Q.Planting sweet corn
Something is digging up and eating corn kernels day or two after I have planted. I put a small fence around patch and do not see any paw prints or scratch marks. The seeds I planted were coated with a pink powdery stuff and whatever was eating them was smart enough to discard the outer pink part. What could be eating my corn right out of the ground and what can I do to discourage them?
I'm not sure of the zone you are gardening in, but it could be a few different critters.
Mice, Voles, Squirrels, Chipmunks to name the most common.
I have used chicken wire tunnels over freshly planted seeds with some success in my own garden.
You can cut strips of chicken wire and make a half circle cage over the freshly planted seeds. Use landscape anchors to pin the wire into the soil. It may help to deter the pest.
