Hey guys, I'm going to buy a few cacti online this spring and I was wondering what a good general mixture is that I can use for most commonly available species?
I'm in the UK, shops near me would be Wilkinsons and B&Q.
Would a mixture of perlite, sphagnum peat moss, coconut coir and generic potting soil in some sort of ratio be okay as I already have that stuff lying around? Also I've read mixing in some bone meal is a good idea, when I'm starting out in 3" pots, how much bone meal are we talking?
Finally I've read that liquid tomato feed can be an adequate fertiliser for cacti? I'm a little confused about how often it is necessary to feed cacti during their active period (spring and summer)?
any advice would be super!
