Being semi retired,I put in a small garden this year spuds,watermelon, onions and carrots. All before Good Friday. Now to keep it weeded!
Lots of tomatoes grown here but I have a black thumb with tomatoes. My boy grows them by the basket fullHow long is your growing season in South Dakota? Can you grow tomatoes? The soil is still too cold in Oregon. I'm keeping my plants under windows in the house. If you plant them too soon they just sit there and don't grow until the soil warms up. Maybe in a couple of weeks.
Frost in the fall is a bigger problem than the springIt is a little early for watermelon, even here
