For this part of the country, I plant potatoes on or about Saint Patrick's day....around March 17th. It reminds me of why us sorry Irishmen came over here and how desperate they must of been. Anyway, that beetle is not a problem here and my Irish Cobblers love my TLC with just a hoe.
Then there is all the other optional early crops as mentioned by /pine...peas, lettuce, spinach, radish etc. Then, after the last frost, (sometime after May 1st) is when the corn, pepper plants, tomato plants, cantaloupe, watermelon, cuke, okra seeds go in.
Did I mention Swiss Chard, beets, carrots....herbs ....:licking:
Good Wishes for your garden,
Mike
