When we moved in I started a garden in an empty corner of our backyard to attract birds and butterflies. As usual it attracted bunnies, which bit the heads off of all the flowers as soon as they began to open! Last summer we set up a temporary fence around the garden to keep the bunnies out and give the plants a chance to get established. This summer the flowers were finally able to bloom! I'm hoping the plants are strong enough now to survive on their own so I can remove the fence next spring.
