my problem is now, waiting for the summer months but for now my "Rosa sinesis, Baja Breeze" (Tropical hibiscus) is now inside for the winter months. But during the summer, i found that my hibiscus wasn't preforming like the pictures, and the sizes aren't that dramatic, like the pictures. i have good pro-mix and out-side all summer month, and i also occasional feed it, what about winter months? and is pruning all that nessassary? i want a larger Bush not small..
