Our Service Area

Our Commitment to Sustainability

Landscaping operations are often known for their egregious overuse of gas-powered tools and chemical applications. At Plant People Northwest, we are interested in being a different kind of company: one that respects our common space and the health of our planet and bodies.

We use only electric power tools. We purchase organic and local products as often as possible. We use digital, paperless invoicing. And we design for food production, water conservation and wildlife habitat. 

What Organic Means to Us

Most garden problems do not require either chemical or organic sprays; they can often be resolved through careful attention to soil moisture & health, plant placement, and skilled pruning. In the rare case that a plant does require treatment, we’ll communicate with you closely to make sure we are bringing approved products into your garden. 

Products such as fertilizer, compost, and mulch labeled “organic” are manufactured to a range of different standards. We purchase the best available and, when possible, buy local.

Why Choose Plant People Northwest

Poor design, and unskilled maintenance, can cost you more money and stress than they save. Overplanted or improperly pruned plants and trees are higher-maintenance, less attractive, and more susceptible to disease. Often, the damage of unskilled pruning may be corrected over several years of careful work by a trained gardener; other times, malpruned plants and trees are better off being replaced. Plant People Northwest is a member of PlantAmnesty, our esteemed local source for pruning and gardening education, and our crew prunes according to their standards. When designing a garden, we space plants to reach their full potential without impinging on one another (or your doors, windows and pathways).

We treat your garden with respect and approach our tasks with care. Many landscapers default to chemical fertilizers, herbicides and pesticides rather than addressing the root cause of a wilting plant, an aphid-infested rose or a lilac that won’t bloom. Our focus on soil fertility and “right plant, right place” cultivates a garden that is healthy, beautiful, and lower maintenance in the long run.

Our focus on continuing education also sets us apart from other landscape companies. All of our managers are Certified Professional Horticulturists with WSNLA, and many have also taken classes with Plant Amnesty and City Fruit.

With a focus on thoughtful, sustainable design, safe ecological practices, and highly skilled maintenance, your outdoor sanctuary is in good hands.

Plant People Northwest is a licensed, bonded and insured specialty contractor (#PLANEPN832BK).
