Planting tulip bulbs in northwest Washington

Updated November 3, 2026

Spring tulips start in the fall. Tulip bulbs need a stretch of winter cold to bloom, so they go into the ground months before you see anything. Our wet winters and mild summers bring a few local quirks, but tulips grow well here. The Skagit Valley is proof.

When to plant

In northwest Washington, plant tulip bulbs in October and November, once the soil has cooled. If you miss that window, get them in as soon as you can, even in December, as long as the ground isn't frozen. Bulbs left in the bag until spring won't do much.

How to plant

Pick a sunny, well-drained spot. Tulips want full sun or at least part sun. The bigger risk in our climate is water. Bulbs sitting in soggy winter soil rot, so avoid low spots where puddles form. In heavy clay, work in compost or coarse sand, or plant in raised beds or containers.

Go deep. Washington State University Extension recommends planting 6 to 8 inches deep, measured from the base of the bulb, and about 4 inches apart. Shallow planting is one of the most common reasons tulips don't come back. Set each bulb with the pointed end up.

Water once, then leave them. Water well at planting to settle the soil, then let winter rain do the rest. Overwatering invites fungus. Bulb fertilizer mixed into the planting hole is optional.

Keeping squirrels and deer away

Squirrels, voles, chipmunks, rabbits, and deer all like tulips. Planting deep helps, and WSU Extension also suggests peeling off the loose papery skins before planting. For burrowers, line or cover the planting area with hardware cloth, gravel, or crushed oyster shell. For rabbits and deer, use mesh, fencing, or a repellent on the new leaves in early spring.

Will they come back next year?

Tulips are perennials, but many hybrids fade after a year or two here, because they evolved for cold winters and hot, dry summers. Many gardeners treat them as annuals and plant fresh bulbs each fall. If you want tulips that return, choose species or botanical tulips, Darwin hybrids, Fosteriana (Emperor) types, or some Triumph tulips.

After they bloom, snap off the spent flowers but leave the leaves until they yellow and die back on their own. The leaves feed the bulb for next year, so cutting them early weakens it.

Where to buy

Local growers sell bulbs in late summer and fall, and some take orders during the April tulip festival for fall pickup or shipping. Buying locally means fresh, firm bulbs of varieties that grow well here. Avoid bulbs that are soft, moldy, or very lightweight.
