Soil for C& S trough
I started planting a new trough tonight. I used a 1:1 ratio of container soil and small grit ( 2-4 mm). I have since noticed that the the container soil contains calcined clay to 'help maintain soil humidity"...okay. It also contains peat, humus, compost, sand, and perlite (not in that order). I am now concerned this soil may hodl too much water for my shallow trough. Plants to be potted in this trough are Rosularias, a Jovibarba heuffelii, Opuntia fragilis, a Sedum dasyphyllum, an Orostachys spinosa, and a Trichocerues inermis. Trough is about 5 inches deep. I'm in coastal zone 6. I am at a bit of a loss as to what soil to put in this trough, even the C& S soil I've been able to find locally is peat=based,,
So, should I use the soil I have, or try something else?
