PLANT The autumnal equinox marks summer’s end, but Portland usually gets bonus weeks of warmth in September and even October—a boon for tomatoes, peppers, eggplant, squash, cucumbers, and beans. Fertilize weekly with fast-acting liquid fish and kelp to keep production up right through season’s end. As summer wanes, begin fortifying your soil for next year by planting cover crops in your vegetable garden or, for that matter, any fallow ground. Starting in late August, sow red clover, annual winter rye, and Austrian winter peas to build soil nutrients and minimize erosion. You’ll chop them up and turn them over in late spring. September and October are ideal for dividing and replanting crowded spring-flowering perennials like peonies and iris. Dig out whole clumps with a garden fork or shovel, and then divide into at least three hefty pieces.
