What Month to Plant Tomatoes from Seed in Seattle

Seattle, Washington, is known for its mild, rainy climate that is perfect for growing a variety of fruits and vegetables. If you're looking to grow tomatoes from seed in Seattle, you need to know the right time to plant so you can get the best yield. Tomatoes are heat-loving plants and require warm soil to germinate and grow properly, so it's important to plant them at the right time to avoid stunted growth, disease, or poor fruit production.

Choosing the Right Tomato Variety

Before you start planting tomatoes from seed, it's important to choose the right variety that is suitable for Seattle's climate. You should select a tomato variety that is heat tolerant and can withstand the cool and damp climate of the Pacific Northwest region. Some of the most popular tomato varieties for Seattle include Early Girl, Oregon Spring, and Fourth of July. These varieties are early maturing and can produce fruits earlier than other varieties, thus ensuring a higher yield. You can also consider other heirloom varieties like Cherokee Purple, Brandywine, and San Marzano, which are also suitable for Seattle's climate.

When to Plant Tomatoes from Seed in Seattle

The best time to plant tomatoes from seed in Seattle is in late March or early April. At this time, the soil is starting to warm up, and the danger of frost is significantly reduced. Germination takes 7-10 days, and after about four weeks, your seedling will be ready to be transplanted into the garden. It's important to note that if you plant seeds too early, the plants may be stunted by the cold temperature, and if you plant too late, the fruits may not ripen before the first frost in autumn.

Preparing the Soil for Planting

Now that you know when to plant tomatoes from seed in Seattle, it's time to prepare the soil. Tomato plants prefer well-drained soil with a pH range between 6.0-7.0. The soil should be fertile, and if your soil is poor, you may need to amend it with organic matter such as compost, manure, or fish emulsion. It's also essential to ensure your garden bed is in a sunny location with at least six hours of direct sunlight.

Planting and Caring for Tomatoes

When planting tomatoes from seed in Seattle, you should sow the seeds about a quarter of an inch deep and about 3-4 inches apart. After the seedlings have grown to a height of around four inches, you can transplant them to the garden. Make sure to space the plants about two feet apart to allow enough room for growth. It's also essential to fertilize the plants regularly with a balanced fertilizer and water them to keep the soil evenly moist throughout the growing season. Mulching around the plants can help retain moisture and prevent weeds. If you notice any signs of disease or pest infestation, act quickly to prevent the problem from spreading.

Conclusion

In conclusion, growing tomatoes from seed in Seattle can be a rewarding experience if you know the right time to plant and take proper care of your plants. By choosing the right variety, preparing the soil, and planting at the optimal time, you can ensure a bountiful harvest come summer. Happy gardening!
