Urban Landscaping- Part I: Bareroot Trees
June
18, 2009
1:00-
2:00pm EST
A best management practice that is increasingly
moving from research to the field is bare root planting. Whether from a
nursery field to the city street or just from one place in your yard to
another, it's the roots that suffer when trees are transplanted. Shade
tree roots are found primarily in the top 12 inches of soil, and extend
horizontally up to and beyond the dripline. An
unbelievable 90% of tree roots are routinely left behind in the nursery
at the time of harvest. In an industry where having a viable root
system is the primary determining factor of whether trees survive and
thrive in their new location, current practices must be reevaluated.

RESEARCH PERSPECTIVE
Nina
Bassuk, Urban Horticulture Institute at Cornell University (Ithaca, NY)
Research by Nina Bassuk indicates that many tree species fare better
when transplanted bare root as opposed to balled and burlapped
(B&B) or containerized (grown in pots). When properly handled,
the bare root method is less traumatic for the trees' roots, and can
lessen transplant shock and recovery time. Bare root stock offers many
benefits including up to 200% more root mass than B&B or
container trees.

ON THE GROUND
Patrice Sheehan, Delaware Center
for Horticulture (Wilmington, DE)
Last year, the
Delaware Center for Horticulture started using bare root stock in their
plantings, and have found that bare root stock makes for easier
plantings. However, working with bare root stock requires careful coordination.
Once they leave the nursery, bare root trees need to get in the ground
within a week at the longest. With no soil, the roots can dry out and
die if left exposed for any time.
