Three plants produce as many tomatos as we can eat. The problem is they all ripen in about 2-3 weeks, then they're gone. This year I'm really getting aggressive and planting 6 or 9 plants, staggering them by a few weeks to try and have ripe fruit for a longer period.
I can tell when you talk about 150' of wire, you are leaving my idea of a big tomato crop in the dust. I will probably just buy a few more ready made cages for the few more plants that I buy. Post a picture of what you finally make, so I can see what I'm missing.
