Home gardening resources and plant sales

Gardening in the Puget Sound region gets the advantage of rich volcanic soils, abundant rain, and year-round temperate weather.

However, Northwest gardeners also face several challenges: a shortage of sunny days, a growing season that starts later than other parts of the country, and understanding the microclimate where your garden grows.

Other specific challenges to your site might include clay soils, acidic soil, dry conditions, shade, slugs, and other impediments to growing beautiful trees, shrubs, flowers, and vegetables.

Fortunately, there is an avid gardening community in the Seattle-Tacoma area. Listed below, you’ll find gardening resources and information for the Puget Sound region, including ideas and inspiration from experts, social gardening clubs, and resources for vegetable gardening.

Following these lists, you’ll also find a calendar of upcoming plant sales throughout the Puget Sound region.

Information about rain gardens

A rain garden is a beautiful and very functional planting area in the landscape specially designed and constructed to filter rainwater before it reaches the sewer system. Besides protecting our water supply, a rain garden takes less water to maintain than lawns or other types of garden plantings without taking conservation into account.

Vegetable Gardening Resources

The following resources for gardening in the Pacific Northwest focus on growing food: fruits, vegetables, herbs, and other edibles. These free resources provide plenty of guidance for starting a vegetable garden, especially if you live in an urban area in Washington State.

A vegetable garden in the city presents some challenges. There is limited green space for growing food. Homeowners can be overwhelmed by a garden project. Condo and apartment dwellers are faced with container gardening or shared garden spaces (known as “p-patches” in Seattle–more about this later) as their only prospect for a garden.

Besides urban challenges, Mother Nature can bring on too much rain (or not enough), wind, or freezing temperatures at inopportune times–just when you’re ready to plant in spring or late in summer as the tomatoes are nearly ripe. There is also the problem of overabundance, too much zucchini or lettuce than you can eat before it spoils.

Starting and maintaining a vegetable garden takes planning, flexibility, imagination and resourcefulness to be successful. However, the rewards are abundant. We’ve pulled together the following resources to get you started.

Home vegetable gardening is one of the most rewarding DIY (do-it-yourself) projects anyone can do, whether you own or rent a house, or live in a condominium or apartment. Growing some of your own food is great for the earth, does wonders for your belly, and can feed your soul.

Planting seasons for vegetables in Puget Sound gardens

There are two planting seasons in the Northwest: spring (for harvest summer through fall) and late summer (for harvest in fall or spring). How early or late in each of these seasons you can plant depends on the crops you are planting. Planting times also differ for seeds versus “starts” (plants started in small pots for transplanting into the vegetable garden).

In spring, planting dates stretch from February to June. Spring-planted crops will be harvested through summer and into early fall.

The average first planting date is mid-March, around St. Patrick’s Day (March 17).
Hardy crops, such as peas can be planted earlier, in mid-February.
Tender crops, such as basil and tomatoes should be planted mid-May to mid-June.

In summer, plant new crops to be harvested in fall, winter or spring:

In early August, plant these crops for fall harvest: cilantro, broccoli rabe, green onions, radishes, and greens such as kale, spinach, and chard.
In late August, plant these crops to over-winter and harvest in early spring: beets, broccoli, cabbage, carrots, garlic, and turnips.

For more details on what to plant and when, refer to the above resources or visit your local library.
