[CANUFNET] Planting depth

[Mark Peterson]

The problem with planting at the same depth as previously planted is that often the previous depth may not be the 'proper' depth. In the nursery, the 'proper' depth (in my opinion should be at the point of root flare) may have been buried due to cultivation practices. Sometimes this depth may be 4 inches or more. Look at natural growth trees - they all have the root flare visible. Find the root flare.

Tree Visual Impact
Can we afford to wait 50 to 100 years for a street tree to mature to gain the right scale and visual effect? Will a tree planted today be alive in 50 years? The visual impact of a street tree lies in crown volume. A tree must be large enough to give immediate shade and should be in sufficient numbers to create visual continuity. Therefore, plant either a few large trees or many smaller ones.

  Hello everyone,

   

  I have recently attended to two seminars, one with Dr. Ed Gilman and one with Dr. Hanna Mathers.  The two have very different views on planting depth.

  I would like to hear others opinions on planting trees at the same depth as previously planted vs. planting higher (at or near the root flare).  It seems there may be possible problems associated with either practice when planting container or bareroot trees and some issues may be species specific.  We have had good results with planting depth near the root flare and have not experienced any issues because of it.  I am interested in your comments.
