When to plant blueberries in Bellingham, WA

Plant blueberry bushes in Bellingham Mar 15 – May 3.

Easy Plant potted or bare-root bushes

Why these dates

Bellingham's typical last spring frost is March 31. As a hardy perennial, this crop doesn't need to wait for that date. In the west-side valleys, though, the soil usually isn't ready to work until about March 15.

West-side valleys. The Willamette Valley, Puget Sound and southern Oregon valleys. Long frost-free seasons, but soil stays cold and wet into May, so warm crops wait for warm soil, not just the last frost.

Step by step

  1. Pick a sunny spot with soil that drains well, and mix in an inch or two of compost.
  2. Plant blueberry bushes Mar 15 – May 3, 4 to 5 feet apart. Same depth as in the pot.
  3. Mix peat moss or acidic compost into the planting hole, mulch with sawdust or bark, and pinch off flowers the first year.
  4. Harvest: Pick berries a few days after they turn fully blue, when they roll off into your hand.

Varieties that do well here

  • Duke (early)
  • Chandler (huge berries)
  • Bluecrop

Watch out for

Birds. Cover bushes with netting as berries color, or plant extra.

Need acidic soil (pH 4.5 to 5.5), which much of western Oregon and Washington already has. Plant two varieties for better crops. West of the Cascades, fall planting works well too.
