Securing ladder in ground for trellis
I am going to try to use 2 old rickety wooden ladders as trellises for my cucumbers and squash this year. When open, the ladders are about 6' and 8' tall. Our area has occasional bouts of really strong winds, but not steady wind all the time. I want to protect the ladders from falling over, but I don't want to permanently install them (so cementing in the ground is not an option.) I know their are easier ways to make a trellis, but I want to use the ladders, since they are free and not good for anything else. Any suggestions? Thanks!
