How to Care for the Plant
Water
Moss rose plants are drought and heat tolerant. In a flower garden, watering is seldom needed. If growing in containers or hanging pots, allow a soil to dry between watering.
Pruning
Make judicious cuts to encourage new growth. Cut just before a leaf node. Or when cutting back larger stems, cut as close to the main stem as possible.
Fertilizer
Use a balanced fertilizer with a 10-10-10 formula.
