Azalea & Rhododendron

Azaleas With Yellowing Leaves

I have four identical Azaleas, kept in the original nursery containers and ready to plant into containers. One of the four plants is rapidly turning yellow. The first photo shows the yellowing plant. The second photo shows one of its sisters, still very green on top with much less yellowing on the bottom.

Is this a sign of overwatering, or would it be normal die off in Winter? We are getting nighttime temperatures of around 40F to 46F.

I suspect the pots went drier than you realized some time ago.

Are they well hydrated now?

A thoroughly moist rootball will be heavy. Dry, rootball or drier, will be light weight.

If you suspect they are dry, submerge rootball in water.

f bubbles rise to the water surface, they're dry. Soak for a max of 30 minutes, then drain.

They are getting some rain, and they are moist to the touch on the top, which means they are even more moist near the roots. They are on an irrigation system and were thriving for most of the summer.
