Holes in the soil around my rose
I have an Iceberg climbing rose.
It was purchased earlier in the year and about two months ago it started to shoot. All looked fine and as it shoud be.
Last week, it started to look like it was dying. The leaves were starting to drop off, and the stems appear black. I used some Bayer Rose spray, but that did not help.
On closer inspection, there are some holes around the base on the rose, going into the ground. The best way I can describe it is that someone has poked a 12 inch hole into the soil.
My assumption is that something may be burrowing and eating the rose? But I am not sure.
No other plants h=nearby are affected.
Can anythinh help with some guidance.
Thank you in advance.
