White Roderdendrum .these were my mothers but she passed really quickly last September. I had her prized 2 roddys. Other one is growing new leaves so i no its doing fine had a couple of flowers on it but i put it down to moving and changing soil . But this one very sad too see it like this heartbreaking .same situation changed soil same position in sun watered the same everything but brown leaves looks nearly dead . Do i cut right back or treat it or just leave until end of year too see what happens .need some advice because its part of my mother thankyou any help would be gratefull .x
The other thing I wonder is if it could be something called red spider mite.
The leaf speckling is like we used to get on house plants. But I think it might also be able to thrive on an outdoor plant in the right conditions.
This is something you will be able to spray to treat or use a systemic insecticide on if it is.
It is just a suggestion to look up the signs and symptoms, as I am not sure it is.
Also to check if your plant is dying can you gently scrape a little bark off and see if it looks dead inside or if there is green healthy stem under it.
If you are not sure how it should look them do a little bit on the healthy one so you can note how it should look.
As there are two and one is okay I think the cultural conditions are the same. So it leaves a disease or insect vector attacking the second one.
It appears that d4go2u has treated them the same with same cultural conditions.
One is healthy and one is poorly....
Chlorosis /iron deficiency is leaf veins being green but the rest of the leaf yellowing?
Apologies if I have got it wrong.
The ailing plant has leaf speckling.
