- Empty the saucer immediately after watering to prevent the roots from coming into contact with stagnant water.
Fertilization and manure
Fertilizing helps stimulate growth and flowering, but it is not essential if the initial substrate is of good quality.However, a light application of specific fertilizer for cacti and succulents, preferably liquid for rapid absorption, can make a difference during the period of active growth (spring and summer).
