So, how to plant a healthy and beautiful hollyhock, soil, sunlight, temperature, water, fertilizing, and pruning all require attention, and there are also some precautions. I will explain in detail below.
I. Cultivation Methods
1. Soil
Hollyhocks do not have high requirements for soil. If conditions allow, you can use soil rich in organic matter for cultivation, and loose, fertile soil with good drainage is an ideal choice for hollyhocks to take root.
2. Sunlight
Hollyhocks enjoy sunlight and can be placed in areas with direct sunlight exposure, such as balconies. However, it is important to provide shade for hollyhocks under extreme sunlight conditions in the summer.
3. Temperature
25°C to 30°C is the most suitable temperature for hollyhocks to grow and develop. Although hollyhocks are cold-resistant plants, their flowering will be affected when the environmental temperature is below 17°C. Therefore, it is necessary to create a comfortable temperature environment for them.
4. Water
Follow the principle of watering a small amount multiple times to maintain the moisture of the cultivated soil, but control the amount to avoid waterlogging, which may affect the growth of the plant. During the growing period of hollyhocks, you can increase the watering frequency to promote their growth and development.
5. Fertilizing
Hollyhock seedlings are suitable for liquid fertilizer, preferably nitrogen fertilizer, once or twice during the growing period. When flower buds appear on the plant, you can switch to phosphorus-potassium liquid fertilizer, also applying it once or twice, avoiding over-fertilizing or under-fertilizing.
6. Pruning
You can do appropriate tip removal on hollyhocks in the spring, mainly on the main stem. It is also advisable to剪除 weak and diseased branches and leaves with poor growth to promote better growth.
II. Precautions
1. Hollyhocks are easily invaded by red spiders, so it is important to pay attention to the growth condition of the plant. If pest infestations are found, they should be dealt with promptly, and medication may be necessary.
2. To make the plant shorter and more suitable for ornamental purposes as a potted plant, you can perform root pruning. The more times this is done, the shorter the plant will become.
3. It is important to regularly loosen the cultivated soil and remove weeds to promote growth.
