This is how it is used:
I have six of those, but it's not enough. These days I grow at least 12 tomato plants that need supporting (as well as some bush varieties that don't). Unfortunately that model of cane-support seems to have been discontinued. My most recent appeal for help has produced these:
These ones are made by Botanico, and I bought them from Greenfingers.com. They were being sold as a set of 3 at £4.99 (plus postage). I bought two sets. I can't remember who told me about these, but if it was you, then "Thank you"!
Of course they are really designed for use with Growbags, not pots, so my biggest worry was whether the elliptical bases would fit inside any of my pots.
Well, I have tried them, and I find that they do fit inside some of my pots, but only some - the ones with square bases not tapered ones - and then only when placed diagonally.
At least this is a step in the right direction! I may decide to alter the shape of the base pieces (perhaps with a hacksaw?). I haven't tried bending them yet, but it may come to that, if it's possible. First indications are that these cane-supports will be quite good, because unlike most of the others I have tried, they are strong.
On the Down side though, this new model of support only has one ring (right at the top), whereas my favourite ones have two rings, which is better for the stability of the cane.
I shall of course report later in the year on how the new models perform...
