I can't keep up to the constant watering, and I don't want to either.
I plant out my wintersown stuff asap in spring. Plunk and run mode takes over, wherever there's a spot in a bed. Seedlings get transplanted as soon as they're big enough for me to handle- like a set or two of true leaves. In the spring weather, the rain takes care of watering, and the cool weather lets them establish easily. Once the hot weather is here, they need constant watering, protection from hot sun. It's a pain. Long term survival of my seedlings is absolutely best if planted in April or early May.
