Rabbit ate green beans, some stalks, will they grow back?

Nope - sorry, each bean puts up 1 shoot - once it is eaten, it doesn't grow back. Good news, though, it is still early enough that you can replant the beans, they are quick to grow. I like the green French string bean variety, they're long & thin, grow quickly and produce more beans per plant than most varieties.

If there are just stalks but no little nubs of new branches or some tiny bean pods, it's unlikely they will grow back and bear fruit. Wascally wabbits! 😇

When you replant, take a length of hardware cloth or chicken wire and bend it over your row like a tunnel. Be sure to close off the ends by crimping the ends or running wire across the opening. If the culprits were birds, they will leave the plants alone after the plant gets a bit taller with more leaves, so you can eventually remove the tunnel before the plants start to poke through the wire. If rabbits are the problem and continue to eat the bean plants after they get taller, I would suggest low pvc hoops with bird netting over the top. Lots of sites show how to put up such hoops. Look for instructions for season extending row covers, but use bird netting instead. This only works with bush beans (not pole) and short varieties of sugar snap peas like Sugar Ann.

Replant new seeds in there place. I had some eaten off earlier and did that. I also put down cayenne pepper and shaved Irish Spring soap around my beans and corn and haven't had the problem again.

Cayenne pepper is a natural solution that a LOT of Hometalkers swear by. Make sure to reapply after rain!
