Q.How to save my holly bush
Transplanted in spring. Fabric mat and stones added in the area around the bush. It was doing great and suddenly the leaves are all turning yellow. It looks like it is dying. The soil is moist and the new location is 2 feet from the old.
You could have a few issues going on here. If it has been hot and dry this new shrub may be needing more water.
Newly planted this spring it may not have the root structure to hold up to warm summer temperatures yet.
Yellowing leaves can indicate watering issues. Either to much or to little.
I also see some insect webbing in the image. This could be Spider Mites.
I would trim away the dead material and dispose of. Increase watering if it is dry.
Treat the Holly with Neem Oil, as use weekly for the remainder of the growing season.
