Rhododendrons perform best in regions with cool, moist summers. They bloom in late spring to early summer; flower colors include pink, red, violet, yellow, and white, depending on the species and variety. Size also varies considerably, from 1 or 2 feet to over 20 feet in height, so choose plants carefully to fit your garden situation.
Special Features of Rhododendrons
Plant in spring or fall. Space plants 2 to 6 feet apart, depending on the expected mature size of the plant. Dig a hole only as deep as the root ball and 2 to 3 times as wide. If your soil is in very poor condition, amend the soil you’ve removed from the hole with a small amount of compost. Otherwise don’t amend it at all. Carefully remove the plant from the container and set it in the hole. Fill the hole half full with soil, then water it well to settle the soil and eliminate air pockets. Let the water drain, then fill the remainder of hole with soil and water thoroughly.
