Hi people, i am just wondering if any one has any good NPK ratios for cactus? Iv got them in half purlite and half compost. Also while im here- is spike loss due to a nutrient deficiency? thank you good people
I have a lot of cacti and make my own compost from standard peat-free garden compost, sand, and grit to a ratio of about 70/20/10. As for feed the general rule for cacti is either a general purpose plant food, or tomato feed at between a quarter and a half of the recommended dosage for other plants. If you go above that the cacti will become mis-shapen due to over-feeding.
Between October and the beginning of March cacti should not be watered or fed as it's their dormant period. if they're in a particularly hot room then you could give them just a little water occasionally through that period.
I has just dawned on me that you mean spine loss rather than spike loss! Duh! I was thinking flower spikes on succulents rather than spine loss on cacti!

I use tomato feed to my cactus as my own feed is to smelly for indoors
When I grew cacti and succulents years ago, I fed them occasionally on Phostrogen. I think spike loss might refer to succulents rather than cacti?
i like to make my own mix of feed, ill have to have sneak peek at the cactus feed bottles,lol,
the spike lose is just on some old cactus down the edge's,,its far from a problem, maybe its just old age?
