If they went down that fast.. it was grasshoppers & or pill bugs (aka-rollie pollies). They are both mean ass little bastards with a serious hunger.
.
Go buy some really cheap hot sauce. The $ 1 a bottle kind, mix two ounces of your hot sauce with one gallon of water. Mist the area all around where you intend to grow.
.
Don't do it if the wind is blowing, cause smoke is not the only thing that sucks to get in your eyes. Wait a few days, go back & prep your holes for planting.
.
Don't put plants, smaller than a foot in the great outdoors - bugs will get small plants, because they are soft & tender. The hot sauce will run them off, follow that up with some Prytheum (all organic / non-toxic to humans) Powder. Most garden centers have it. It's a dust, comes in a cardboard (shake it out type) dispenser. Use it weekly, dust the ground from the main stem outward two feet. It will kill your pests - stone cold dead....

Hope this helps..
Keep it Real....Organic......
