Grown for its attractive foliage , cast iron plant ( Aspidistra elatior ) is aboriginal to China and grows in U.S. Department of Agriculture works hardiness zones 8 through 10 . This drought large-minded works does well indoors because of its easy nature and few serious problems . It can develop leaf spotting and root rot disease . The few fungal disease that can round cast branding iron plant are preventable with proper care and sanitation practices .
Leaf Spot Disease
Step 1
The leaf daub disease most likely to affectcast smoothing iron plantsis due to Fusarium kingdom Fungi , observe University of Florida IFAS Extension . The disease typically produces pocket-size , water - soak dots . As the disease progresses , the spots can blow up and evolve a yellowish anchor ring and red or brownish - colored center . Removing infected leaves and water at the base of the industrial plant — so the leaves stay juiceless — will help command this fungous disease .
Sclerotium Rolfsii Rot
genus Sclerotium rolfsii is a fungal disease that typically produce dark-brown lesions on the infected plants ' stem near the filth story . As the disease progresses , the leaves commence to yellow and die , and white mycelium form on the grime and septic plant tissue . grow the cast smoothing iron plant in well - enfeeble grunge will keep this fungal disease at bay . Avoid over - water the plant and or else keep the grunge evenly moist . quick - to - use liquified copper fungicide can help insure leaf spot disease and typically requires repetition app at seven- to 10 - day intervals .
Fusarium Solani Rot
This fungous disease will cause the leaf near the understructure of the petiole to decompose and pass from the flora , and the root word set about to melanise . Controlling this rot want improving the drain by either moving out-of-door swan iron plants to a spot with better drain or replanting indoor flora in well - drain growing medium . Another option is to spray the cast iron works with ready - to - economic consumption liquid copper fungicide once every seven to 10 days until the disease is no longer a job .
Consideration
The salutary defense against fungal diseases is bar , which can be execute with right ethnical guardianship . Because fungous diseases broadly occur when inordinate moisture is present , take care not to over - pee the cast Fe plant . To set if the cast iron plant life needs watering , stick your indicant finger several inches into the soil . If the soil feels moist , the plant credibly does n’t need tearing . If the soil feels dry , water the plant as you normally would . Healthy industrial plant are less likely to develop trouble and — if a problem does arise — are more capable of hold out with small to no serious damage .
