Curling leaves can indicate over or underwatering, or that the leaves are being attacked by a sucking insect. Aphids, whiteflies and scales are insects that commonly attack fruit trees. Inspect the branches and look for bumps (scales), or egg clusters, or adult insects. If you find any, try washing them off with plain water. If the problem persists, you might want to try horticultural oil (AKA summer oil). This light grade oil can be used on most plants to kill scale and other pests. Check the label to see if it is registered for use on citrus. To make sure it won't harm your tree, do a test spray on some of the foliage to be sure it won't burn. Horticultural oils should be available locally or from, Gardener's Supply Co 128 Intervale Rd. Burlington, VT 05401 1-800-863-1700
