The cicadas will love your young vegetation, so you may want to
protect with an insect cover or wait to plant the lettuce until
august.

As I understand it, periodic cicadas feed almost exclusively on young tree
branches and twigs. I don't think your lettuce is as risk from them,
although slugs and earwigs may end up being your nemesis.


sorry to double.
