Plant your winter garden NOW! September, when many new gardeners start to think about winter veggies is too late.
Sow arugula, beans, beets, broccoli raab, carrots, lettuce,Asian greens, peas, rutabagas, scallions, spinach, Swiss chard, turnips, and winter radishes that you want to eat over the winter. Check out West Coast Seeds’ Winter Planting Guide to learn what to plant now for fall and winter harvesting.
Transplant winter broccoli, cabbage and cauliflower that were seeded earlier. Quick growing sweetheart cabbages, such as Caraflex, Greyhound and Early Jersey Wakefield can still be started from seed.
Pick herbs for fresh use and for drying. Harvesting will keep them growing longer.
Spread a mid-season layer of compost or manure.
Keep deadheading flowers to keep the blooms coming. Leave some annual seeds to self-sow.
Remove any diseased foliage now, so it doesn’t get lost in the fall leaves.
Cut back the foliage of early bloomers like Brunnera and hardy geraniums, to revitalize the plants.
Prune summer flowering shrubs as the flowers fade.
Trim and feed hanging baskets to prolong their beauty.
Increase watering of container plants.
Watch for powdery mildew on zinnias & squash. Spray with a mixture of 1 tsp. baking soda mixed with 1 litre of water and a little liquid soap at the first sign of mildew.
Give annuals & vegetables a boost with liquid seaweed fertilizer.
Take pictures of your garden at peak. Take pictures of container combinations you’d like to repeat.

Then sit back and enjoy all you’ve accomplished!
