Pachysandra is susceptible to leafage blight – also referred to as Volutella blight or dieback . leafage blight is a fungous disease because of the Volutella pachysandricola fungus . Overcrowded beds are loosely affected . This fungal disease can pour down large area of a pachysandra groundcover bottom . It generally attacks rickety or hurt plant
Plant Characteristics
Pachysandra ( Pachysandra terminalis , a member of the Buxaceae – Box – family ) is also usually known as Japanese Pachysandra or Japanese Spurge . It is an herbaceous perennial evergreen groundcover of medium size . Pachysandra ’s maturation drug abuse is mat - like , and slow growing . It arrive at approximately 10 inch in height , and spreads by basal shoots . It is hardy in zones 5 to 8 .
Site Selection is Important in Preventing Disease
Site pick is important to the health of the plants . Pachysandra does well in organically plenteous , well - drained acidic soil – it will tolerate grease that has a pH that is neutral / slightly alkaline as long as it drain well . leafage blight thrives in stiff territory conditions – especially at sites that are not well - drain . Also , plants require a situation that receives partial to mysterious ghost ( prefers full shade ) . They become stressed when they have too much sunlight . Since keep the wellness and vigor of the pachysandra is the adept defense against disease , apply care in pick out a website that fills the pachysandra ’s key needs .
Leaf Blight
leafage blight of the pachysandra flora is a fungous disease because of the Volutella pachysandricola fungus . It is a devastating disease that can demolish big areas of a pachysandra bed . The first sign of this fungous disease is the appearance of tan to brown ( with dark dark-brown margins ) blotches on the septic leaves . These blotches then become larger , and canker can be get word around the shank and offset of the plant . As the disease progresses , the plants wilt and then snuff it . This disease unremarkably occurs under warm , cockeyed and humid conditions ( late spring and summer ) .
Plants That are More Susceptible
Plants that are stressed / rickety or injured are more susceptible to leaf blight ; therefore , it is significant to monitor and provide necessary corrective amount to maintain a good for you groundcover bed ( intelligent plant tissue is easily able to fight off disease ) . Pachysandra can become stressed when it has been injured during the winter season ( by de - icing salt or wintertime winds ) , during a drouth , when it receives too much sunlight or when it has been invade by insects . Other factors that encourage foliage blight are : very dim growth , which limits breeze circulation , and great mulch app , which confine drainage . These broker further conditions conducive to leaf blight .
Keeping Pachysandra Healthy
