pachysandra

lily603(6)March 2, 2012

i had this problemm last year - spotted and yellowing on my pach. cleaned out, dusted with diatam.earth, and used neem. toward the end of summer noticed an improvement. here is it march 1st, not a bad winter at all, and pach. is showing the same signs. i have tried out extension service to no avail. last yr no help, no answer this yr. i need to find out a place to have my plant tested and figure out what i'm fighting against. i live in 19380 area (just west of philly). any help welcome

lily, one of the most common issues with pachysandra in your area is volutella blight - begins as tiny tan or brown spots that eventually merge together and kill an entire leaf.

Does your problem look anything like this?

how about just posting a picture ...

never heard of surface application of diatam. earth in teh heat of summer ....

nor late summer oiling ...

i would start with asking what kind of tree ...

how long have they been there ....

how do you water them ...

do you fert ...

are they near a lawn that is sprayed ...

etc ....

post a pic if you want to get anywhere with this. i doubt we can do much for you w/o such .. check out the link ...

to morz 8 saw that picture today. sure looks like my problem-a biiig one.
diam.earth:Diatomaceous Earth kills aphids, white flies, beetles, loopers, mites, snails, slugs, leaf hoppers, and harmful pests.
neem oil i used to manage fungus, neem is very effective at smothering insect eggs and soft-bodied pests such as aphids, mites and white flies.
what tree???

Lily, a thorough clean up of any leaves or debris, thinning the plants if necessary to increase air circulation, avoiding watering in later afternoon or evening so plants aren't spending a night wet...may help if its really volutella.
