I generally have a nice plot of sunflowers in my garden...we compete (a losing battle :)) with the birds for the seeds...I always plant more than what we need of the popular plants, like sunflowers and corn...raccoons have to eat also you know...
Yes, in all my gardens I think the same thing, at least 1/3 of the planting go to wildlife; the rest to us.
The only way to keep critters out would be large greenhouses — and that’s not an option.
