Plant Quick Fire Fab® Panicle Hydrangea in well-drained soil with full sun to partial shade. Space plants 6-8 feet apart. Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer. Prune in late winter or early spring to shape and encourage new growth. Protect from harsh winds and extreme temperatures.
