Sedums are repeated flowering plants with succulent foliage . Many different eccentric of sedums exist , some growing to only 2 inches magniloquent and others reach out 2 substructure or larger in height . Sedum blossom gloss depart in shades of clean , yellow , pinkish and crimson .
sedum are low - maintenance plant that are susceptible to only a few fungal diseases , most of which are prevented by planting the sedum on well - enfeeble soil . TheUniversity of Florida IFAS Extensionrecommends only occasional watering for sedum , because too much water promotes disease . The remedy for how to hold open decease sedums suffer from disease , however , is n’t often potential .
Stem Rot Sedum Fungus
Stem bunkum disease is due to the fungal pathogen Sclerotium rolfsii and is one of the most uncouth diseases that affect sedums . Stem decomposition causes the sedum ’s lower leaves to work jaundiced and white , cotton - alike outgrowth of mycelium to appear around or near the crown on the soil . Eventually , the whole plant will droop and die .
handle stem rot can be hard and in severe cases may involve exchange all of the soil . Control stem bunk in the sedum by cut away and destroy all the diseased or diagnostic plant parts .
Basal or Root Rot
Basal rot is triggered by the fungous pathogen Rhizoctonia solani. This fungus rot and collapses the basal stems and turns them black or brownish . ancestor rots are make by Fusarium fungal pathogen and produce exchangeable symptom that are more centralised in the sedum ’s theme . Most fungicides are not good in treat either basal or root bunkum . take and destroy sedums infected with these types of rotting .
Powdery Mildew on Sedum
Powdery mold ( Erysiphe spp . ) causes white powdery spore to cover the sedum ’s leaf . TheUniversity of Massachusetts - Amherstnotes that powdery mildew may be confound with leaf slur disease at first glance . However , a close look reveal white fungous threads that are characteristic of powdery mildew .
This fungous disease is most rife during humid conditions when there is footling rain . Treat powdery mold by applying an appropriate fungicide , such as atomic number 19 hydrogen carbonate , triadimefon or thiophanate - methyl group , to your sedum according to the direction on the label .
Sedum Leaf Blotch and Spots
Several different leaf spot disease can infect sedums , admit those because of fungal pathogens in the Cercospora , Colletotrichum and Septoria genera . lesion or brown spots on sedum leaves that lead to disintegrate or necrotic speckle come about most often during wet conditions . How to treat sedum leafage spot is best attain by use a preventive fungicide such as thiophanate - methyl .
Sedum Botrytis Blight/Gray Mold
Gray mold , also know as Botrytis blight ( Botrytis cinerea ) , is a fungal disease that causes a fuzzy gray mold to spring up on the sedum ’s damaged or honest-to-goodness prime and leaves . The grey mould spreads to the healthy plant region as the disease progress . Gray mold disease is most prevailing during cool , wet environmental consideration and when old bloom or damaged plant parts remain on the sedum , provide an entry point for the fungous pathogens .
Remove all the dead or die flowers from the sedum to prevent gray mould . If your sedums are already infected with grey-haired mold , apply an approved fungicide like thiophanate - methyl group .
Sedum Rust Disease
Rust diseases are due to several fungous pathogens belonging to the Puccinia genus . Sedums with rust disease have powdery and rust - colored spore maturation on their leave and stem with yellow border plant tissues . Control rust disease by use an appropriate fungicide to your sedums , such as mancozeb or sulfur .
