When to Plant Strawberries in Seattle: A Guide for Emerald City Gardeners

Seattle’s mild climate offers a decent growing season for strawberries. Generally, the best times to plant strawberries in Seattle are in the spring (April-May) or in the fall (late August-September) to give them a head start before the weather extremes of summer and winter.

Spring Planting: April-May

Planting strawberries in the spring allows the plants to establish themselves during the warmer months. The soil begins to warm up, giving the roots a better chance to develop before the heat of summer arrives. When planting in spring, consider the type of strawberry plant you’re using:

• June-bearing strawberries: These produce one large crop in June. Spring planting is ideal for these to yield fruit the following year.
• Everbearing strawberries: These produce several smaller crops throughout the season. Spring planting will likely yield a smaller crop in the first year and a larger crop in subsequent years.
• Day-neutral strawberries: These produce fruit throughout the growing season, regardless of day length. Spring planting allows for a continuous harvest during the first season.

When planting in the spring, ensure the threat of frost has passed. You can check local weather forecasts to be sure.

Fall Planting: Late August-September

Fall planting offers strawberries the opportunity to develop a strong root system before winter sets in. This can lead to a more abundant harvest the following spring and summer. It is critical to give the strawberry plants enough time to grow before winter.

Consider using a layer of mulch to protect the plants from freezing temperatures and help retain moisture in the soil. Straw is a popular and effective choice, as noted in this Wikipedia article on strawberry cultivation.

Choosing the Right Variety for Seattle

Selecting the right strawberry variety is key to successful growing in Seattle. Look for varieties that are well-suited to the Pacific Northwest climate. Some popular choices include:

• Hood
• Puget Reliance
• Rainier

These varieties are known for their disease resistance and ability to thrive in the local conditions.

Soil Preparation is Crucial

Whether you are planting in the spring or fall, adequate soil preparation is essential. Strawberries prefer well-drained soil that is rich in organic matter. Before planting, amend the soil with compost or other organic materials to improve drainage and fertility. Slightly acidic soil (pH 5.5-6.5) is ideal for strawberry plants.

Frequently Asked Questions

When is too late to plant strawberries in Seattle?

Planting strawberries much later than May in the spring may not give them enough time to establish before the heat of summer. Planting after September in the fall may not give the plants enough time to develop before winter.

Can I grow strawberries in containers in Seattle?

Yes, strawberries grow well in containers. Make sure the container has drainage holes and use a good quality potting mix. Everbearing and day-neutral varieties are particularly well-suited to container gardening.

How much sun do strawberries need in Seattle?

How often should I water my strawberry plants?

Water your strawberry plants regularly, especially during dry periods. Aim to keep the soil consistently moist, but not waterlogged. Mulching around the plants can help retain moisture and reduce the need for frequent watering.
