In northern regions, early and late seasonally cool weather gives the gardener an opportunity to plan and execute two cool vegetable crop cycles within the same growing year: one geared toward very early spring, the second timed to end with a late fall/early winter harvest. Most of the cool season crops go to seed or become bitter and/or inedible when hit with summer heat, making planting times crucial. With careful planning, grabbing a bit of extra crop time from Momma Nature is doable.
