Tree Marigold
Likes a sunny but sheltered position in a range of soils, provided they drain well. drought-tolerant once established. Cut back periodically to promote flowering and to ensure bush doesn't become straggly. Prunings can be dug into the soil and kept moist during decomposition to deter nematodes. Scented leaves are effective as a pest repellent and deterrent for white fly and other harmful airborne pests.
