Hi there! I'm writing about drought-resistant landscaping and would appreciate your professional input. I am looking for a landscape professional or horticulturist to answer the following questions: 1. What are some common mistakes homeowners make when transitioning from a traditional turf lawn to a xeriscape design? 2. When planting succulents in an outdoor rock garden, what specific soil preparation is critical to prevent root rot during unexpected heavy rains? 3. Rain gardens are meant to capture runoff, but how can a homeowner test or amend their soil to ensure the water drains fast enough to prevent mosquito breeding? 4. Ornamental grasses are excellent low-water options. How and when should they be cut back to maintain plant health and reduce fire hazards in dry climates? 5. If a homeowner insists on keeping a small patch of traditional turf, what is your top technique for training those grass roots to grow deeper and become more drought-resistant?
