MASTER GARDENERS: The power of blueberries for Washington and you

By Marie Kurka-Brown

Blueberries may be Washington’s quiet powerhouse — leading the nation in production, expanding into global markets, and thriving in backyard gardens across the state. As we step into February, it’s the perfect time to plan propagation strategies that support both personal harvests and community education.

Whether you’re working with hardwood cuttings, layering techniques, or container starts, propagating blueberries offers a hands‑on way to connect science‑based gardening with seasonal stewardship. In this article, we’ll explore propagation methods, timing, and tips for success — all rooted in the joy of growing something that nourishes both soil and story. And maybe a little history along the way.

Soil Testing and Water Wisdom

Blueberries are famously picky about their soil — but once you meet their needs, they reward you with vigorous growth and abundant fruit. They can be grown in your garden, in raised beds, pots, and even in that old wheelbarrow you’re not sure what to do with.

Blueberries rely on acidic conditions to absorb nutrients like iron, magnesium, and manganese. The ideal pH range is 4.5 to 5.5. If you’re not sure about your soil, have it tested. A soil test helps determine pH and nutrient levels, and you can have it done through a university or County Extension office. Requirements vary, so it’s best to call ahead.

Blueberries thrive in the Pacific Northwest’s moist climate, but they still need well‑draining soil and consistent watering. During fruiting season, water deeply — up to 4 inches per week — and mulch to retain moisture. Raised beds and mounded soil help balance hydration with healthy root aeration.

Closing Reflection: One Cutting at a Time

For me, growing blueberries is more than a seasonal task — it’s a personal journey. As a cancer survivor, I’ve come to cherish the rhythm of gardening: the movement, the meditation, the quiet joy of tending something that gives back.

With fourteen bushes thriving in my garden, I freeze, share, and savor blueberries all year long. They nourish my body, yes — but they also nourish my spirit. I also steward a nonprofit garden, where friends facing food insecurity are invited to pick what they need, blueberries included.

Whether you’re planting in the ground, a pot, or an old wheelbarrow, propagation is a way to root yourself in possibility. It’s a small act with big impact — supporting food security, community education, and personal stewardship, one cutting at a time.
