Hi... We are in Perth . Recently we have noticed quite a few of our Agava , Yukkas ,Dragun tree and Dracaena have developed spotty leaves.
There does not appear to be any little creatures on the leaves and it is as tho the spots are inside the leaf..
The underside of the leaves are unaffected
What do you think the cause could be?
Hi Geoff
I am really not sure. Have you had a very cold, wet winter this year? There are reports of small 'crystal like' markings appearing inside the agave leaves after cold and wet winters. The plants seem to be unaffected and the new leaves grow without markings
