Hi,

I have Tauntoni yews(Taxus Tauntoni) and Browni yews which keep turning
yellow & brown and dying whereas the daisies in the same area seem to be
florishing and spreading like weeds. Is this because of the local soil
condition. Do the yews need more acidity? Would some fertilizing help?

I live in Michigan, the soil is clayey and the area gets plenty of sun
during afternoons.

Any help is appreciated.

These yews are usually long-lived and generally considered a
low-maintenance shrub with no serious insect or disease problems so
don't bother with an herbicide or insecticide. They may wilt and die if
grown in heavy, poorly drained soils. Foliage may brown in winter
(winter burn) from exposure to dry winter winds. Twig dieback may occur
in winter or at other times in the year as a result of damage caused by
sudden and extreme winter temperature changes. These varieties are
noted for having better resistance to heat stress and to winter burn
than most other yews.
