As the photo shows,my Rhody has gotten very sunburned before I
had a chance to move or cover it so the last few weeks it's been
deteriorating health-wise,even though it's been moved into almost full
shade and kept moist..I have not used any additives or fertilizers. Any
ideas and suggestions will be appreciated.
I don't know of another group you could try. I didn't post earlier because I
thought someone with more gardening experience would give you advice.
However, I'll give you my two cents if no one else will.
I've had rhodies burned nearly as badly as yours appear to be. They
recovered when left in place. Moving yours was probably an additional
stressor. Now the plant is dealing with settling into a new spot as well as
burned leaves. Let it alone for a while. Rhodies prove to be pretty tough,
in my experience.
This is an appropriate place to ask this question, yes. However, your
plant is not sunburned. It defnitley has some kind of fungal
infection, most likeley phytophthora. Unfortunatley at this stage you
really have no option other than removal of the plant. Since the
pathogen is soil-borne, I would not recommend planting another
rhododendron in that spot.
I didn't mention that it is in a very large planter so moving it was
simply a matter of sliding it into the shade. The temp here was in the
high 90's low 100's for about a week and that's when it started to show
what I thought was sunburn damage,my other Rhody which is in another
planter but always partially shaded shows no signs except where the
direct sun hit it so I'm hoping Toads analysis's is hopefully
I didn't reply because I am way too far south to know about these plants and
have never owned a Rhodo in my life.
But it looked a lot like simple heat stress to me- and hearing that it is in
a planter box certainly doesn't change my thoughts.
The wilting and rolling of leaves is not sunburn, it looks terminal if
you are in the northern hemisphere. The browning can be sunburn or
The wilting and leaf roll can be one of the following:
Lack of soil moisture
Too much soil moisture
Root damage from high root temperatures. If the sun hit the large pot,
it could have cooked the roots.
The actual damage is dehydration. The cause can be diseased roots,
damaged roots, or dry roots. Wet roots can cause diseased roots. High
soil temperatures can cause root damage also.

Thanks Stephen,I guess I'll just have to wait and see if it
recovers..maybe I over watered after the sunburning but it's been so
A neighbor said she'd read a large can of tomato juice poured around
the root base may revive it..she'd read it in an old-folk gardening
