Site Selection. Most holly shrubs and trees prefer a full-sun to light-shade location with moist soil that drains well. Varieties such as American holly (Ilex opaca: USDA zones 5 to 9) and yaupon holly (Ilex vomitoria; USDA zones 7 to 9) are versatile and shade-tolerant.
Holly Leaf Spot Symptoms. The symptoms of this holly disease are easy to see. Most types of holly plants will first show black, yellow or brownish spots on the leaves. Eventually, the leaves will start to fall off the bush. Typically, the holly leaves will start to fall off the bottom of the plant and work its way up the plant. Leaves will normally fall off the plant in the spring, but the spots will first appear in the late fall or winter.
