cananga odorata with black leaves
Hello, what a sorry picture for a first post here. But having grown a lovely Cananga Odorata from seed for a couple of years it developed black leaves and died. It took ages to grow more seedlings, and now the same issue. The plants are kept at between 18-25 deg C, 80-90% humidity with fans to circulate the air. - the orchids etc love it, but when it comes to Cananga I have black fingers,
Any ideas folks?
