This plant have brilliantly - colored blush in almost Ne shades of orange , yellow , pink and purple , as well as a creamy snowy cultivar . The Kalanchoe is aboriginal to Madagascar and is most often grown in the United States as a houseplant , accord to Dr. J. Raymond Kessler , a plantsman with Auburn University . While comparatively easy to care for , this woody shrub can support from a few diseases .

Powdery Mildew

Powdery mildew is a disease that often affects kalanchoe . This fungal disease flourishes in the warm , humid environment required by the industrial plant . In most shrub , powdery mildew manifests as a ashen , powdery coating that report the leaves and twig of the plant . In the display case of kalanchoe , however , very okay webbing develops between the leaves and staunch , according to Millie Davenport , a horticulturist with Clemson University . The leaves of the works may also develop spots or stagnant area . New blooms may be disfigured , or the plant mail fail to bloom at all .

Powdery mildew can be prevent by water carefully to avoid acquire water on the leaf , as the fungi that cause powdery mildew travel on water . Make indisputable there is lot of line flow around the plant also , as this will help quickly dry up any stray moisture lingering on the leave . If powdery mildew is still a job , an diligence of a fungicide containing potassium bicarbonate can aid control the disease , harmonise to Davenport .

Phytophthora

Phytophthora is a disease that sometimes affects kalanchoe works , accord to Dr. Kessler . This fungus subsist in the soil and prosper when the ground is kept continually wet . For this reason , kalanchoe plant should not be leave sitting in very wet dirt , or watered too often . The fungus attacks the roots , moving up into the kalanchoe and killing the interior part of the works . The kalanchoe will start to show signs of decline , with wilt , yellow parting and bloom that drop from the industrial plant before opening . Death of the plant life can be sudden or gradual .

This disease can be prevented by establish the kalanchoe in well - drain planting medium , such as a mixture that contain a large amount of peat moss and sand . In gain , stand water should never be lead in the water pinch - tray , and any container used to house your kalanchoe plant should have drainage jam .

Pythium

Pythium is another ground - expect disease that attacks the theme of decorative plant , including the kalanchoe . Unlike Phytophthora , which travels quickly up the plant to kill the crown and branches , Phythium remains focused on the ascendent , rotting the root hairs that ingest nutrients . The lower leaves of the kalanchoe will start out to turn chicken as they die from lack of nutrients and water . Over metre , the leave of absence higher on the plant will also commence to turn yellow and shrivel up . finally , the works will die as the roots become altogether unusable .
