I read that blog too, and that's when I went out and looked and posted. next time,
I will block up the bottom hole more with some plastic instead of the paper towel "collar" I put around the tomato plant when I planted it up through that bottom hole, so that it would anchor. Mine is not as leggy as hers, but I haven't had it out as long either. It was a novelty this year, and I have flowers planted up above it, so it looks quite nice anyway. I'll report back come late August.
