Sounds crazy, but take a few plastic Kroger shopping bags and go to Master Cuts or whatever, ask kindly at the end of the day if you can have some hair. Usually they are more than willing to give it to you. Works for awhile, but after a rain or too you'll need to reapply. I have done this for several years with good success. Do this until your larger plants get established and it will give those peas and beans a chance.
