Planting in Spring for a Summer Harvest

Garden Essentials: location, soil, seed varieties and good cultural practices.

Select a good location

Your site will need at least 6 hours of sunshine. Pay attention to where shadows fall from surrounding trees or buildings in each season. As leaves fill in the spring they may cast shadows on your garden. Gardening in containers adds the advantage of a moveable garden.

Sunlight Requirements of Some Vegetables

Partial Sun, 4-6 hours Beets, Carrots, Swiss Chard, Lettuce, Onion, Parsley, Peas, Radishes, Spinach

Full Sun, 6 hours + Broccoli, Cabbage, Cauliflower, Collards, Garlic, Kale, Kolrabi, Mustard Greens, Beans, Squash

Building Good Garden Soil: As simple as 1, 2, 3.

1. Add organic matter. At least 1-2 inches every year.
2. Add organic soil amendments. Organic fertilizers release slowly and provide other important nutrients. Most soils in the Seattle area are acid but most vegetables like a neutral soil. Adding dolomite lime sweetens the soil and contains two other important minerals, calcium and magnesium.
3. Make raised beds. “Fluffing up” the soil into raised beds improves drainage and encourages good root growth.

Vegetable Seed Varieties

When planning, be sure to choose varieties that grow well in the Northwest and are specific for a fall harvest. For container gardens select dwarf or bush varieties. The Maritime Northwest Garden Guide and Territorial Seed Catalog are good resources for varieties successfully grown in the fall and west of the cascades.

Good Cultural Practices--Secrets to Success
Plant Spacing

Vegetables grown on raised beds can be planted close together shading out weeds and self mulching as they grow. Trellising plants that vine helps to use garden space to the maximum.

Many vegetable plants can be grown in containers. Smaller vegetable plants can thrive in containers 6 inches deep like lettuces, spinach, other greens and herbs but larger plants like bush type squashes need at least a 5 gallon container.

Watering

Seeds that are directly sown into the garden will require even moisture. A fine layer of compost or floating row cover can help keep the soil moist by decreasing evaporation. Once your seedlings are up and growing water regularly:

• Water deeply as plants are being established to encourage deep root growth.
• The easiest way to determine if watering is needed is dig down 4-6 inches into the bed. If soil is dry at that depth, your plants need water.
