Good morning, Toby! My hubby got me an upside-down tomato planter last year for our anniversary from Hammecher-Schlemmer (spelling?). He does know his bride's hobbies, er, obsessions. It came too late for planting tomatoes here, but I am planning on trying it out this year. The idea is that the weight of the fruit hanging down will keep the stem straight and strong, the position of the plant will confuse pests (and the fruit is somewhat protected from the elements), and finally, that in the top part, where the roots are, you can plant herbs. I'm pretty excited about it! You probably should use a pretty rich soil for tomatoes anyway (and not one that you used for tomatoes or peppers before, because they drain certain nutrients from the soil with successive plantings).
I have some buckets tah we're going to turn into tomato growers. I wonder if regular sized tomatoes can be grown like that too? Anyway I'm going to plant marigolds on the top of the pots.
Thanks for the info. Do you hang them frowm a post or what and how high is the bucket to be from the ground.
