This past week I had occasion to pass the same suburban Massachusetts middle school on two days in a row, and on each of those days my eyes goggled at the sight of a new planting on a slope facing the road.  The array of brown, grey, and coppery-red foliage — on the trees that [...]

I took a great class this past January at the Arnold Arboretum.  It was called Grafting Techniques for Ornamental Trees, and was taught by Jack Alexander, the Arboretum’s Plant Propagator.  Jack, who is not only an extremely talented plantsman but an excellent teacher, taught us how to prepare cuttings, how to make several different kinds [...]

If we can clone crabapples, maples, and chamaecyparis, why can’t we clone the enormous redwoods that stand as the world’s tallest trees?  Well, apparently we can. This article in Sunday’s New York Times (4/10/2011) explains how a group of arborists dedicated to propagating and planting clonal stands of coastal and giant sequoias, using tissue and cuttings [...]

Yesterday I swung by the site where Herbie, the American Elm in Yarmouth, Maine, had stood for over two centuries.  Herbie was taken down last January; to read the tale see this post, and to see photos of Herbie’s stump, click on this link. I hadn’t planned to stop and see the stump — what [...]

Well, it wasn’t there. [...]

A reader, Mark Vanderwouw from Shady Lane Expert Tree Care, Inc. wrote a comment on the post titled Another Air-Tool Bare-Root Transplanting (cross-posted from TakingPlace.net, the other blog I co-write for landscape architects).  His company is excavating out several large specimen trees for a one-year storage period, after which they will plant the trees in [...]

At New England Grows, I met Jim Doyle, one of Wellesley College‘s team of arborists. He told me about an air-tool transplant that he and a colleague performed last November at the College.  He was kind enough to send photos, and with them included this text, which I have edited only slightly: “My colleague Don [...]

Another question asked at last week’s New England Grows about bare-root transplanting was “How do you make sure the roots don’t dry out?” The answer, of course, is that you water the tree you’re moving.  You water it thoroughly a couple of days before the transplant, to insure that the tree’s tissues have good turgor pressure [...]

Thousands of people showed up at New England Grows this past week.  One of the conference’s principal speakers, Bonnie Lee Appleton, unfortunately fell ill and had to cancel her Wednesday talk; for a while the day before the conference it looked as if one of the two convention center ballrooms would be empty for a [...]
