I just thought where to plant the walking onions. Remember, I have two wood planters on the ground in the garden and the squirrels and/or birds ate the lettuce seed out of both of them. I could put a few walking onions in the middle of the longest planter and they could just fill it up. If they tried to walk over the edge of the planter onto the ground I would yell at them to get back in their “house”. Or, I could cut them if they walked over the edge.
I really want the other planter to grow lettuce next spring and I’ll put net over both the young onion plants and lettuce seed to keep them from being murdered again.
I use floating row covers over the lettuce instead of netting. No bugs or birds ever bother them.
