|Which food is best for feeding cactus..I have a collection of different types and would like to know when and if they should be fed?|
|Cacti and Succulents need regular feeding during their growing season (Spring-Summer). They need a balanced range of minerals. Potassium (K) to encourage flowers and fruit, Phosphorus (P) for good root growth, and Nitrogen (N) for vigorous top-growth. Cacti also need other trace elements.
Cacti and Succulents require feeding in two different stages. Add powder or granular fertilizers to potting mix during planting time. Thereafter apply liquid, or solid fertilizers throughout the growing season. Fertilize cacti half as often as the plant is watered. Cacti and succulents respond well to liquid fertilizers consisting of 15% nitrogen, 15% potassium, 30% phosphorus, and all of the other trace elements.
