I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Your best option is to cover the plants with a lightweight, spunbound polyester rowcover fabric or some type of fine netting. These will protect the plants from the grasshoppers. You could also try applying an insecticide to the leaves to kill the insects. However, treating the plants with pesticide may kill grasshoppers that eat leaves, but more will simply migrate in thus rendering that option not so effective in preventing damage.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
