tomato cages, inserted in a rectangle pattern in your garden (w/ a plant in each of the 4 corners and wire cages. Then take plaster garden netting (4-ft tall rolls, green in color), and wrap around the whole enclosure/rectangle sq. of wired 4 tomato plants. Cut to length the 4 foot green netting to the same length of the outside the 4 wired tomato plants. Fashion or tie with twistees the plastic netting to the firmly into the ground 4 wire tomato plants. If enough room left between the 4 sides between the wire tomato cages, plant more plants.

This worked for me, w/ four big plants in a 6x4 ft. garden area I had, didn't have to keep adjusting the four wire tomato cages w/ their 1 plant each x 4.

I hope not too confusing. Kind of like a cage within a cage. Good luck.

Costs money but well made.
