For a few weeks each March, after the winter rains have done their work, the slopes of Cowles Mountain turn a startling green, and the trail up from San Carlos fills with early hikers chasing sunrise from the highest point in the city. Below them, neighborhood gardens wake up too: new growth everywhere, weeds racing the flowers, lawns perking up after the cool months. Eco Gardeners does the hands-in-the-soil work that keeps a San Diego yard in step with that sudden surge. The job is gardening and lawn care, which means tidying beds, pulling what doesn't belong, and keeping grass trimmed and the garden in shape before the dry season arrives. There is something hopeful about a garden tended in March, when the hills of Mission Trails are at their greenest and every plant seems to believe the rain will last forever.
