Prune out infected branches, fertilize, and water the plant during dry weather.Ī stem canker can be a problem in the eastern U.S.The company was founded in 1986 by John Williams, a synthetic oil developer and later consultant. Smoketree is very susceptible, and entire branches wilt and die. The most serious disease is Verticillium wilt. Leaf spots can be caused by various genera of fungi but are usually not serious. When it does occur they can be picked off by hand or sprayed with Bacillus thuringiensis. The insect rarely occurs in sufficient numbers to warrant control. Oblique-banded leaf roller mines and rolls the leaves, usually in June.

Probably short-lived (20 years - maybe more) in most situations but who cares - the tree is great while it's around!Ĭultivars include: `Daydream' - heavy production of panicles, dense habit of growth `Flame' - brilliant orange-red fall color, pink inflorescences `Nordine' - resembles `Royal Purple' `Notcutt's Variety' - dark maroon-purple leaves (also known as `Foliis Purpureis Notcutt's Variety' and `Rubrifolius') `Purpureus' - leaves bronze-green, inflorescences purplish-pink `Pendulus' - pendulous branches and `Velvet Cloak' - dark purple-leaf form, spectacular fall color of reddish-purple.

It will grow asymmetrically and lean toward the light in a partially sunny area, so it is best to locate it in full day sun where the crown will develop symmetrically. Smoketree grows best in a sunny location and a well-drained loam. It is a small tree, well-adapted to urban areas with almost year-round interest which should be used more in our landscapes. It could be used along a street under power lines and would not require pruning for many years. The tree is tough and adapts to restricted soil spaces. Pest resistance: resistant to pests/diseases Verticillium wilt susceptibility: susceptible Soil tolerances: clay sand loam acidic alkaline well-drained Trunk and Branches Trunk/bark/branches: branches droop showy typically multi-trunked thornsĬurrent year twig thickness: medium, thick Fruit characteristics: does not attract wildlife showy fruit/leaves not a litter problem
