Isn't it great? My 4'x4' extra-high raised bed has been the best producer so far. It's 4 cedar 2x4's stacked up but the soil is only at the top of the bottom two. On the North West and North East sides, I wrapped a folded over heavy plastic sheeting covering the wood AND the border fence, and all along the South East side border fence, stood up plastic egg cartons (the 3-fold kind) held in place with a bit of string. I then covered the top with a floating cover, initially doubled, tightly held down by wrapping a couple of tomato stakes on either end. Since this bed is on a slight slope (5Ã‚Âº or so) facing South West it's "almost" a cold frame. Vegs in there are twice as big as the vegs planted in the open. I've been harvesting lettuce out of there and radishes should be ready soon (I've been eating the cullings). Now that the vegs are getting bigger, I also rooted out the chickweed and had that in my salad the other day.
I tried sowing Provider (early cold hardy bush bean) on April 2, protected under a floating cover. They were just starting to lift their shoots after a couple of days of 70Ã‚Âº sunny days, but now the temps down to 50's so they'll be slow going until this weekend when it's supposed to get warm again. My Nintoku Giant (broadbean and I thought was supposed to be planted with cold-weather crops so was sowed on March 22) is also juuust starting to come up.
Early planting can be rewarding, but it also takes a lot of patience!
2cents -- I dithered and folded and didn't plant asparagus -- definitely on the list for next year!
