When Can I Plant Tomatoes in Seattle?

Tomatoes are a popular crop to grow in Seattle, but planting them at the right time is key to a successful harvest. In this article, we'll explore the best time to plant tomatoes in Seattle and tips for getting the most out of your crop.

Weather Considerations

Seattle has a unique climate, with cool and damp weather prevailing for much of the year. This can make it challenging to grow warm-weather crops like tomatoes. When planting tomatoes, it's important to wait until the soil has warmed up enough for them to start growing. Ideally, you should plant your tomatoes when the soil temperature has reached at least 60 degrees Fahrenheit.

In Seattle, this typically occurs in late May or early June. You can use a soil thermometer to check the temperature of the soil before you plant. It's also important to ensure that there's no frost danger when planting tomatoes. In Seattle, the last frost date occurs around April 15, so wait until after this date to plant your tomatoes.

Choosing a Variety

When selecting a tomato variety to grow in Seattle, look for those that are well-suited to cooler climates. These varieties will have a shorter growing season and are more resistant to disease. Some popular varieties for Seattle include Early Girl, Champion, and Celebrity.

You should also choose a variety that's appropriate for the space you have available. If you're growing tomatoes in a container or a small garden, look for varieties that are determinate, meaning they grow to a certain height and then stop. Indeterminate varieties, on the other hand, will continue to grow and produce fruit until the end of the season. These are better suited for larger gardens or areas with a lot of vertical space.

Planting Tips

When planting tomatoes in Seattle, it's important to provide them with plenty of sunshine and adequate water. Ideally, your tomato plants should receive at least six hours of sunlight per day. If you're growing tomatoes in a shaded area, consider using a grow light to supplement natural light.

To ensure that your tomatoes are getting enough water, it's important to water them regularly. Tomatoes need about one inch of water per week. If you're growing tomatoes in a container or raised bed, ensure that the soil is well-draining to prevent waterlogged roots.

Conclusion

Now that you know when to plant tomatoes in Seattle and how to choose the right variety, you're ready to start growing your own crop. With the right care and attention, you can enjoy fresh and delicious tomatoes throughout the season. Happy planting!
