When to Plant Tomatoes in Seattle

Tomatoes are a delicious and versatile fruit that can be grown in many different climates. While Seattle's rainy weather may make some people hesitate to plant tomatoes, with the right preparation and timing, you can successfully grow these juicy treats in the Emerald City. In this article, we'll explore the best time to plant tomatoes in Seattle and provide some tips on how to ensure a bountiful harvest.

The Best Time to Plant Tomatoes in Seattle

The best time to plant tomatoes in Seattle is from late May to early June. Seattle's climate is known for its cool and damp weather, which can make it challenging to grow tomatoes. However, tomatoes thrive in warm temperatures, so it's essential to wait until the weather warms up before planting them. Once the soil temperature reaches 60-65°F, you can begin planting your tomato seeds.

Preparing Your Soil for Tomato Planting

Seattle's soil tends to be acidic and low in nutrients, which can make it difficult for tomatoes to grow. To prepare your soil for planting, first, test its pH level. If the pH level is below 6.0, you'll need to add lime to the soil to raise the pH level. Additionally, adding organic compost or fertilizer will help provide the necessary nutrients for healthy plant growth. Mix the lime, compost, and fertilizer into the soil before planting your tomato seeds.

Choosing the Right Type of Tomatoes to Plant

Not all tomato varieties are created equal when it comes to growing in Seattle's climate. Here are some excellent tomato varieties that will flourish in Seattle:

Early Girl - a vine-type tomato that produces lots of fruit in a short amount of time

Siletz - a determinate tomato that is resistant to disease and produces medium-sized fruits

Sun Gold - a cherry tomato variety that is sweet and flavorful

Beefsteak - a large, juicy tomato that is perfect for slicing and sandwiches

Planting and Caring for Your Tomatoes

When planting your tomato seedlings, be sure to space them at least 2-3 feet apart to ensure they have room to grow. Tomatoes need plenty of sunlight, so plant them in a spot that receives at least six hours of direct sunlight per day. Regularly water your tomatoes; they need around 1-2 inches of water per week. Additionally, you may want to add a layer of mulch around the base of your tomato plants to help retain moisture in the soil.

Harvest Time

Tomatoes typically take around 70-80 days to mature fully. You'll know when your tomatoes are ready to be picked when they turn bright red and are firm to the touch. Harvest your tomatoes as they ripen, as leaving ripe tomatoes on the vine can cause them to split or rot. Enjoy your freshly picked tomatoes in salads, sandwiches, or as a tasty snack!

In Conclusion

By following these tips, you can successfully grow tomatoes in Seattle's unique climate. Remember to wait until late May or early June to plant your tomatoes, prepare your soil by adding lime and fertilizer, choose the right varieties, provide plenty of sunlight and water, and harvest your tomatoes as they ripen. Happy gardening!
