What is the colored, fuzzy growth appearing along the bottoms of the exterior stucco walls near the flowerbeds? What can I do about it?
» This may be colonies of mildew. These microscopic organisms are part of the natural lifecycle of organic matter, including decay and composting of landscaping plants and mulches. Excessive moisture in flowerbeds, shrubs, mulch and other organic materials creates ideal growing conditions for these organisms. Prevent or minimize, it by eliminating the excess moisture: be sure irrigation systems are not directed against walls and keep plants trimmed back to allow ample light and air circulation. Remove these discolorations from stucco surfaces by applying household bleach to the pre-wet surface followed by thoroughly rinsing with clean water before drying. Remember: always keep bleaches and other chemicals away from children, and ALWAYS use the proper safety equipment — including eye protection — when working with a hazardous substance.
