Q.hibiscus not flowering
I grow hibiscus in summer and bring them in the garage for winter. I live in Ohio. When I bring them out in spring, they grow, but no flowers. What should I do?
Have you fertilized? They need nutrients to form buds.
Are they receiving adequate sunlight? Hibiscus need plenty of watering to produce blossoms.
Here are a few articles to review Hibiscus care.
