When to Plant Chives in Washington (2026 Guide)
Growing chives in Washington is an excellent choice for both novice and experienced gardeners. Their low-maintenance nature and ability to thrive in various conditions make them a perennial favorite. In regions like Bellevue, where the median last spring frost is April 9, timing your planting is crucial for ensuring a robust harvest throughout the growing season.
Chives are not just flavorful; they are also a striking addition to any garden. With edible lavender flowers blooming in late spring, they provide both visual appeal and culinary delight. If you're in Vancouver, keep in mind the typical last frost date of April 20 to ensure your chives have the best start. It's a practice that pays off, as chives can return year after year with little effort.
Understanding the annual frost cycle in Washington is key to maximizing your harvest. In colder areas like Olympia, where the last frost date can extend to May 6, careful planning is necessary. By choosing the right time to plant and cultivate chives, you can enjoy their mild onion flavor from early spring through late fall, enhancing various dishes and your gardening success.

Common Mistakes Growing Chives in Washington
- One common mistake is planting chives too late. In Washington, the last frost can vary significantly; overlooking dates like May 6 in Olympia may lead to poor establishment for the season.
- Many gardeners forget that chives thrive on regular cutting, much like their fellow herbs. Chopping them back encourages fresh growth, so failure to do so can result in limp, unproductive plants throughout Washington's summer.
- Overwatering is another frequent error in Washington gardens. The coastal humidity might lead you to think they need constant moisture, but this can cause root rot. Chives prefer a well-drained medium, especially during the rainy months.
- Ignoring the spacing needs of chives often leads to overcrowding in the garden. Washington conditions can benefit from spacing them at least 8-12 inches apart to allow for healthy growth and prevent aphid infestations.
- Some novice gardeners assume chives are only a spring herb. In reality, their flavor builds throughout the growing season, with peak harvest times in June and July. Don't overlook late summer harvesting opportunities in Washington.
