Toothed buzulnik is ideal for mixborders
You can get new seedlings of toothed buzulnik by dividing the bush and seed method. In the first case, you need to dig an adult bush in early spring at the beginning of the growing season. After that, clear the roots of the earth so that the recovery buds are visible. Using a shovel or a sharp knife, divide the bush into parts, each of which should have 2-3 shoots and the same number of root processes. At the end of the procedure, you need to drop the delenki to a permanent place.
Important! You can plant a plant at least 5 years old.
Growing from the seeds of the buzulik serratus also does not pose any difficulties. To do this, you need to collect planting material at the end of October and plant it in the ground before winter. So the seeds will undergo a natural stratification and will spring in the spring.
If you wish, you can grow young seedlings in seedlings. For this, it is necessary to plant in wide bowls in January, and then put them in the vegetable section of the refrigerator for 1.5 months. At the end, put the containers on the windowsill. Transplanting seedlings in open ground should be done in September.
Toothed buzulnik can be planted from May to September under favorable conditions. For this, you should choose biennial plants, as they easily adapt in a new place.
Buzulnik gear well develops in partial shade. The plant also prefers drained soil rich in organic matter. Therefore, 2 weeks before disembarkation, you need to dig the site and make humus at the rate of 10 kg per 1 in. m. You should also prepare a planting pit 40 by 40 cm in size and fill it with 2/3 of the volume of the nutrient mixture of turf, peat, leaf soil in a ratio of 2: 1: 1. In addition, add 30 g and 100 g of wood ash to each well of superphosphate, and then mix thoroughly with the ground.
Algorithm of actions:
- Make a slight elevation in the center of the landing pit.
- Put a seedling on it so that the recovery buds are at the level of the soil.
- Spread the roots gently.
- Fill the voids with earth, compact the soil surface.
- Water the plant abundantly.
Important! When planting several copies of the caterpillar in the same row, a distance of 1 m must be observed.
This plant is undemanding to care and therefore does not require increased attention. But in order for the toothed buzulnik to fully develop and bloom profusely, you need to adhere to simple rules.
Watering and feeding
Soil moisture is very important for this crop. With a lack of moisture, the plant will not die, but its decorative qualities will decrease. Therefore, watering should be carried out regularly in the absence of rain, preventing the roots from drying out.
Important! It is recommended to feed the toothed buzulnik during the period when not only days but also nights will be warm, otherwise this will not give a positive result.
Organic fertilizers are best used. To do this, you should breed a mullein 1:10 or chicken droppings 1:15. In their absence, you can use mineral mixtures. During active foliage, it is necessary to use urea or ammonium nitrate at a rate of 30 g per bucket of water. And at the time of formation of the peduncles - superphosphate 30 g and potassium sulfate 15 g per the same volume of liquid.
Weeding and cultivation
After each irrigation, the soil in the root circle should be loosened to improve its aeration. It is also important to remove weeds in a timely manner so that they do not pick up nutrients.
With the onset of frost, the aerial part of the plant needs to be cut off at the base. Then lay on top a layer of mulch from humus or peat 5-7 cm thick. Such a shelter will protect the root of the buzulnik in the event of a snowless winter.
Diseases and Pests
This culture is highly resistant to pests and diseases. But in conditions of high humidity over a long period, the shrub can suffer from slugs. To protect the plant, you need to sprinkle at the base of the bush with wood ash or granular superphosphate.
Slugs feed on young buzulnik leaves
Also, with a combination of high temperature and humidity, the caterpillar can suffer from powdery mildew. It is easy to recognize the disease by a white coating on the leaves, which subsequently becomes dirty gray. This leads to wilting of the plates. For treatment, Topaz or Skor should be used.
Planting and caring for the serrated buzulnik are not difficult even for beginner gardeners, so the popularity of the culture is growing every year. This is also facilitated by the fact that a perennial shrub can fully develop and bloom where other plants do not survive. Therefore, it will turn out to be used to ennoble shady places on the site.
