What can I plant in August in the Pacific Northwest?

In August, the Pacific Northwest is still experiencing warm weather, making it a great time to plant a variety of vegetables and herbs. Here are some options for what you can plant in your garden during this month:

1. Corn Salad: Also known as mache or lamb’s lettuce, corn salad is a cool-season green that thrives in the Pacific Northwest’s mild climate. Sow the seeds directly into well-prepared soil and keep them consistently moist. The leaves are tender and have a mild, nutty flavor, making them a great addition to salads.

2. Arugula: This peppery salad green is a fast grower and can be sown directly into the garden or in containers. Plant the seeds in well-draining soil and keep them watered regularly. Harvest the leaves when they are young and tender for the best flavor.

3. Cilantro: Cilantro is a popular herb in many cuisines and can be sown in August for a fall harvest. It prefers cooler temperatures, so make sure to plant it in a partially shaded spot to prevent it from bolting too quickly. Sow the seeds directly into the soil and keep them evenly moist.

4. Winter Lettuce: Take advantage of the cooler temperatures in late summer to sow winter lettuce varieties. These lettuces are more cold-tolerant and will provide you with fresh greens throughout the fall and even into winter if protected from frost. Plant the seeds in well-prepared soil and keep them consistently moist.

To maximize your garden space, consider interplanting these cool-season crops with your existing warm-season crops. For example, you can sow arugula or cilantro seeds in between the vines of your squash or other sprawling vegetables. This way, you can make the most of your garden space and enjoy a continuous harvest.

When it comes to fruit trees, early August is a good time to summer prune if needed. This process helps control the growth of overly vigorous trees and keeps them compact. Use sharp and clean pruning tools to remove any excessive growth, water sprouts, or damaged branches. Pruning can also improve air circulation within the tree canopy, reducing the risk of diseases.

August in the Pacific Northwest offers a great opportunity to sow cool-season crops such as corn salad, arugula, cilantro, and winter lettuce. Take advantage of the mild climate and make sure to provide adequate water and care for your plants. Happy gardening!
