Where can I find slow-release fertilizer pellets specifically for flowering plants?
I have some pellets for acid-loving plants (which I use for my azaleas and hydrangia), and some for roses, but I cannot find any for general flowing plants.
I have begonias, petunias, hibiscus, lilies, sunflowers, butterfly bush, and others.
What type of balance do hibiscus need? Do they like acid or basic soil?
