Hi, I have a crepe myrtle in Adelaide that has some burnt leaves. I don’t think it’s a normal autumn browning. It’s not impacting the newer growth as much. Any idea what this is?
I’m watering twice a week on drippers.
Without a photo Nick, its difficult to diagnose but it could just be sunburn if you have had spells of hot weather in Adelaide. The fact that the new growth is OK is most encouraging.
