First, how to gain weight 1, light: it likes places with dry weather and plenty of sunshine. Especially in summer, when there is a lot of rain and the weather temperature is high, it will grow faster and better, but this is a strong light, so it should be shaded, but the illumination time should be guaranteed for about 4 hours every day.

2, moisture: more rain in summer, it will rise better, resistant to damp heat. The requirement for moisture is relatively high, and generally, the soil is partially dry before being watered completely. This will help it grow better.

3. Temperature: 25℃ is generally suitable. Especially in summer, when the weather is hot, it grows better. When the temperature is higher than 35℃, it is necessary to reduce the replenishment of water. Don't be below 10℃ in winter, otherwise it will affect its normal growth.

4. Soil: It is a relatively drought-resistant plant. Just use garden soil for maintenance to meet its growth needs.

Second, how can there be red claws? This red claw can exist for a period of time, but it does not exist forever. We can change the environment to create conditions for it. Spring and autumn are its growing periods, which are prosperous and can give enough sunshine and time. Pay attention to shade it in summer. In addition, the greater the temperature difference between day and night, the more likely it is to appear red claws.
