Paphiopedilum cultivation methods and precautions

1. Maintenance methods

1. Temperature: Paphiopedilum likes warmth, but different varieties have different temperature requirements. In general, keeping the temperature between 15 and 25 degrees is suitable for all varieties. Its cold resistance is not very good and the temperature should not be lower than ten degrees. In addition, it is not resistant to high temperatures and cannot exceed thirty degrees.

2. Light: Paphiopedilum does not like strong light, but it cannot be completely dark either. During its growing season, it is more appropriate to place it in semi-shade, and a little scattered light can meet its requirements. In winter when the light is not too strong, you don't need to provide shade, just place it in a well-lit location.

3. Watering: Paphiopedilum likes a humid environment. During the growth period, sufficient water is needed. Generally speaking, it needs to be replenished every two or three days in spring and autumn. In summer, it is necessary to replenish water in time, generally watering once a day. Do not water too much in winter, just keep the soil from completely drying out.

4. Fertilization: Fertilize once every half a month in spring and autumn, and compound fertilizer is more effective. Generally no fertilizer is required in summer and winter.

2. Breeding techniques

1. Reproduction: Division is commonly used. Choose a healthy plant with more than six leaf clusters as the mother plant. Division can be carried out during the dormant period of the plant. After removing the mother plant from the pot, remove the substrate at the root system, but be careful not to damage the tender roots. Use a knife or other tool to divide the plant into three parts, and then plant them separately. After planting, place it in a cool and slightly humid location.

2. Repotting: Try to change the pot once a year. It can be done in April and May, or it can be carried out together with division propagation. You need to choose fertile, loose soil with a pH of 6 to 6.5, such as leaf mold with sand, vermiculite, etc. After repotting, place it in a cool place.

3. Problem diagnosis and treatment

1. Diseases: Diseases that harm leaves, such as "leaf blight", may occur. These diseases occur more frequently in summer. It can be treated with thiophanate-methyl or carbendazim. At the same time, timely ventilation is also required.

2. Pests: In winter, if it is placed indoors and not ventilated, scale insects may appear. They can be removed with the help of tools such as brushes, but if the number is very large, insecticides will be needed.
