Coral bushes are actually quite resistant to diseases and pests. Nevertheless, they can sometimes be affected. Then fast action is important.
The exotic coral shrub is relatively insensitive. He is reissuing every year. Thus, pests have little chance. Occasionally, however, aphids, spider mites and white flies emerge. But that does not matter, because the parasites can drive you out by various means.
For diseases, the coral shrub is also hardly susceptible. Due to care mistakes but it can lead to deficiency symptoms.
Pests on the coral shrub
Look closely as you water your coral shrub so you can quickly spot the annoying pests.
Aphids sit on the leaves. They are actually very good to recognize. A good and effective immediate measure: Spray the shrub with the garden hose. Put potted plants in a garbage bag and pack them in a watertight manner so that no pests are flushed into the ground. With it you expel the pests again. For aphids also help proven home remedies such as nettle (see instructions here) and a Schmierseifelösung. Mix 500 milliliters of water with a tablespoon of spirit and a tablespoon of soft soap and spray the plant with dripping wet water.
❍ spider mites:
Spider mites make themselves felt with a delicate white web in the leaf axils and small yellow dots on the leaves. Stinging nettle helps as well. As an alternative, you can also make garlic or onionsauce. For this purpose, chop onions or garlic, pour hot water over them and let stand overnight. Sprinkle the plant with the broth for several days in a row.
❍ White flies:
A white flies infestation can be recognized by the fact that the leaves turn yellow, dry up and finally fall off. On the leaves can also form a mushroom. The so-called Rußtaupilz shows up with tiny black dots. Despite the name "whitefly", the pest is not a fly, but a subspecies of scale insects. Adult white flies can be fought with yellow boards (available here, for example). The tablets are covered with a sticky liquid and attract the parasites. However, the pests can not be completely expelled. In addition to adult flies, the larvae also damage the leaves. In addition, plants in the neighborhood are also endangered.
With a strong infestation with white flies often only the grip to the chemistry remains. But then make sure that you buy a bee-friendly agent.
Spider mites, aphids and whiteflies have natural enemies: parasitic wasps, gall bladderwhips, lacewings and ladybirds love the parasites. So if you spot such insects in your garden, the pests have little opportunity to spread.
Diseases and care mistakes with the coral shrub
❍ root rot:
Compared to most diseases, the coral shrub is resistant. With waterlogging in the soil, however, root rot can occur. Behind it hides a fungus that rots the roots. The result: the plant stunted. To remedy this situation, you should dig up the shrubbery, completely remove any infected root parts and soil, and let the rhizome dry. Then put the coral shrub back in. Pay attention to a good permeability of the soil and put in the pot drainage.
❍ too much fertilizer:
The coral shrub is also sensitive to too much fertilizer. Use fertilizer only moderately in the flowering phase. Always mix liquid fertilizer with the irrigation water and never pour directly into the soil.
