You might need to sprinkle seeds and newly germinated seedlings twice a day. To keep the soil moist and protect young plants from the sun, temporarily shade them. Boards and umbrellas make good shade structures. When thinning, leave extra space between plants that will stay in the garden over the winter. Closely spaced plants are more susceptible to rots and slug damage in cool, wet weather than are those with adequate ventilation.
Control slugs as soon as fall rains start.
By reducing the population in early fall before the breeding season, you'll have less trouble during the winter. Fall also is the time to protect your plants from the weather. They also protect plants from frost and, just as important, cold rain. Many cool-weather crops thrive in western Oregon's mild winters. By covering plants with a coldframe or cloche, you can protect them from cold rain and frost and enjoy fresh vegetables throughout the year.
