When you use that upside down cage, how do you stake it to the ground?
I have one small tomato cage that I use on my smaller clump of lobelia and it works well. But my other old cages are too tall- Maybe 4 or 5 feet when installed in the ground. It doesn't look good. I have no idea where I got that little tomato cage, but it's been floating around my house for years. I never see that size in stores.
Those cages never worked for my tomatoes. The pyramidal shape lets them be easily be blown over, taking the plant with them. I tried square tomato cages for a few years- they stood better, but only lasted a couple of years then fell apart. Last year I bit the bullet and bought some Texas tomato cages - now they're some real tomato cages!
