Aspen ( Populus tremuloides )

The quaking aspen looks best in forest or grove plantings where its Fall colors are multiplied.  Specimens being collected transplant best before they leaf out in the Spring, or after leaf drop in the Fall.  For the latter, be sure to protect the new roots from especially unexpected frost damage.  Trees in leaf have a lower chance of survival, but they can still be collected with some success.  Just expect those trees to drop many of their current leaves afterwards.  Trees growing near to one another will probably have the same horizontal root system, so prepare to collect several trees at once or cut the root at some point.  Controlled drought-stress brings about earlier Fall colors.  Some of the faults of these trees as bonsai which enthusiasts have mentioned: disease-prone, subject to insect infestations, short-lived, and can shed branches at random intervals.  Protecting aspen year-after-year from frost is said to prevent lower branch die-back.  Leaf-cutting is successful with aspen for getting a smaller second set of leaves.  Just be sure the petiole (leaf stem) remains on the tree.
