I've been looking in to seed saving and what it takes to separate varieties of crops to avoid cross-pollination. I think this year we will limit ourselves to just one of each variety that cross-pollinates. One watermelon, one pumpkin, etc. But peas, beans, tomatoes, and lettuce are all self-pollinating and can be grown relatively close without risk of cross-pollination. I imagine bush variety beans and lettuce would be easy to grow and transport in buckets. I'm not so sure about anything else. I know there's plenty of people who grow exclusively in buckets, but they don't typically move their buckets in the middle of the season.
I'm considering trying those fabric shopping bags as containers too. I saw some at Menards for under a dollar. They're fairly small, but would work for smaller plants like lettuce, collards, kale, or perhaps a dwarf tomato. I'm just not sure how well they'd hold up being picked up and moved. Wet dirt can get pretty heavy.
I guess I'm still at a stand still, just spinning my wheels. I have all kinds of ideas and plans, but just need to know what direction to go in and a timeline. I need a temporary project to keep me busy while I wait for answers.
