As the summer crops fade, I am increasing the numbers of seedling I'm planting. Mostly greens: lettuce of all types, arugula, spinach, endive and escarole and beets. They'll go into my community plot after the squashes and corn are pulled (only 26 days until frost!! OMG). And then, they'll go into my cold frame when the cucumbers finish. I had such a nice early spring cold frame full of greens that I'm looking forward to fall. I think they will grow well past the first frost.
I've resorted to starting all my seeds inside under lights. The sun and rain are too unpredictable for small seedlings outside in the big world, especially when my schedule is all mixed up.
