diana nicole

diana nicole, it takes a garden

Helping homeowners grow a self-sustaining landscape with the native plants of our natural plant communities adapted to the landscape for ease of maintenance, maximum ecosystem benefit, and wildlife support. By using swales and a mix of native plants of varying root systems and leaf structure, my gardens amend the soil, store atmospheric carbon, clean water, increase rainfall penetration, and support nature while reducing or eliminating most irrigation.
