Help! Last Sept/Oct I planted 15 yew shrubs in a semi shady area. I improved the clay soil with amendments. They seemed to be doing fine until a month or so ago when one turned completely yellow, then another. The rest are begging to turn yellow at the tips. It doesn't appear that they are losing needles though. I live in New Jersey Zone 6. We had a wet and cold winter. Are my plants dead? Is it some sort of insect infestation? Are they just dormant after a tough winter? Help! I don't want to loose them all!

hi tabeyer i don't have much of an answer for you, but wanted to welcome you. we do have folks who will come around who should know, so keep checking back. i did find out that from Bill, THE GARDEN HELPER, (he was doing some research) that they are suceptible to spidermites which will cause yellowing. i know there are other causes also, but i don't know what they are. i don't grow them due to the toxicity.
anyway, welcome to the garden helper, and hope you enjoy it here. let us know how it works out.

Even if you amended the clay soil, there is that possibility of poor drainage. Yews don't like their feet wet. Waterclogged soil will cause "Chlorosis" or yellowing of the leaves.
Yews are almost resistant to insect pests and diseases.

I agree with the two above posts, but also want to add a possibility. It could be salt damage.
Not too many bugs bother yews. Spider mites could do some damage but it is the wrong time of the year for them in your area.
Most of the time if there is a problem with a yew, it is cultural for example, planting too deep, or fert burns. Also you may want to check the base of the plants to see if anything has been gnawing away at the bark over the winter, as voles love them!
