I don't have the succession planting thing quite mastered yet, but what I planted last August/September fared well in the greenhouse over the winter. The lone cauliflower that thrived is now heading. I'm seeing cabbage moths flutter across the lawn, but no damage yet.
The lettuce and parsnips are doing great. I pulled one beet, but is was not very large or round--I juiced it with a pineapple (needed some spring cleaning myself). It is so nice to have a jump start while waiting for the new plantings.
