Red leaves on Rododendron
I am hoping there is an expert amongst you on Rododendron. I planted 2 beautifully big plants in the Spring. They flowered and have new buds and have grown new leaves at the top but recently I have noticed that the leaves at the base of the plant have turned red - not all but some. Some leaves, red and green, have fallen, but not many. I also have azaleas they have some red leaves too but not dropping (I think this is normal as it needs to shed some leaves).
Is this normal for the Rodos? If not what is wrong with the plants. Is it too much rain after too much sun ( we did have a hot June and wet July).
what should I do to try to keep the plants alive?
thank you for your help.
Sounds perfectly normal.
Many Rhodos are evergreen.
This does not mean the leaves are everlasting.
It is quite normal for the older leaves to die and drop off.
If the buds and new growth is fine then try not to worry.
The roots are very shallow so to stop them drying out mulch them deeply with leaves or bought composted bark..keep away from the trunk.Give them a good watering first.
Make sure water cannot pond at the roots.
