Weekends are quieter than weekdays in Manhattan’s financial district –
so that’s the best time for moving
a tree through the crowded city streets. Trane Construction Company at 55 Water
St. needed to make some renovations to their site which would displace two
large Callery Pear trees. A new location was chosen at a public school on the
island side of the Manhattan Bridge.
Early Saturday morning: pruning to reduce the
canopy size and improve the overall
Work began on Friday night when a crew came in to break up and remove the sidewalk cement surrounding the trees. The City of New York would allow for the closure of the sidewalk only until 7 p.m. on Saturday, so the pressure was on!
Our Almstead crew began early the next morning, painstakingly digging a trench around the base of the tree, excavating 5 feet down to get as much of the root structure as we could. We knew what the size of the new sidewalk planting pit would be, and pruned the roots to form a root ball as large as possible. City trees rarely have the luxury of developing an extensive root system; they struggle to survive under adverse conditions. Our job was to give these trees the best start possible in their new location.
We also pruned the trees so the canopies would be smaller – making less work for the smaller root structure. We wrapped the root balls in burlap and tied them to keep them intact. We also gently tied the canopy together to prevent damage on the journey.
Digging out a tree. Because of the existing
curb 2’ from the trunk, we elongated the root ball
to retain as much root mass as possible.
We placed them in their new holes and filled in the remaining space with high end compost, specialized soil, organic biostimulants and additives to increase water retention in the soil and promote healing and rooting. Finally we covered them with a 4” layer of hardwood mulch to further protect them from temperature fluctuations and inhibit moisture evaporation from the soil.
We’ll be stopping by every 2 to 3 days to make sure the trees are well watered and not showing any ill effects from their journey. We have designed an ongoing Plant Health Care program for the next two years to give these pear trees the best start possible in their new home. We hope to see them thrive in front of the school.
