Growing Tomatoes in Bags
I've found a number of articles on the web about people growing veggies in reusable grocery bags. I understand that they may biodegrade over time, but I'm hoping they will hold up for one season. I'm also considering poly grow-bags, but I'm not sure if those will work outdoors for an entire season either. Any advice on the bag idea would be great - I can't afford a slew of large pots and my dirt is basically sand, so I have to grow in containers.
My more pressing question is that I mostly like growing heirloom tomatoes. I will likely have 10-20 plants this coming year (if I don't go crazy and end up with a yard-full of bags!) I have a few questions about support for the plants. I can do cages at just under $3 a pop, or I have access to wooden stakes. I'm really thinking that ideally, I would love to just have smaller, bushier plants. Here's the dilemna though, I want them to be indeterminate. I want it all! LOL So - can I top-cut an indeterminate and will it still continue to bush (put on productive suckers) to keep it short, or will it just end up sprawling without some kind of support? Are there heirloom bush varieties that are indeterminate, or do I have to stagger some determinate plants to get spaced out harvests?
I was thinking I had to give up gardening for this coming year and now I'm re-excited after finding this bag idea. Any help or thoughts are much appreciated!
