Gardenia crops are well known that contrast nicely with all the deep-green foliage. A variety of gardenia types exist, from low lying ground addresses to shrubs that achieve up to 6 feet tall. They are able to be a little high-maintenance, with relatively certain cultural needs although gardenias are commonly used in home landscapes. Even under ideal conditions, gardenias are vulnerable to aphids, especially whiteflies, scales, spider mites and several pests.
Whiteflies are small white bugs associated to aphids and scales. Females lay their eggs by sucking the plant juices from the leaves and all phases feed. Citrus whiteflies excrete a sticky honeydew that could cause sooty mould to to make on the leaves as they feed. Whitefly populations that are large trigger stunted plant development, as well as the leaves usually turn yellow, dry, die or drop in the plant.

Scales are usually mistaken by gardeners for infections or plant tissue. Scale populations can increase to substantial figures very rapidly as the women can reproduce without mating. Scales suck the sap causing the leaves to yellow, wilt, curl or drop off the plant. Gardenias that are affected expertise plant growth and create little flowers and leaves. Some scale species excrete honeydew, which encourages the development of sooty mould.
Green peach aphids and melon aphids are small, soft-bodied insects that usually prey on gardenia crops. Aphids stems generally cluster around rising buds and leaves to feed, piercing the plant tissue to suck the sap out. These bugs reproduce quickly to achieve harmful figures although tiny aphid populations usually do little harm. Feeding aphids trigger plant leaves to to look distorted or curled, stunt plant growth and decrease flower production. Aphids excrete honeydew, which in turn causes causes sooty mould to produce on leaves that are affected.
Two-Spotted Spider Mites
Two-spotted spider mites are small arachnids which can be hard to identify until their populations reach harmful figures. Spider mites feast upon underneath of leaves, sucking the plant juices out. This causes white or yellow speckles to to create on the surfaces of the leaves. Foliage that is affected frequently appears distorted.
