Since I'm cutting way back on my tomato plants this season, I think
I'll try a different method to support the plants. I use the green
steel fence posts that you buy at any hardware store 5' tall. All the
other years I used a single stake per plant which worked ok but constant
tying here and there is necessary and some branches still break due to
the weight of the fruit. Since I'll have an excess of fence posts this
season, I plan to put 3 stakes around each plant in the shape of a
triangle. I'll run parachute cord from stake to stake at several
different heights. It should work kind of like a tomato cage except
much stronger as each stake will be a foot or more into the ground and
the cross members will be of parachute cord and not wire. Each stake
forming the triangle, I'll place eight or nine inches from the plant.
By doing this, I think that I may be able to get as big a harvest even
though I'm setting out half the amount of plants. When using a single
stake, I would prune the plant in order to have one or two main stems.
I should now be able to allow at least four main stems per plant. I do
realize the size of the fruit may not be as large but the volume of
fruit should surpass the difference. Any opinions on this idea?
