Hello,

I was curious if my azaleas look healthy. I just purchased them a few months back at my local nursery. They are mainly in part sun and part shade, but since the fall is here, they are getting more towards full shade. They are north facing. I do fertilize them with an acidic fertilizer specifically for azaleas. Once every week or two weeks.
Let me know your thoughts on anything I can do to keep them healthy. I may plant some annuals in there with them as the pots they are in are absolutely massive.

They look fine and healthy. Their root system is very shallow so I would not plant anything else with them.

Thank you for the replies. I also took the coleus out of the container earlier today to promote healthy root growth for the azaleas.

I would not think of Azalea roots as shallow. Having dug several of them up over the years, it's like digging up a tree.

Are these some kind of especially small Azaleas? An Azalea can get to be as big as a van.

Yes, rhododendrons and azaleas do tend to have shallow roots, some -taller variants- more than others but not much. The roots are very shallow with mature plants having a root system that looks more like a pancake compared to other plants. The general thought is that the roots will extend at least as far as the widest branches, possibly slightly farther... assuming the plant has not been pruned before. Some time ago, the Rhododendron Species Foundation had to transplant almost its entire collection, which included several very large rhododendron plants, and they had the entire root structure sandwiched between two shipping pallets which were about 7 inches apart. All you need to do to stop the spread of any rhododendron/azalea roots usually is to put in a metal barrier about 8-10 inches deep (useful when you salt the driveway).

Thank you for the info. The ones we dug up must have happened to be anomalies I guess. Now I wish I had taken pics of what sounds like unusual occurrences.

Thanks for the info Tiffany & Luis.

I have two Formosa azaleas in the pictures. I believe they are considered rhododendron.
I took a look at our database page Formosa Azalea (Rhododendron indicum 'Formosa') for the plant and correct me if I am wrong, but does the Formosa actually get that big? The database link says 6-8 feet in height and spread of 4-6 feet. Is that accurate? I have both of them in planters so I doubt they will get that big anyway. The planters are massive though so it may help in that area.

Depending on location and environment, it can get anywhere from 4' to 6' to 8'.

Thanks,
Also does formosa azaleas like shade? The guy at the nursery said only put them in pots if they are in full shade... He also categorized the plant as a shade plant. Is this true, because I have seen a lot of azaleas as full sun plants.

Full sun and partial shade are usually best for this shrub, meaning it prefers a minimum of 4 hours of direct sunlight. However, if summer conditions are harsh where one lives, provide afternoon shade instead.

Thanks Luis. It gets some morning sun right now and in winter months since it's north facing. Sun is brutal here in the Florida summer.
