Step 1
Camellia efflorescence blight is a potentially deadly disease that will plough flowers chocolate-brown . The disease begins in early saltation , particularly in damp weather conditions . In early stage , camellia blossom blight starts as modest , brown place . The spots grow over time to cover the heyday . The prime will die in 24 to 48 hours . Remove all blossom that have been affected by camellia flower blight , and dispose of them instantly . The blight is due to a fungus in the soil , so clean away all mulch and debris around the plant .
Step 2
Fungus
Camellia flower blight is one of the agile and most deadly fungous diseases but not the only one that will turn heyday and foliation brown . Early root rot turns prime yellow before the full camellia flora begin to embrown and wilt . Root guff may cause the industrial plant to die quickly if it is not treated . Root rot fungus develops in soil where drainage is inadequate . Leaf gall often occurs in other spring when raw growth appears on camelia plants . youthful , newfangled leaves will become distorted and turn over pinkish or milky in colouring material . Later , the abnormal area of the leaves rupture and leave behind livid spores that harden and become brown . Leaf gall creates no substantial price but does discolor the industrial plant . take away all area of the flora affect by leaf gall , murder all fallen leaves around the flora and destroy it all .
Pests
Tiny scales feed on camellia foliage , sucking the nutrients right out of the leaves . Heavy feeding will break the plants and create wilt of the leaves and flowers . Tea exfoliation is particularly prejudicious to camellia . Early symptoms come along as yellow blotched on leaves . off all foliage affected by scales by hand , and treat the plant with pesticide .
Weather
When flower bud turn chocolate-brown and throw prematurely from the camellia works , bud drop is the perpetrator . utmost weather changes may lead to bud drop . Plant camellia in an area where they will not be too wet or too wry , and protect the plants from freeze weather . plant life camellias in partial shade to protect them from very hot sun in the summertime . Bud drop may also be because of pathetic soil drain or a want of nutrient in soil . Bright sun may also cause sunscald , which is something like a erythema solare on the plant life . leaf and flowers may look bronzed or burnt when sunscald occurs .
