Interesting , keep us posted on future results. I dislike buying potting soil. I have a separate compost pile, have been doing it for years. It is just for potting soil. I only use large pots for peppers and starting seeds and cherry tomatoes. I prefer not to have them down in the bigger garden. So at the end of the summer, I dump out and compost the potting soil. I figure it’s formulated for drainage mostly. I add composted goat manure when I pot things up in the spring. It’ll be years before I deplete the goat manure. I also add any potting soil from any hanging basket or other planter bought or given to me.
Two of the tomatoes are a little puny. Going out to check on everybody this morning. I think I may have been a little rough getting one of them out of their pots.
Hope Mr. Greeneyes can return home soon.
