Caging Your Tomatoes?

Apr 23, 2018

Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County


Client's Request: Do you have recommendations on tomato cages? I bought the heavier gauge tapered cylinder ones at the “big box store”. Even though they are sturdy the bigger heavier tomato plants tipped them to the side. I then built wood ones out of 2 x 2 and 1 x 2 and they were sturdy but rotted after two summers in well-watered soil. Ideas?

MGCC Help Desk Response: Thank you for contacting the UC Master Gardener program with your question about tomato cages.

Those big indeterminate varieties can get quite unwieldy! If the wire cages you have are big enough, you could try tying them to a (e.g. re-bar) stake firmly anchored in the ground to stop them falling over.

But, but if you want something more hefty, my favorite (and what we use at the Master Gardener demonstration garden) are made of concrete reinforcing mesh. This generally comes in a 5 ft. width, tall enough to roll up into a cage. You can buy a roll at most home improvement stores - sometimes you can find flat pieces, but I have not found any that are big enough to make the cage. As for how to make them, a Google search will come up with a number of sites giving clear instructions. I use heavy duty zip ties with a one square overlap to connect mine - that way I can cut the ties and store them flat at the end of the season.

Buying a 50 or 100 ft roll of this stuff seems like a lot, but if you grow a number of tomato plants it is quite inexpensive, and I have found the wire also very useful for trellises, etc. It is not the easiest material to work with, you need a heavy duty wire (or bolt) cutter and some space to roll it out and wrestle into shape! Maybe a joint purchase and construction project with neighbors and/or relatives might make this a more feasible project. If you only grow a few plants, an online search for 'heavy duty tomato cages' will bring up some other options.

One other tip - I have found that tying the cage to a re-bar stake prevents any toppling over, and these stakes last for many years.

I hope this helps, and good luck with your garden, and tomato growing!
