Northern Lights Azalea series are the hardiest. They grow from 3 to 6 feet in height.
In MN, they prefer sun during the growing season. While Rhododendrons prefer light to medium shade. You should avoid planting these on the south or southwest side of your house. The soil should be moist, well-drained, with plenty of organic soil. When you plant an azalea you dig a hole at least twice as wide as the container. Mix your existing soil with 1/3 peat moss. Place the plant in the hole so the top of the root ball is 2” above ground level. Backfill with the amended soil to the top of the root ball to create a slight mound. Fertilize with a fertilizer for acid loving plants. Chlorotic foliage ( yellow) may indicate that the soil is too alkaline and needs further acidification.
