Gardening Questions And Answers
Dark brown veins in the petals are a good indication that a camellia plant is suffering from petal blight. Pull off and dispose of infected flowers and treat with a foliar fungicide every one to two weeks. Canker disease can be identified by the sudden wilting of branches along with gray-colored blotches.
Camellias are hosts for a number of beetles, weevils, grasshoppers, caterpillars, and other insects that chew or consume plant tissue. The size, shape and location of the injury may help to determine the pest responsible. At least two different types of leaf beetles are known to feed on and injure camellias.
Do they need protection during heavy frost and low temperatures? Answer: Camellias are hardy and need flower protection only when the temperatures drop below freezing. Even then only the opening buds showing color are likely to be damaged. After the cold, the tight buds should continue growth and flower.
As a general rule of thumb, camellias, like most flowering shrubs, should be pruned immediately after they are finished blooming. This allows the shrub time to form new growth and flower buds before the next cycle of bloom. If you enjoy using camellias as cut flowers, you can even prune as you harvest the blooms.
Japanese Camellia oil is a rich source of Palmitic and Omega-6 Linoleic fatty acids, as well as numerous anti-aging polyphenol antioxidants. It is non-greasy and an excellent all-around moisturizer for the skin as well as for hair. Camellia oil is an excellent emollient for keeping skin and hair moist and supple.
If you see holes in your camellia leaves, the likely suspects are twofold: the black vine weevil, Otiorhynchus sulcatus, or the cranberry rootworm beetle, Rhabdopterus picipes. The adult beetles feed primarily at night while their larvae feed on the root system, making them difficult to identify and control.
Bear in mind that camellias are not particularly hardy, and can’t withstand very cold winters. In zones 6 – 10, they can be grown outdoors. In colder climates, try growing camellias in pots that can be moved outdoors in summer, then move them into the house to enjoy their flowers in the fall and winter […]
