I have little reminders on when I plant my garden here are a few.....
I plant my tomatoes, melons and eggplant when the peonies flower and when the black locust bloom.
I plant my pole beans and cucumbers when the apple blossoms drop.
I plant my potatoes when the white oak leaves are as big as a cats ear.
I plant my spinach, beets and onions when the daffodils bloom.
I plant my broccoli and cabbage after the dog-woods have dropped their flowers.
