Watering and Fertilizing the Plants

It is critical to keep Dark Knight well-watered during its first year of development.The drought-tolerant nature of these plants means that they do not need much more watering after they have been established.

It is preferable to feed these plants with a side dressing of organic compost rather than using fertilizer on a regular basis. Excessive fertilization promotes leaf development while inhibiting the generation of flowers.

Soil and plantation techniques
