Hi have plants that like good drainage was going to use john innes no 3, and grit should i add sharp sand as well and if so what mixture. thanks
Depends on your plants and what you mean by "good drainage". Often plants are described as needing moisture and good drainage!! Adding grit....perlite is better....to compost or soil will help drainage. For example, I have a tender euryops sub shrub that needs sharp drainage and I've used 50/50 mix in a terracotta pot.
Good morning Verdun, I am going to plant ferns, bamboo,cordys, palms, fatsia and euphorbia martinii. many thanks
Ah the old "moist well drained soil" i often wonder if anyone actually knows what that means, as it appears on just about every plant label you ever buy.
Well if anybody does know can they please tell me!
