View Full Version : shrubs all dying.... HELP!

06-24-2007, 09:16 PM
A commercial client of mine has around 20 yews that have large portions of the plant turning reddish brown and dying off.

I can't figure it out, they have been getting enough water, and 70% of the plant looks great, but the 30% is completely dead! It started right after the winter and is getting worse.

Any help on identifying and solving this problem would be much appreciated!

Salt damage from winter?? possibly?

I dont know but I would check with the nursery and with my local extension department. Run a soil test.

They can get a type of borer that does that.

first thing to check after enough water, is if they were planted too deep, they cannot be any deeper than the original depth, any soil or mulch that is up against the trunks will slowly kill them. Make sure that the original soil height from the nursery is as high as the surrounding soil, no higher, all the way out to the drip line.

Don't have an answer , but I have several at one of last year's installs that are doing what you describe - first time I have ever seen that with yews - others on the same site are doing fine.

How long have they been planted? Are they mature or newly planted?

Yews are highly susceptible to poor drainage. Check that. However...

It sounds to me like damage from mice or voles under the snow, over the winter. They eat the bark off and affected branches are killed.

Ive had that happen due to exhuast from trucks sitting there running.

well from looking at everything you said, I would have to conclude that it is from rodents stripping the bark. that WVU link was very helpful!
