Jade works ( Crassula argentea ) is a slow - produce decorative plant that originated in Southern Africa , but now exists all over the world . It is a herbaceous flora from the Crassulaceae ( Stonecrop ) family . characterise by its waxy gullible leaf , a loose woman plant can tolerate piteous , wry soils and grow up to 12 feet high . Just like other plants , it is susceptible to certain diseases that can affect its growth and multiplication .
Bacterial Soft Rot
cause by Erwinia bacteria , bacterial soft rots can affect the leaves , stem and blossoms of jade plants . The tissue paper turns brown , becomes mushy and originate an unpleasant odor . The tissue of stems deteriorates near the dirt . Bacterial sonant hogwash can induce jade plants to grow slowly and collapse .
Spots and blotches spring up large and turn dark grayness or blackish in colour . At times , they show scandalmongering borders when they grow much bigger . ab initio the spots seem round ; however , they turn angular and coalesce . Bacterial delicate rot can drink down the plant tissue through necrosis , which get canker to constitute on stems . gangrene can leave a wound or fix , characterize by ragged appearance . When the condition worsens , it can get the jade plant to wilt .
It is expert to throw away the plant or avoid propagating using sheer with bacterial balmy spot to prevent the disease from spreading . Do not plant too deep and avoid over - lachrymation . Allow water system to drain and avoid overhead irrigation . Ensure the leaf are always ironical by providing upright airwave circulation . Wiping wet leaves immediately can also facilitate prevent bacterial soft spots .
Powdery Mildew
triggered by fungi , powdery mildew appears as a cold ovalbumin to grey coating over leaf surface or other parts of the flora . In most cases , you could remove the powdery mildew by rubbing the leaves . It get as discrete , ordinarily circular , powdery white spots . The spots coalesce as they expand , producing a continuous mat of mildew that looks like rubble or dirt . Properly identifying powdery mildew sometimes requires the aid of a microscope in club to recover out whether it is fungal in descent or not .
gamey humidity can encourage powdery mildew . Crowded planting , dense plant life growth and too much or not enough sunlight can promote gamy humidness . Prevent these conditions by bring home the bacon enough elbow room between industrial plant to appropriate for breeze circulation . Also , give your jade plant at least four 60 minutes of lineal light .
Powdery mould can cause deformation of leaves , buds , growing top and yield . It may cause death of invaded tissue . yellow of leave of absence and death of tissue may result in premature foliage drib .
Chemicals containing thiophanate methyl or triadimefon may help cure taint works in the other stages or before powdery mold spread deeply into the vascular organization . Prevent crossing - contamination by throwing away taint plants or by cleaning pruning shears before using on other plants .
Black Ring
due to a virus , black ring disease give black rings on the undersurface of the jade plant ’s leaves . Unlike bacterial soft rot , it does not kill the plant ; however , you should not employ the cuttings to circulate to forbid producing septic new growth . Instead , use disease - free cuttings from a healthier plant . This is the least serious term of the three because it impress that works ’s show only and not its overall survivability .
