My mission is to translate peer-reviewed soil science into practical guidance every gardener can apply. Too many homeowners work against their soil — understanding it is the single biggest unlock for a thriving yard.

About

With 22 years of experience in horticultural research, Dr. Vance specializes in soil health, native plant ecology, and climate-adaptive gardening. Her soil pH research at Cornell University fundamentally changed how extension programs teach home gardeners to manage soil chemistry, and her field studies on mycorrhizal networks in Pacific Northwest forests are cited in university curricula across the country.

Editorial Impact

Dr. Vance has reviewed and verified 186 plant profiles in our database, with particular focus on hardiness zone accuracy, soil amendment recommendations, and water-use efficiency for Pacific Northwest species.

Her research background in native plant ecosystems directly informs our editorial approach to sustainable landscaping, helping homeowners reduce water consumption while supporting local wildlife habitats and beneficial insect populations.

As a longtime contributor to Oregon State University extension programs, Dr. Vance applies peer-reviewed methodologies to every profile she reviews — ensuring our composting and soil management guides reflect current scientific consensus rather than gardening folklore.
