We built a large deck on the south-facing back of the house. The landscape plan called for four maple trees that would give some nice shade for the deck...some years down the road, since maples are very slow growers.
To get a jump start, we got the biggest trees we could afford on a fall clearance and even then paid about $200 apiece for trees that were a few measly inches in caliper.
Having spent so much, and taking the long view of what the trees would become, Mr. Jennifer wanted to really plant them right. He slaved for days with a pick in the heavy clay soil to dig four of the most beautiful holes I've ever seen, holes that would do justice to those giant burlapped root balls. He left loose soil at the bottom and planted the trees with dirt mixed with organic material. It was by the book. Our grandchildren were going to be climbing these babies in 25 years!
Over these years we have shaped them, given them regular deep waterings, and fertilized to encourage growth. The trunks seemed to grow imperceptibly. But finally, last year, the maples started sending up nice tall shoots.

Again this spring, my lovely trees began leafing out. Would we actually get some shade this year? All that money, all that care, all the time waiting would be worth it!
Well. Three leafed out beautifully. One did not. It sprouted a single branch of green leaves--while the rest of it appeared completely dead. I waited and watched. Surely it would leaf out! Finally we took a branch cutting to the nursery.
Introducing: verticillium wilt, my new mortal enemy.
What the heck is it?
"Verticillium wilt, caused by the fungus Verticillium albo-atrum ... enters plants through the roots and spreads systemically throughout the water conducting vessels. This plugs the vascular system, resulting in the familiar wilt symptom. Depending upon how much of the root system is infected and where the fungus spreads in the tree, the disease may be very mild or it may kill the tree in one year."Something I'd never even heard of and still don't completely understand is killing my tree.
How could I have known that verticillium fungus was present in the soil and silently attacking? That it was slowly poisoning the maple and cutting off its food supply, even as the tree looked so healthy and leafy in past years?
