Grow rhododendron in pots when soil is not acidic enough or too chalky or clay-heavy. If soil and weather conditions are optimal, opt to plant rhododendron in the ground for maximum growth.

Think cooler weather means it's time to pause planting? Think again! There is plenty you can do to improve your home and landscape during autumn.

Rhododendrons are hardy in USDA zones 4A to 8B. They're understory plants, meaning that they grow under the shady canopies of tall trees in their native habitat.
