    Could be
    Phytophthora root rot

    Phytophthora root rot is usually associated with poorly drained areas or other situations that result in periods of high and sustained soil moisture

    Where excess moisture is present Phytophthora or Pythium root and crown rot can become a problem on surviving plant roots. Since these fungal diseases often follow non-infectious root death, they are difficult to diagnose without laboratory analysis of the dying root tissue.

    Phytophthora or black vine weevil. These are two very common conditions for Taxus in our area. Talk to Doug at Lesco.

    Phytophthora or the weevil
    The weevil will show notches on the leaves.

    Take a sample to your local extension service for proper Identification

    Insects also could create frass that result in sooty mold, as the frass
    is a great climate for the mold.


    Black vine weevil larvae (Vis. 1) feed on roots, resulting
    in needle yellowing. Severe infestations kill the plant.
    The adults feed at night, notching the needles. Check
    needles near the center of the plant for notching.


    Taxus mealybug is 3/8 inch long and is covered with a
    white, waxy coating. The insect sucks plant juices and
    prefers dense plants. Heavily infested plants have few
    needles.
    Fletcher scale is a brown, hemispherical scale that is
    common on Taxus. Severe scale infestations cause needle
    drop. The preferred method of control involves regular
    inspection for early detection of the infestation then
    spraying with dormant oil.
