Culture methods and matters needing attention of hollyhock
Hollyhock, also known as Yizhang Hong, is a biennial erect herb of Malvaceae. It is widely distributed in our country. Hollyhock is highly ornamental. It can be used not only for landscaping, but also for pot cultivation. And roots, flowers, leaves and other organs can be used in medicine, with a lot of efficacy. So how to raise hollyhocks? The following editor brings you the breeding methods and matters needing attention of hollyhocks, let's have a look!
1. Soil selection
Before raising hollyhocks, we first need to choose the soil. Although the requirement of hollyhock to soil is not very high, it has strong adaptability and can grow normally in saline-alkali soil. But the quality of the soil will determine the growth of hollyhock, so we should choose a soft, fertile soil with normal drainage and irrigation and rich in organic matter for cultivation. A suitable soil is very important for the growth of hollyhock, so we must pay more attention to it. Then we have to deeply disinfect the soil and apply sufficient base fertilizer.
2. Planting management
The growth ability of hollyhock is strong, so management is not very difficult. When the seedlings of hollyhock grow to about 2-3 true leaves, it is necessary to do a good job of seedling work and expand the row spacing. The seedlings were properly watered after transplanting, and then ploughed and weeded once before flowering, and topdressing about twice. Fertilizer should be based on phosphorus and potassium fertilizer. During the seedling growth period, we should also apply an appropriate amount of liquid nitrogen fertilizer. And often loosen the soil and weed to ensure the normal growth of hollyhocks. In order to prolong the flowering time of hollyhock, we should keep plenty of moisture. After the flowers have withered, the aboveground parts are cut off to promote the germination of new buds.
3. Water and fertilizer management
When planting hollyhocks for management, the most important thing is the management of water and fertilizer. In the process of planting, we should pay attention to watering regularly to maintain a moist environment. Provide sufficient water for the growth of hollyhocks, but pay attention to control the amount of water, not too much, to prevent hollyhocks from waterlogging. And just said, in the flowering period should be more watering, increase the number of flowers, prolong the flowering period. When applying fertilizer, not only sufficient base fertilizer should be applied, but also liquid fertilizer dominated by nitrogen fertilizer should be applied twice during its growing period. After the formation of flower buds, the liquid fertilizer mainly composed of phosphorus and potassium fertilizer was applied twice.
4. Points for attention
Hollyhock is a kind of light-loving plant, so the first thing we should pay attention to is to maintain an environment with enough light. In addition to summer, hollyhocks can be exposed to direct sunlight, but in the summer strong light season, we should pay attention to shading the sun to prevent leaves from being burned by the sun. The suitable growth temperature of hollyhock is about 25-30 degrees, and the best temperature range is 26-28 degrees after entering the flowering stage. If the average monthly temperature is less than 17 degrees, it will affect flowering. Therefore, we must pay attention to control the temperature, but the underground part of hollyhock has strong cold resistance and can survive in the open field in winter.
The above is a brief introduction of hollyhock culture methods and matters needing attention. That's all for today's introduction. This article is for reference only. I hope it can help you all.
