The Q&A Archives: Azaleas

Question: I just planted 2 Azaleas. How long before they will turn into good size bushes. They get sun all day and plenty of heat.

Answer: Azaleas are woody shrubs which keep growing all their lives. Some varieties can get quite tall, into the tens of feet, while others remain spreading groundcovers less than 12 inches in height. Upright varieties tend to also spread out with age.

The rate of growth is a good predictor of the ultimate size. It can vary from around 2 inches to 10 inches in a season, depending upon the variety, the climate and other environmental conditions, primarily water, exposure, and nutrition.

Many of the sizes listed in books and catalogs are the so-called "10 year height", which can be used as a point of comparison. So, if you look up the varieties you've planted, you'll get an idea of their ultimate size.

Best wishes with your new azaleas!
