- Over time, the soil loses some important properties. The plants should therefore be transplanted into a larger pot with fresh container plant soil every two years in spring.
- Frozen shoots should be cut back to the healthy wood as soon as there is no longer any risk of frost.
- A slow-release fertiliser can be used in spring. This releases the nutrients slowly and continuously so that the plant is evenly supplied over a longer period of time.
- Watering less frequently, but thoroughly and thoroughly, encourages the plant roots to penetrate deeper into the soil. This enables the plant to survive dry periods better.
