Kumquat Overview
Kumquats are small evergreen trees or shrubs that produce tangy fruits with edible skins that are rich in vitamin C, vitamin A and potassium. A well-maintained kumquat tree can grow hundreds or thousands of fruits yearly. The flowers are fragrant and pretty. Kumquats are popular ornamental plants. The fruits can be used in various dishes, including salads, or made into marmalades, preserves and liqueurs.
Common problems with Kumquat
Root rot: Avoid excess moisture and make sure the soil is well-draining before planting. Avoid piling mulch around the base of the tree. Aphids, mites, scale, mealybugs, and caterpillars are also problems.
