I'm growing all my tomatoes (18 plants) in 5 gallon food-grade buckets this year, and they're the best looking and most productive I've ever had. The first ripe tomato was harvested yesterday (Costoluto), and Sioux and Ozark Pink are next. I have two Cherokee Purple that I grew from saved seed, and each plant has 9 tomatoes. They're in my top 5 favorite tomatoes and I've never had them produce so well--I usually get only one or two a year--so this is an exciting change in their "behavior". A good growing year so far.
