How to build your own sturdy tomato cage using lumber -

 I have had enough with the cheap wire tomato cages that fall over, bend and break every year.  Last year I went to buy some more sturdy ones, ones I've seen in people's yards.  Unfortunately they cost around $20 or more per cage and I couldn't justify it.  This year I have 15 tomato plants and I cannot imagine spending $300 on cages.  For that cost I can just buy organic tomatoes from the store and forget about growing my own.

Last year as an alternative I grew my tomatoes up by pinching off the suckers using not quite sturdy enough cedar poles.  If I did it again I would use metal stakes but I don't want to go buy a bunch of those either.  My grandpa gave me a couple cages, the ones he had been using for years that he constructed out of scraps.  He never throws away lumber.

This year I decided to copy his work.  I think the wood cages look really nice in the garden. They are cost effective at less than $5 for the materials per cage.

The tomato cage I have constructed is 44 inches high and 15 inches wide with 13 inches between supports.  I am very happy with the dimensions.  I made a couple cages at 42 inches high and only 12 inches between the bottom two supports for my smaller variety tomatoes but they are not my favorite cages.  You could make your cages any size you please.   Instructions here are for the 44 inch high cage.

Materials You Will Need

3 - 1x2x8
2 - 2x2x8
84 (yes, 84) - galvanized 2 inch 6d nails
Drill bit (3/32)
Measuring tape
L Square

Step 1 - Cut Your Lumber

For the three 1x2's - rungs and supports -

Line the three 1x2's up together so you can mark them all at the same time.  Using a L-Square measure and mark the following across for each board:

15" 15" 16.5" 16.5" 4" 4" 4" 4" 4" 4" 4" 4" (that's eight - 4 " - you will know you are done when you reach the end of the board.)
I mass produced and just measured as many as I could at a time. 
Use a hand saw or whatever saw you have to cut the 15 and 16.5 inch rungs and 4 inch supports.

For the two 2x2's - sidepieces -
Measure, mark and cut the two 2x2's into four 44 inch sidepieces.

You should have:
6 - 15 inch 1x2 rungs
6 - 16.5 inch 1x2 rungs
24 - 4 inch 1x2 supports
4 - 44 inch 2x2 sidepieces

Step 2 - Mark your four - 44 inch 2x2's

Line up your four 44 inch 2x2 sidepieces.

Using your L-Square measure and mark 13 inches from the bottom on all four boards.

Measure and mark 1.5 inches up from the 13 inch mark (Your first 15 inch 1x2 rung will go between those two lines).

Measure and mark 13 inches up from the last line (this will be where the next 15 inch 1x2 rung goes).
Step 3 - Assemble the first side of the tomato cage which will look like a ladder

Starting at the top of the sidepieces, nail a 15 inch 1x2 rung flush with the 44 inch sidepieces.  To make the second rung, attach another 15 inch rung just above the first line from the top of your board (15 inches down from the top).  Attach a third 15 inch rung between the bottom two lines, 13 inches up from the bottom of the sidepieces.  Repeat this with the other 44 inch sidepieces and remaining 15 inch rungs so you have two "ladders."
Make sure the "ladder" is level by placing it upright on a flat surface and then carefully keep it in place and add a 4 inch 1x2 support under each side of each rung nailing the 4 inch supports to the sidepieces.  The supports will keep the rungs from shifting.

TIP - To avoid splitting pre-drill each 1x2 every place you will use a nail.

Step 4 - Connect the two ladders
Bring the ladders together by nailing three 16.5 1x2 rungs to overlap the edge of the 15 inch rungs.  Do the same on the other side to make a square.

Make sure the cage is level and add a 4 inch support under each side of each 16.5 inch rung slightly overlapping the supports from the 15 inch rung support.

TIP - Start attaching the 16.5 inch rungs, as with the 15 inch ones, beginning at the top of the tomato cage.  It will be easier to manipulate or ignore a discrepancy at the bottom of the cage if the boards are warped or the wrong size a little.

Finish the project by pre-drilling and then sinking a nail into each 16.5 inch rung where it overlaps a 15 inch piece.
You will absolutely love your sturdy, good looking tomato cages and your tomato plants will thank you by flourishing!


  1. This is a very helpful tutorial! I'm showing this to my husband tonight. We haven't been having much luck with tomatoes staying contained.

  2. My dad made them for mom back in 1980

  3. How would you finish the wood for protection?
