To manage powdery mildew in Bulbinella nutans, ensure the plant is grown in a well-ventilated area and maintain proper watering to avoid excess moisture. If powdery mildew does appear, remove and destroy the infected portions of the plant and apply a fungicide as directed.
Another disease that can affect Bulbinella nutans is Sclerotinia rot. This fungal disease can cause the plant to develop water-soaked lesions on the leaves, stems, and flowers. Eventually, the plant wilts and dies. To manage Sclerotinia rot, avoid overwatering the plant, ensure adequate air circulation, and remove and destroy any infected plant material. Applying a fungicide may also be helpful in managing this disease.
Pest Management for Bulbinella nutans (Thunb.) T.Durand & Schinz var. nutans
Like many plants, Bulbinella nutans is susceptible to pest infestations. Here are some common pests that may affect this plant and how to manage them:

Spider mites are another pest that can infect Bulbinella nutans. These tiny pests suck the sap from the plant, causing the leaves to develop a stippled appearance and eventually turn yellow and drop off. To manage spider mites, ensure the plant is grown in a well-ventilated area and maintain proper watering to avoid excess moisture. You can also apply insecticidal soap or neem oil to the plant as directed.
Caterpillars are a third pest that may attack Bulbinella nutans. These small worms can eat the leaves and flowers of the plant, causing significant damage. To manage caterpillars, handpick them off the plant or apply a pesticide as directed.
