For organic container gardens, use a manure 'tea' to water and fertilize. Perhaps that is what is wrong with the cactus-mix plants. We had a fair amount of rain this spring, and it pretty much washes right through the cactus-mix. What do you think about the slow-release pellets like the ones miracle grow sells? While we are on the subject of fertilizer, I read that habs in particular can use some calcium. Non of the fertilizers I've read list any calcium. Is there a good place to get some calcium to add? > Nels in ND
