He got a few 4 gallon plastic buckets; he packed them with dirt and compost to make the planters, cut a hole at the bottom of each to insert a tomato seedling in through, put in a little bit of wet newspaper as packing around to anchor it, and then hung them upside down on steel hooks and chains strung around his backyard. It was about the best crop he had had in a long time. The preserves and sauces he made, (I got a bottle of it) were pretty good. I'd always encourage him to try newfangled gardening ideas like this if it could net me a great bottle of its yield.
Reverse gardening like this works great with certain kinds of plants - cucumbers, peppers and of course tomatoes. The popularity of upside down gardening could be attributed in part perhaps to the way topsy-turvy planters are there to buy at Wal-Mart and every other big box retailer. Upside down planters are really catching on at Bed, Bath and Beyond, Gardener's Supply and other gardening providers. It's a concept that's totally of its time. So what exactly is it that inspires people to accept gardening ideas like this? To begin with, it does fine for a small home; it needs almost no space, cages or stakes. Weeds don't like it up there, and garden pests seem to not tolerate the novel position. It gets better water and air, and it's impossible to over-water.
It's almost impossible to go wrong with upside-down gardening. You'll find that tomatoes and jalapenos, two garden plants that are difficult to get the thrive in a regular right side up garden, are effortless to get to take root upside down. They even seem to grow bigger and more robust this way. When I tried topsy-turvy planters myself, I didn't seem to get anywhere; they are made of plastic bags and somehow my tomatoes never seem to prefer them. When I used plastic buckets nailed to posts around my back porch, and planted herbs at the top for moisture record retention, my tomatoes did very well. Perhaps the reason for that is that Topsy-Turvy uses perforated plastic bags; and they can dry the earth out really quickly. But I found that large-yield tomatoes don't really work well hanging upside down. They're just too heavy for the little vines to support.
If you get creative with your gardening ideas, you can use just about any kind of container, or an unperforated plastic bag. Look up upside down gardening ideas on Youtube, or Upsidedowntomatoplant.com for more ideas.
