compost of loam, leaf-mould, and sand, in equal parts. 
Should, however, no Poplar roots be near the surface 
in the required position, a portion of the soil there 
must be removed until they are exposed, and the 
compost added and well intermingled among the 
roots before planting. After the plant is put in

good watering being given last of all. Every spring 
top-dress with leaf-mould and sand.
