How to Grow Lombardy Poplars Tree

Lombary Poplar trees are planted as cuttings using 8 to 10 segments of one-year old stems. This process is called vegetative propagation and is one way to ensure continuity of the genetic makeup of desired clones. Producing your own cuttings is great way to save money and ensure that you have quality stock year after year. It does, however, require a fair amount of manual labor and storage space.
Lombardy Poplar Tree cuttings do best if taken from healthy trees, especially if taken in the early morning. Use a sharp, thin-bladed knife or sharpened Pruning shears and remove all the leaves from the bottom half of a 6-inch stem. If the leaves on your cutting are large, cut them in half to reduce water loss during rooting. Place the cutting up to half its length in a medium made of half peat and half sand; water well and keep in a spot that receives indirect sunlight. Keep the soil moist but not saturated by occasionally misting the cutting. When it has rooted, transfer it into a larger container or into a separate bed with others as its chances of survival are improved if not immediately planted in its permanent location. Cuttings, also called whips, can be harvested in late fall and refrigerated until planting time. If using this method, be sure to soak the cutting for 24 hours before planting and keep the area weed-free during the first two years of growth as young Lombardy Poplar Trees are easily overtaken by other vegetation.
