The answer to 'my garden looks bad' is that there are several common causes, including poor soil quality, lack of sunlight, improper watering, and pest or disease issues. Symptoms can include wilting, discolored or sparse foliage, and stunted growth. To address these problems, you may need to amend the soil, adjust your watering schedule, or treat any pest or disease infestations.
If the issues are more complex or you're unsure of the cause, it's best to consult a professional landscaper or horticulturist. They can diagnose the problem and provide tailored recommendations for getting your garden back in shape.
