I have what looks like mold (or some type of fungi?) growing around the base of these plants. Any idea how to treat it?
These are new plantings and shortly after I put them in the ground I noticed that some (most) of them were showing some brown spots and extreme yellowing on the leaves.
A guru at Home Depot told me that it looked like an iron deficiency and fungi, so I put some Hollytone around the base and sprayed them a couple times with fungicide.
I have no idea what is going on with these guys but I hate to lose them. I have some Aucubas nearby that seem to be doing very well. Any ideas??
Thanks!
