i don't have good luck planting tomatoes. this year i circled the plants with plastic screen. i ran out, and one screen is lower than the one with the lower the others (they are 3 ft high) i also have the traditional wire cage that is tapered to larger at the top. the plant that has the lower screen has the tops chewed off. my whole garden is fenced in; but something is getting in. one of the "fixes" that i have read about is soaking apple cider vinegar in cotton balls and tying them around the fence. i did that just now ( my garden is 20 ft x 20ft). any other suggestions that might help; other that posting guard????????????????
