixture at a distance of 0.5 cm, lightly sprinkle with earth and pour. Then cover the container with glass and leave in a bright and warm place. The first shoots will turn in about 3 weeks. When sprouts will get two sheets, they can be seated (ripped out).
Cutting is carried out in early summer or autumn. At the top of the bush, you should choose a healthy shoot, cut it at an angle, remove the lower leaves, leave the upper ones. Before planting, put the cutting in the water. Prepare a large pot (not less than 1 l), fill it with soil and water well. Next, you should make a groove up to 5 cm, dip the cutting in it, sprinkle with earth and water again. Now you need to build a greenhouse around the cutting and put the container in a warm, bright place (without direct sunlight). In general, it is grafted the same way as a home hibiscus:
