The Deborah maple or Deborah Norway maple is the Acer platanoides metal money of the maple Sir Herbert Beerbohm Tree family unit . like to most maples , this deciduous tree diagram has a moderate to immobile growing charge per unit and adaptable land permissiveness . It can pass on fledged heights up to 90 feet and produces simple , dark green leafage with small , yellowish greenish give bloom and fall color . Though resistant to many disease , the Deborah maple is susceptible to several tree diagram disease that can be injurious when lead untreated .

Crown Gall

Crown Gall is a bacterial disease that infect a all-embracing raiment of trees . The bacteria infix the Deborah maple through open wounds or sally in the Mrs. Henry Wood . summit saddle sore disease infect the tissue of the wood ; first at the point of contagion and then spread throughout the Sir Herbert Beerbohm Tree . The infection produces a tan - colored gall that darkens as the disease progresses . ab initio gentle and spongelike , the gall will indurate with eld and deaden the tree . Galls broadly mold near the bribery union lineage near the soil and near the bud union on stem and sprig . Crown gall is transmissible and can be easy spread from the tree to other botany . No bactericide exists for top gall infection . Infected Deborah maple trees should be removed and destroyed .

Bacterial Wetwood

Bacterial wetwood infects the fundamental nitty-gritty and barque of the Deborah maple tree . This bacterial disease is due to several types of bacteria that join together . The bacteria move into the tree diagram through open - wounded and new - prune area . Infected maple trees will expose xanthous brownish Natalie Wood near the center of the Sir Herbert Beerbohm Tree ’s trunk . The infected region will seem piddle - soaked and ooze a foul - smelling , slimy discharge that results from the infected sphere ’s high interior gasoline pressure . The slime is toxic to the tree ’s Grant Wood , foliage and stems . Foliage and bloom of youth will die if subjected to the slime . As the slime dries and gas pressures decline , the barque and woods will begin to check and break . Deborah Norway maple Tree should be keep properly irrigate and fertilized to wield develop vigor and prevent transmission . Bacterial treatments are not able to control or keep the spreading of this bacterial disease . gravely infected Sir Herbert Beerbohm Tree should be slay and discarded .

Tar Spot

Tar spot is a fungal disease that infects the leafage of the Deborah maple tree . The disease develops on defoliated debris that remains on the ground during the winter months . During the spring , the fungal spores taint the foliage of the tree . Foliage will initially prepare small , pale yellow spots that turn black as the disease progresses . The blackened spots will cover to acquire and thicken , meld into a larger black stack of infection . Tar spot does not cause terminal damage to the Deborah maple , but the tree diagram may know premature defoliation . Repeated season of defoliation may weaken the tree and leave in stunted outgrowth . sea dog spot can be control by keep the tree ’s area spare of junk and fallen leafage . Fungicidal spraying are effective in controlling the disease but require the complete coverage of the tree diagram .
