The Q&A Archives: Rhododendrons and full sun

Question: I bought two 4 ft. rhododendrons (English Roseum) from a woman who said they were raised in 'full sun'. I planted them in a full sun place in my yard. How can I ensure that they'll survive and thrive?

Answer: 'English Roseum' blooms mid-season, grows to about 6 feet tall, and is hardy to -25F degrees. It likes full sunshine, moderately acidic soil, and summertime watering. The flowers will be lavender with a yellowish green throat. To ensure healthy plants, mulch with peat moss to help the roots stay cool (and to help keep soil on the acid side), feed after flowering, and water deeply 2 or 3 times a year to help leach salts from the soil. (Excessive salts will result in brown leaf edges.)
