Inspecting the Plumeria plant is important to ensure it is healthy and free of any potential issues. To do so, check for healthy, green leaves without spots or discoloration. Look for any signs of pests like webs or holes in the foliage. Avoid purchasing plants with wilting or yellowing leaves, as they may indicate stress or disease. Examine the stems and roots for any signs of rot or damage. It is best to buy from nurseries or suppliers known for providing healthy plants.
