The answer to 'why is my garden' is that there could be several common causes, including poor soil quality, insufficient sunlight, improper watering, pest infestations, or disease. Symptoms may include stunted growth, discolored leaves, wilting, or lack of flowering or fruit production.
To troubleshoot the issue, start by assessing the soil pH and nutrient levels. Adjust the soil as needed by adding compost, fertilizer, or lime. Ensure your plants are getting the right amount of sunlight and water. Inspect for pests or signs of disease, and treat accordingly. If the problem persists, it's best to consult a professional landscaper or horticulturist who can provide personalized guidance.
