The aptly - refer " Autumn Blaze " maple ( Acer x fremanii ) is a hybrid between the tight - mature silver maple ( Acer saccharinum ) and the showy red maple ( Acer rubrum ) . The loan-blend has the profligate growing of silver maple without the argent maple ’s infirm branch structure and inherited intense nightfall color from its red maple parent . Poplar Farms of Illinois usher in the fall blaze away maple in 1982 and householder squeeze the fresh variety for the improved characteristics . However , certain diseases can affect any maple , including fall blaze .
Anthracnose
homeowner mix up anthracnose with singe , as both problem make brownish , dry leave and can defoliate a tree . Drought and gamy wind cause scorch along leafage edges , but anthracnose discoloration occurs along the vein and in queerly - shaped splodge . The University of Rhode Island Horticulture Department admonish that wet and nerveless springtime weather encourage the spread of anthracnose spores . The USDA Forest Service suggests spray a fungicide on freshly - open up spring leave-taking , with two repetition treatment two weeks apart .
Verticillium Wilt
If branch abruptly droop and perish , verticillium wilt disease may be to pick . In a intercrossed - like autumn blaze maple , the condition may not be severe and the only symptom may be a thin , tardily - growing crown . In pathologic branches , the woods under the maple ’s bark has European olive tree or hoary - super acid streaks . No cure exists for verticillium wilt , but Purdue University Extension suggest homeowners cut back out diseased wood and properly fertilize a maple to delay the disease . A fungus in the territory causes verticillium wilt , so never remove a maple and replant another maple — the disease is still present .
Root Rot
Verticillium wilt is not the only suspect if an autumn blaze maple demonstrate a thin crown . The University of Illinois Extension says armillaria fungus commonly infects maples , resulting in yellowing leaves , early leaf drop and weak tree diagram . Thin , white plane of the fungus are seeable under the barque at the bag of the maple and may smell like mushrooms . An autumn blaze out maple takes years to break down from tooth root rot , slowly declining over each season . Like verticillium wilt disease , a fungus in the land make root decompose and a diseased tree will not recover . Water maples during drouth , avoid root price , fertilise if necessary and control right stain drain . Again , do not replant a maple in diseased soil .
