How to grow lily and azalea

1. Maintenance methods

1. Temperature: It prefers a cooler climate. Generally speaking, 15 to 20 degrees is more suitable. Extremely hot or stuffy environments can cause some degree of damage to it, so once the temperature is above 30 degrees, it needs to be adjusted as much as possible.

2. Light: There are certain requirements for sunlight, but exposure to the sun is not acceptable. During the growing season and when it blooms, it needs to supplement sunlight in time. When encountering strong light, shade is needed. In addition, maintaining sufficient light during the winter is also helpful.

3. Watering: Because the roots are hairy and relatively small, they have certain requirements for water quality and need clean water. In addition, you must also pay attention to the amount of watering and avoid excessive watering, otherwise the roots will easily rot.

In addition, be sure to cut off some of the leaves to prevent them from consuming too much water. It can also be treated with various rooting powders. Choose humus or other types of acidic soil as the substrate. After insertion, keep the temperature between 20 and 25 degrees, provide shade, and ensure humidity.

2. Pruning: Pay attention to the pruning of its branches at ordinary times. The most important task in spring is pinching. Other branches and leaves, such as dry and yellow, should be pruned in time. After flowering, proper pruning should also be carried out.

3. Problem diagnosis and treatment

1. Disease: A common disease is called "leaf swelling disease". If it occurs before the shoots emerge, Bordeaux liquid can be used for prevention and control, usually once every week or ten days. There is also "leaf spot disease", which also threatens the health of leaves. Class A thiophanate can be used for prevention and control.

2. Pests: Common pests are aphids, which can be controlled by copper sulfate and omethoate solution.
