This illustrates why sufficient spacing is needed between each bucket and can be filed under the "What not to do when growing tomato plants in 5-gallon buckets" category. I wasn't thinking. I shouldn't even have needed to think. If I had planted them in the traditional way I would have spaced them far enough apart. You always put ample space between your plants. That's Gardening 101. Why I didn't think it was necessary when growing them in buckets, I have no idea. In time, the vines of each plant got tangled up in the vines of the plant beside it. I had been rotating them 180° each time I moved them but that eventually became impossible. As a result, the tomato plants started to lean in the direction of the only sunlight they were receiving every day. The "lean" grew more pronounced each day and two of the buckets were in actual danger of tipping over. Without being able to rotate the buckets, the only solution I could come up with was to tie a rope to the two wire cages of the plants that were leaning the worst and tie them off to the basketball goal.
