This is a David Viburnum with a leaf issue.
This was planted in partial shade under a large fir tree until yesterday when I dug it up and put it in a pot in my greenhouse after discovering that all the buds had been eaten by the deer. The leaves began this odd discoloration shortly after I planted it in the garden soil about a year ago. I've tried increasing water and adding all-purpose plant food after it was in the ground for a while. I'm curious if anyone knows what is causing this and what to do for it.

David viburnums prefer more shade than sun. They can be susceptible to some pests too but I am wondering how the roots look? Overwatering can cause some leaf issues as the roots begin to die off and rot so usually I check the roots when a plant starts to look like this. I also use fish fertilizer once in a while because plants in the ground that are mulched are already getting nutrients as they mulch breaks down. You can overfertilize too-i have before i learned that nature has a way of taking care of plants in the ground and fertilizing does not really help them grow faster. It is unusual for deer to eat viburnums -so that is strange. do you see any signs of pests? I think you should change out the soil to a more organic -i like to use compost/manure in the bags for potting soil for my rescued and sick plants. Or if I find a root problem I take off all the dirt, clip off dead or dying roots, and then put it in a jar or container with fish fertilizer (about a capful) and let it re -root itself. I hope I helped.

That doesn't really look like a fungal issue to me, which is good news. The Missouri Botanical Garden says Viburnum davidii does best with consistent, even moisture, and I suspect it may not have gotten that competing with that large fir tree. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=d284

I feel that the issue is Gray Mold caused by removing it from hot , dry air and placing it in a humid area like your green house. It's not at all uncommon in my green house. Good to know it requires no treatment more than to place it in a drier environment and give it steady water.
