Q.How Can I Discourage Squirrels and Chipmunks From Destroying My Sunflowers?
While squirrels and chipmunks are cute to watch, they give me no end of difficulty with regard to sunflowers. They dig up the planted seed. They chomp down sprouts and young plants. They devour the immature seed heads. And, if the plant survives that, they wipe out the bloom seed head. I have used pepper, cayenne, hot chili powder, but to no avail. Other than barbed wire, how can I protect my sunflowers from seed to maturity?
