When to Plant Tomatoes in Seattle 2022

Seattle, Washington is known for its mild summers and long rainy season, making it an ideal place to grow tomatoes. However, knowing when to plant tomatoes in Seattle in 2022 can be a challenge, as the weather can be unpredictable. In this article, we will discuss the best time to plant tomatoes in Seattle in 2022 and provide tips for a successful tomato harvest.

Factors to Consider

Before planting tomatoes in Seattle, it's important to consider several factors to ensure a successful crop. The first factor to consider is the average last frost date. In Seattle, the average last frost date is around March 27. It's recommended to wait until after this date to plant tomatoes.

Another factor to consider is the soil temperature. Tomato plants prefer warm soil with a temperature between 60-70 degrees Fahrenheit. If the soil is too cold, the seeds will not germinate properly. Using a soil thermometer can help you determine whether the soil is warm enough for planting.

Lastly, consider the variety of tomato you are planting. Some varieties of tomatoes are more cold-tolerant than others and can be planted earlier in the season. Determinate varieties, which grow to a specific size and produce fruit all at once, are also recommended for Seattle's cool summers.

Best Time to Plant Tomatoes in Seattle

The best time to plant tomatoes in Seattle is between late April and early June. This allows enough time for the soil to warm up and for the seedlings to establish themselves before the cool Seattle summer sets in. Planting too early can result in stunted growth and a lower yield.

If you are planting tomatoes from seed, it's recommended to start them indoors 6-8 weeks before the last frost date. This allows enough time for the seeds to germinate and the seedlings to grow before transplanting them into your garden. Transplanting should be done on a cloudy day or in the late afternoon to minimize stress on the plants.

Tips for a Successful Tomato Harvest

To ensure a successful tomato harvest in Seattle, it's important to provide the plants with the right growing conditions. Here are some tips:

- Choose a sunny location with well-draining soil. Tomatoes need at least 6 hours of direct sunlight per day.

- Water deeply and regularly to keep the soil consistently moist. Avoid getting water on the leaves to prevent fungal diseases.

- Use a trellis or stake to support the plants as they grow. This will help prevent the fruit from touching the ground and reduce the risk of rot or disease.

- Fertilize regularly with a balanced fertilizer to provide the plants with the nutrients they need to grow and produce fruit.
