This is an article by John Garrity of SI's "Golf Plus" which reveals some of the money figures involved with tree transplantings at the University of Florida's course.
"Many trees will fall in the demolition phase of the Florida course renovation, but the best will be saved, and about 70 have been targeted for transplantation. "This is a good time to prune their roots because the sap is not flowing," says course superintendent Mark Birdsell, examining a 25-foot live oak between the 4th and 5th fairways. "Your tree nurseries are out right now root-pruning their trees for sale next year."
This particular tree, whose trunk is about 12 inches in diameter, is as symmetrical as a Rorschach inkblot, unlike the moss-draped heritage oaks that lean dramatically over various holes. That's because this tree came from a commercial nursery. "This is about a $3,000 tree if we purchased it today, and with installation it would cost about $4,400," Birdsell says. "But we can hire a man and a tree spade [to root-prune] for $1,000 a day."
The root-pruning itself is crude surgery. The tree-spade operator backs up his truck to the tree and encircles the trunk with the spade, a powerful machine with four knife blades angled to meet below the ground. When the operator throws the switch, the blades slice down through the surface roots and join under the tree to create a compact root ball. It only takes a few minutes, and the tree has weeks or months to develop new feeder roots before transplantation. "We'll do some canopy work, too, trim some branches," Birdsell says. "That's necessary to keep the tree healthy when you've cut away the roots."
There are significant savings to be gained by transplanting, which is why Weed's budget proposal calls for 15 days of tree-spade work at $1,200 a day for a two-man crew. "If we can move four eight-inch trees a day," says Scot Sherman of Weed Golf Course Design, "you're talking only $300 a tree." In addition, Weed plans to transplant 15 larger trees, in the 20- to 24-inch range, and spend between $75,000 and $100,000 for 100 new oaks and pines from a local nursery.
"There could be more," says Sherman. "If we save money on contracts, we'll put it right back in landscaping."
