The answer to 'why is my patio dying plants' is that there are several common causes, including insufficient sunlight, poor drainage, soil compaction, and pest infestations. Patio plants may exhibit symptoms like wilting, discolored leaves, stunted growth, or even complete die-off.
To troubleshoot the issue, start by checking if the plants are getting enough sunlight - most patio plants need at least 6 hours of direct sun per day. Ensure the soil drains properly and isn't becoming waterlogged. Aerate the soil periodically to prevent compaction, and consider amending it with compost or other organic matter. Finally, inspect for signs of pests or disease and treat accordingly.
