Protecting germinated Plumeria seedlings from pests involves implementing preventive measures. Keep the growing area clean and free from debris, as pests can hide in fallen leaves and decaying matter. If pests are a concern, you can use horticultural oil or neem oil, diluted according to the manufacturer’s instructions, to spray the seedlings as a natural pest deterrent. Avoid using harsh chemical pesticides that may harm the young seedlings. Regularly inspect the seedlings for signs of pest infestation, such as chewed leaves or visible insects, and take appropriate action if necessary. Protecting the seedlings from pests ensures healthy growth and minimizes potential damage.
