Cactus potting mix for seed starting?

Greatgardens · February 18, 2023

I've tried the usual suspects for starting tomato seeds, but I nearly always have issues with the plants being over-watered. The problem seems to be that the mix is dry at the surface, but still wet on the bottom. By the time the plants are about a month old, they are starting to suffer.

I thought I'd try a few plants this season using cactus mix. This is a sandy mix with a little peat and perlite in it. I'll also add a small amount of Tomato Tone dry fertilizer. Has anyone done something like this -- what were your results?
