You know, if someone designed an affordable cage that would actually stand up to the NEEDS of a tomato plant, they'd make a tidy fortune. My go-to solution for tomatoes is cattle panel. It is indestructable, only requires staking to keep it where you want it. 2 panels placed parallel will give you 16' of tomato trellis 50" high. The only draw back is that it's a beast to transport. The last time I bought panels, I forgot to stake them down in the bed of the truck, and they blew out and went rolling down the highway like a giant tumbleweed. Good thing there was no traffic from either direction. I could have killed someone! I think I've finally figured out how to secure them from that incident!
Labels? Bread tabs. Can be written on with sharpies, then they are a cinch to clip onto those flimsy, worthless tomato cages... or the cattle panels. I have both in my garden right now. Need to get the cages staked before the plants put on some serious size.
I did some weeding today, and discovered some cabbage seedlings. I knew they were there, but they just kind of disappeared!
