The answer to 'why is my landscape design' is that there could be several common causes, including poor planning, improper plant selection, drainage issues, or lack of maintenance. Symptoms may include unhealthy plants, erosion, standing water, or an overall disjointed appearance.
To troubleshoot and improve your landscape design, first assess the specific problems you're experiencing. If it's a matter of plant selection or layout, you may be able to make adjustments yourself. However, for more complex issues like drainage or structural problems, it's best to consult a professional landscaper who can provide expert guidance and solutions.
