Cape Honeysuckle Problems

Cape honeysuckle (Tecomaria capensis) is a fast-growing vine that is often trained as a shrub. It has few problems and is seldom bothered by insects if given proper growing conditions. Improper fertilization and watering are the sources of most problems encountered by cape honeysuckle.

Growing Conditions

Cape honeysuckle grows best in full sun, but it will tolerate partial shade. The plant is suited to most soil types, but good drainage is essential. It is winter hardy in USDA zones 9 to 11, reports the website Floridata.

Minerals

Cape honeysuckle is susceptible to mineral deficiencies, particularly nitrogen and iron, which cause faded, spotted, yellowing and distorted leaves. You may see fewer leaves and flowers, and severely deficient plants may die back. Waterlogged soil and harmful nematodes can mimic these symptoms because they prevent the roots from absorbing minerals from the soil. Over-fertilization--or adding minerals to the soil when they aren't needed-also causes leaf problems. A soil test will identify mineral deficiencies and tell you how to correct them. Contact your local Cooperative Extension Service to find out how to get a soil test.

Watering

Cape honeysuckle is a drought-tolerant plant and once established doesn't need regular watering. Too much water causes root rot as well as discolored and dropping foliage. Watering established plants near the trunk causes root and crown diseases, according to the University of California Extension.
