We have a Japanese Lace Maple tree, and its condition has been declining for some time. It has been watered, but we havent really fertilized it. The leaves have turned brown and drooped along with the branches. The lack of fertilizer I think may not be the problem? There is a condition too that leaves turn brown because of a chlorodic disfucntion. Right now, there isnt much telling whats wrong.

Our tree is meant to be in full shade, just like how it is now

First of all where are you.Alot of areas in texas are getting more than normal rain.Don't be confused about too much water and not enough.In n.e.texas too much is the problem.And this is why leaves are turning crispy brown because of a fungus.Thus,this crispy effect on the leaves makes one think,Hmmmm,not enough water,so, they water more and make the problem worse.Also is it getting too much sun.But again I need to know what zone your in to judge what the problem is.Not enough enfo.

My tree got Verticillium wilt, also. The disease lives in the soil and infect the tree. Mine probably came airborne or came with other plants I bought. Basically, it clog the tree's its pumping system and the branches start to die off. You can tell by looking at the branches. It turns to black. That's why this is sometimes called, Black twig disease. I never fertilize my maple tree and they don't really need to be fed, by the way. Water is the most important thing for them. Unfortunately, you can do much about this. Do not try to transplant it, because you might infect the other plants you have. It won't get every plants, but you want to be safe. Perhaps, you can cut the sick part, and see what happens. Good luck!

How old is your tree? I've found a lot of the problems with trees planted from containers, is that the root ball is bound up and choking itself. Nurseries leave the young trees in the containers too long, and the roots are not loosened up before planting. The tree will do fine for 5 or 6 years, but then as the roots get larger, they start growing across themselves. This cuts off a large amount of the food supply. If this is the case, not much you can really do but start over.

You may have verticillium wilt. This is a serious fungal disease and it often hits maples among several other woody ornamental plants.
The disease can hit one stem at a time, or one side of a tree. Other symptoms of Verticillium wilt may include: marginal browning and scorch of leaves, abnormally large seed crops, small leaves, stunting, poor annual growth, and sparse foliage.
The way to determine the presence of the fungus in the field is to cut a small, dead branch off the tree. Cut it at a long angle to the expose as much pith as possible. Look to the cambium and xylem layers just under the bark. If they show distinct visible streaks or spots, generally grayish green, to olive or darker blackish green in one or more growth rings it is likely you have the fungus in this branch but a it should be verified in a lab.
The fungus enters through the roots and proceeds up water channels blocking them so the tree becomes more susceptible to heat and drought stress. It needs a steady supply of water to support growth. Sometime a large healthy tree will grow faster than the disease kills it if other stress factors are controlled. http://counties.cce.cornell.edu/suffolk/grownet/tree-disease/vertwilt.html

Fetilizing can make the problem worse. Cornell labs say " Wilt severity is increased by "high- nitrogen" fertilization and reduced by the use of "balanced" fertilizers having analysis such as 10-10-10. Fertilize as necessary to maintain N-P-K balance in the soil (i.e. supplies of available elemental N, P, and K having roughly a 2:1:2 ratio)."
