The large, showy flowers of the C.M. Wilson japonica make it a hit on show tables and in the landscape.
Containerized plants benefit from three or four applications spread throughout the growing season.
It's mild, about the same strength as fish emulsion, but even that can burn tender roots unless the plants are watered thoroughly before feeding. Also, many nurseries carry camellia and azalea food, which is an acid plant food, and that seems to work just as well. Just be careful you never exceed the dosage recommended on the label. Always water a day or two before fertilizing. The first application should be applied right after blooming season, normally the end of March.
