I checked on my spinach this afternoon and I looked at the bottom. This is what they have mold covering the bottom. I guess I shouldn’t have used the cardboard material seed starters. I should have used plastic or something else that wouldn’t mold. I’m not sure, but I’m trashing these just in case this is dangerous to eat. Not too much wasted on them. Glad I only planted a few to see how they do. I plan on waiting a few weeks during which I plan to finish preparing my garden. I measured a spot in my yard today that gets great sun most of the day. I’m going with a space that is 14 feet long by 6 feet wide. My plan is two raised beds with a small walk through in between for sitting, kneeling, working, etc.
