Q.Why Has My Greenhouse Grown Chard Gotten Tough And Hard?
Second question Do I need to empty out the soil used in my greenhouse this summer, before planting seeds for my winter veggies? Third question I’m in Fairfield, Iowa. When do I start seeds for winter chard, etc., and what veggies can I grow in my greenhouse this winter in addition to chard? Thanks!
