Long ago, I was told by a wise old Italian woman in New England that nothing should go in the ground until the first full moon after Mother's Day. We are in Zone 5, both in New Hampshire and Montana. New Hampshire is getting snow in May (nuts), but it's pretty nice here in Montana, and the last full moon was 3 days before Mother's Day so we are rolling the dice. Plants are going in. Stuff from seed include Sunflowers, Sage, Columbine and Zinnia. Purchased plants include Wave Petunias and Dahlias. I'll keep posting pictures as the season progresses. Get out there and dig in the dirt, it is good for the soul!
