i have some box cones that are suffering from some disease, unlike blight the leaves show no signs of mold, no black spots or white powder, they are marbled in appearance with very fine yellow lines. the leaves turn brown and drop off.

could it be a type of miner, the tracks are very fine if it is 0.1mm if that.

please help they are not cheap

my plan at the moment is to repot feed well and shake away any dead material, any advances??

Hello Mike,

I'm not sure what is damaging your box plants. I think all you can do is to remove any affected material promptly wih clean secateurs and remove all dead leaves from around the base of the plants.

unfortunatly the best part of 75% of the leaves are infected but it does put out clear new growth.

thankyou for your time ill start cleaning and hopefully good hygene will help
