The species is dioecious – male and female flowers are on different plants – with flowers in catkins and pollination achieved by the wind. The black poplar grows in low-lying areas of moist ground. Like most other pioneer species, the tree is characterised by rapid growth and are able to quickly colonise open areas.
If using in as hedge: All species in a wildlife hedge can be cut back or “Coppiced” without harm. In the 1st year after establishment the hedge can be cut back to stimulate growth of the hedge from the base thereafter cut every 2-3 years. If the weather is unsuitable for planting or receiving the hedging, dig a hole and bury the roots of the bunched plants, they can be held like that till planting. After planting it is advantageous to mulch the hedge with lawn mowing or leaf mould to suppress weeds and also be done with plastic or carpet cuts and covered with soil.
