The answer to 'garden turning brown' is that there are several common causes, including drought, disease, pests, and nutrient deficiencies. Symptoms may include wilting, discoloration, and patchy or uneven browning of the grass or plants. Fortunately, there are often simple solutions that homeowners can try before calling in a professional landscaper.
If the browning is due to drought, the solution is to increase watering. Make sure your sprinklers or irrigation system is working properly and adjust the schedule as needed to keep the soil moist. If the browning is localized, you may need to hand-water those areas more frequently. If the issue is disease or pests, you'll likely need to treat the affected plants with the appropriate fungicide or insecticide. Nutrient deficiencies can be corrected by applying a balanced fertilizer. However, if the problem persists or you're unsure of the cause, it's best to consult a professional landscaper who can diagnose and address the issue.
