Fungi can attack irrigated plantings at any stage of growth, though most damage is on young plants. After germination, seedlings are susceptible to a number of root and stem rots, which become more prevalent in wet soils. The most common diseases are Fusarium, Rhizoctonia and Sclerotium , all capable of decimating young plants. Use a fungicide seed treatment where the incidence of soil-borne pathogens is known to be high and for irrigated plantings. Provides tall screen or leafy background in a hurry for temporary hedges, backs of beds and poolsides.
Seeds are extremely toxic.
