Container Vegetables in the Pacific North West... - Knowledgebase Question

Question by Keippala

I am new to the Seattle Area (SE of Seattle) & would like a container vegetable garden for my family in elevated wooden containers, 20? x 48?, 18 inches? deep. I have drilled holes in the bottom & am planning on lining it with a weed barrier fabric to help with drainage without losing soil. What mixture of soil, perlite, & sand do I use? What vegetable plants are good for the area? Any other suggestions?

If you mix your own soil, use a 1/3 ratio of amendments to garden soil. I use a wheelbarrow to roughly measure everything. Start with three wheelbarrows of garden soil, dump it into the bed, then make a mix of one part compost, one part sand, one part perlite or vermiculite together in the wheelbarrow and dump it into the bed. Mix it together with the garden soil and repeat the process until the bed is filled. Since Seattle summers are short and cool, choose short season varieties of tomatoes, peppers, winter squash and melons. Other good choices are potatoes, carrots, lettuce, beans, peas, radishes, summer squash, and cabbage. Enjoy your garden!
