Yew hedges are a popular choice for formal gardens and privacy screens due to their dense foliage and classic appearance. However, like all plants, yews can encounter problems that affect their health and appearance. Recognizing these issues early and taking appropriate action can ensure your hedge remains healthy and beautiful.
Common Yew Hedge Problems
Pest Infestations
Yews can be affected by pests such as scale insects, aphids, and spider mites. These pests may cause yellowing leaves, stunted growth, or sticky residue on foliage. Regular inspection helps catch infestations early.
Disease Issues
Fungal diseases like root rot, needle blight, and canker can weaken yews. Symptoms include browning or discolored foliage, dieback, and oozing wounds. Proper watering and good air circulation reduce disease risk.
Nutrient Deficiencies
Yellowing or pale foliage may indicate deficiencies in nutrients such as nitrogen, iron, or magnesium. Soil testing and appropriate fertilization can correct these issues.
