Tomato ring culture

Thanks for the feedback. I can understand the principle of the bottomless pots on a solid base or even growbags. I was just musing whether the faff of using them on a deepish border would yield any benefit. I suppose the only way to find out is to try it next year on two similar plants. That does require a rather scientific approach, which is unlikely to happen. I expect if the fyba pots rear their head at planting time I'll give it a go, otherwise they'll end up into the black hole that is my shed.
