Hope that you have a 6 ft fence...........I am suspecting deer & or racoons are visiting you during the night..................mix 1 qt water 2 tablespoons dawn & 5 to 10 drops of hot sauce.....might need more.......................spray after the sun passes & the plants cool off..................we have 2 area of planted things both with 6 ft fences.................and short fine fence at the bottom with slate turned sideways to keep the small rodents out.
