Each year I plant a small four foot by four foot vegetable garden. This year I'm squeezing 4 tomato plants (hopefully 4 different varieties) and about 6 cucumber plants into this small area. I know it's less room than recommended but I always do it.
In the past the deer used it for a "salad bar". I tried a mini electrified fence which worked but the orange extension cord looked out of place. The chance that it would be run over by a lawn mower if I did not disconnect it in time was not worth the risk.
I tried metal chicken wire strung out into a 4x4x4 cube. The cube turned into a dented box. It looked terrible.
Now I'm trying a four sided design. Two sides are fixed and two sides are removable. If needed I'll put a soft plastic net over the top at night when the plants grow high.
Here is the layout. I've weeded three out of the four quarters. The pile of weeds is to the right bottom of the photo.
While weeding the last quarter I noticed how good the weeds looked! It was beautiful once I had a closer view. The photos are not as sharp as I'd like but I was balancing on unsteady ground.
