Rose of Sharon Bush

Question

I would like to know the best way to grow a Rose of Sharon bush in Michigan – zone 5. Best fertilizer, watering requirements, hours of sunshine per day, etc.

Answer 1

Rose of sharon is a very easy plant to care for. They do best in full sun (6+ hours) but will do fine in part sun (4-5 hours) and can also manage somewhat shady conditions. After they are established, they need almost no fertilizing or extra water, but if you are concerned they are not getting enough or either - you can give them a balanced fertilizer once a year in the spring and they need 2" of water a week, but are rather drought tolerant.
