Insects, Diseases, and Other Plant Problems: Populars are not good landscape trees because they are suseptible to a number of pests and diseases as well as other cultural problems. Insect problems include aphids, borers, caterpillars and scale. Cankers are problematic especially in hot and humid climates. Cytospora canker attacks the upper branches of the tree and trunk and is often fatal. Dieback, leaf spots, rusts, and powdery mildew are other diseases problems. Weak wood is easily damaged by wind and shallow roots can lift sidewalks, make lawn mowing difficult, and damage drainage systems. Frequent clean up is required from the endless amount of falling leaves and twigs. To quote Michael Dirr from his popular book Manual of Woody Landscape Plants,"if anyone plants poplars they deserve the disasters which automatically ensue."
