Why Are My Ivy Leaves Dry?

Sun

• English and Algerian ivies grow best in partial to full shade and may become dry or sun scorched in full sun, especially in hot climates. Boston ivy tolerates more sun, but may also become dry in the heat. Plant ivy in partial to full shade, in moist, rich soil to avoid dry leaves. Houseplants grow best with bright, indirect light and cool conditions.

Disease

• Colletotrichum leaf spot is a fungal disease that causes dry, brown or reddish spots to appear on leaves. Sphaceloma leaf spot, or scab, may also cause dry, raised brown or gray spots. As the diseases spread, the entire leaf surface may be affected, making it appear dried and wilted. Remove dead or diseased plant material and spray with a fungicide if the disease is severe. Use soaker hoses or drip irrigation to keep the leaves dry. Wet leaves spread fungal disease.

Insects

• Aphids and whiteflies suck the juices from ivy leaves, causing the leaves to wilt, dry or yellow. The leaves may also have a white, stippled appearance. Spray the leaves with a steady stream of water to dislodge the insects, or use an insecticidal soap or horticultural oil. Spray the undersides of the leaves where the insects may hide.

Watering Frequency

• Ivy thrives in evenly moist, but not soggy soil, although it will tolerate some drought once established. Houseplants may develop yellow or dried leaves if given too little, or too much water. Water ivy when the soil feels dry to the touch and use a light, well-draining potting mix and a container with two or three drainage holes.
