The answer to 'landscape design dying' is that there are several common causes for a landscape design to decline, including improper plant selection, lack of maintenance, pest or disease issues, and environmental stress. Symptoms may include wilting, discoloration, or thinning of plants, as well as overall poor growth and aesthetics. Solutions can range from adjusting watering and fertilization, to replacing diseased plants, to a complete landscape renovation.
In many cases, addressing a dying landscape design can be done through DIY efforts, such as pruning, weeding, and adjusting irrigation. However, for more complex issues like soil problems, major plant replacements, or redesigning the entire layout, it's best to consult a professional landscaper or horticulturist. They can properly diagnose the root causes and recommend the best course of action to revive your landscape.
