Bigleaf hydrangea is a summer blooming plant. It loves a moist but not poorly drained soil with lots of compost mixed in. Select a spot with bright, dappled shade or some early morning sun and afternoon shade for best results. Fertilize it every month to six weeks during the growing season with a product formulated for acid loving plants such as an azalea and camellia fertilizer product, applied at the label rates.
