plant corn when oak leaves are as big as squirrels ears
This season is going so fast I can't keep up with it! Already the oak leaves are opening. I am planting more by my calendar than phenology, just because I can't seem to keep up this year. The dandelions have been open a week and I still haven't finished planting my potatoes and I haven't started planting my carrots. I will keep trying to catch up.
Here's some other phenology advice:
When red winged blackbird females return its time to plant peas.
When the chickadees build their nests, plant peas and spinach.
When dandelions are blooming plant potatoes, beets, lettuce, spinach and carrots.
When the iris bloom, plant the peppers and eggplants outside.
Plant beets, lettuce, spinach when lilac is in first leaf.
When lilac blooms, plant beans, cukes and squash.
Plant corn when oak leaves are the size of squirrels' ears.
Plant your corn when apple blossoms start to fall.
