Introduction

Tomatoes are a popular vegetable among garden enthusiasts in Western Washington. Growing tomatoes can be a rewarding experience, but it requires proper timing and planning. In this article, we will discuss when to plant tomatoes outside in Western Washington to help you make the most out of your garden this year.

Climate in Western Washington

To determine the proper planting time for tomatoes, it's important to understand the climate in Western Washington. The region experiences a maritime climate with mild temperatures and plenty of moisture. The average temperature during the summer months is around 70°F, making it an ideal climate for growing tomatoes. However, the region also experiences cool, wet springs that can delay the planting season.

When to Start Seeds

If you are starting your tomato plants from seeds, it's recommended to start them indoors about 6-8 weeks before the last frost. The last frost in Western Washington typically occurs around the end of March or early April, so starting your seeds indoors around mid-February is ideal. This will give your tomato plants enough time to mature and establish themselves properly before transplanting them outside.

When to Transplant Outside

After starting your tomato seeds, it's important to wait until the soil temperature has warmed up before transplanting them outside. The ideal soil temperature for planting tomatoes is around 60-65°F. This usually occurs around mid-May in Western Washington. It's important to wait until the soil temperature has warmed up because planting in cooler soil can stunt the growth of your tomato plants or cause them to die.

Tips for Transplanting Tomatoes

When transplanting your tomato plants outside, it's important to keep in mind a few tips to ensure their success. Make sure to choose a sunny spot with well-draining soil. Tomatoes need at least 6-8 hours of sunlight a day to thrive. Moreover, they prefer slightly acidic soil with a pH of around 6.0-6.8. Be sure to plant your tomato seedlings deep in the soil, leaving only a few leaves above the surface. This will help the plant establish a strong root system.

Conclusion

Growing tomatoes in Western Washington can be a fun and rewarding experience. By understanding the climate in the region and proper planting timelines, you can ensure a bountiful harvest. Remember to start your seeds indoors around mid-February and wait until the soil temperature has warmed up before transplanting outside. With proper care and attention, you can enjoy delicious, homegrown tomatoes all summer long.
