Potential fungus and die back on young maple tree #475718

Asked August 04, 2018, 9:58 AM EDT

Hi! I have a young maple tree that I planted in my backyard probably around 1.5 years ago. Before that it spent a good deal of time in a bag in our garage and then in a terracotta pot on our porch. I'm very attached to it as it is the last surviving tree we have from our wedding - we gave them out as favors. Its roots must have really gotten established over this past winter cause it has seemed very, very healthy this year. It has put on about 5 feet of growth and has full size leaves instead of the little baby ones it always put out before. We live in Virginia and we have gotten A LOT of rain over the past couple of weeks. We also have a sort of clay based soil in our yard. So anyway, all of the sudden the new growth at the ends of the branches is crinkly, crispy, and brown. I would assume that's a water issue but could that really be the case with as much rain as we've been having? Another thing I noticed when I was checking out the leaves was several small white dots on the trunk near the base. They seem slightly fuzzy and they come right off if I touch them gently. I actually called a local nursery and they suggested it might be crape myrtle bark scale. I looked it up and it does look pretty much just like that but can a maple get that? Any help is very appreciated. Like I said I am very attached to this tree and I want to make sure this isn't something that might kill it. Sorry for the one enormous paragraph. The entry form is being really glitchy and wouldn't let me start new paragraphs.

The white items on your red maple are Wax Scale. Here is a link to more information on them:  http://pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/444/444-622/444-622_pdf.pdf

Most of the plant looks healthy. The death of the tip leaves is very strange so you might want to bring in a branch tip that contains a dead leaf and some live leaves to mail to the disease lab. Here is the Suffolk Extension office information - they are without a Horticulture Agent right now but a Master Gardener should be able to help you process the sample to the Disease Lab in Blacksburg:

Thank you so much for the advice! I am very attached to this tree. It is the last living maple from a group that my husband and I gave out as favors at our wedding 3 years ago and I really, really don't want it to die.

Do you think there is any chance it isn't getting enough water? Or that the dead leaves could be from earlier in the season when we weren't getting much rain? 

I will definitely send a branch for testing. What is the cost associated with the sample?

There is no cost for the sample.  As for the dying leaf if its just one it probably is just a fluke since the other leaves in the pictures look fine and healthy.  Usually with water stress (too much or too little) you get wilting and then edges of the leaves brown and the furthest leaves from the roots dry up completely.

There are a lot of dry brown leaves. They seem to be spreading down two of the branches but I am not seeing this spread to other branches. I am still seeing new growth on the tree too. I'm going to get a sample to send in asap.

take a large enough branch sample with green leaves at the bottom and the dying leaves at the top to see if you might have verticillium or some other vascular disease.
