Anyone care to tell me their experience with fertilizing cacti? And if so what fertilizers would they recommend? This is my first spring/summer with a large-ish collection.
Cacti dont want too much nitrogen as soft growth will make plants softer,i used chempak designed for cacti and succulents.
In general, if you give them the correct soil and light, re-pot them every 2-3 years, they don’t need to be fertilized at all. Usually people think about nitrogen saying fertilize, but succulents don’t need it.
