[CANUFNET] tree planting along flood plains

[via CANUFNET]

Silver maple, bur oak, cottonwood, red osier dogwood, nannyberry, native 
willows will do best on urban floodplains.

You have to assume compacted soils, buried concrete in places, occasional 
flooding and construction going on around them from time to time, and the 
soils are probably urban fill (disturbed with no natural soil profile and 
maybe the calcareous C horizon on top). Wet in spring, rock hard clay in 
summer.

Avoid pin oak and red maple. They get chlorosis from the alkaline soils. 
Will never be healthy.

Avoid highbush cranberry.  All the nurseries in Ontario sell the invasive 
European Guelder rose by mistake and don't even know the difference.

Make sure you get real cottonwood, most nurseries sell Carolina poplars. 
Balsam poplar would do if you can't get cottonwood.

Hello,

John,

Birch (Betula), Alder (Alnus), Cottonwood (Populus) and Willow (Salix) would 
be some
of my favorite choices for floodplains. Red Maple (Acer rubrum) too 
apparently does well;
as it is commonly called a “swamp maple.”

Here is a booklet from the USDA with some good, clear diagrams.

Best,
