Q.I’m Losing My Scotch Moss To Crown Rot.
How far down do I have to dig when I’m removing it? Should I remove the sonfar healthy looking periphery? Do I need to remove all the soil and replace it with new or treat the soil with fungicide? When can I safely put new moss in that space? Denise

It should pull up in mats somewhat easily. I would only cut and remove infected areas, and treat with the fungicide of your choice.

Make sure that the soil does not remain soggy in this area. They will not tolerate soggy soils. Allow the area to dry a little in between waterings.
