[CANUFNET] Planting depth

I am with Gilman on this one. Too deep almost always causes problems, a little shallow, hardly any. That is coming back anecdotally here too.

Thanks.  In my view Gilman is correct.  In the last several years we have been removing lots of excess soil from the root ball and haven’t seen any issues with root crown injury.

Dr. Hannah Mathers stated at the SNLA conference that the root shank (area of exposed root tissue that results from production practices) should never be exposed above the soil line because it may be the cause of increased crown injury. She explained that it may not be cold hardy, may be prone to sunscald or easily injured by herbicides. I have not seen any increase of injury to this exposed root crown area and can not justify changing our planting practices when I have seen the issues of planting too deep.

I'm familiar with the Gilman work, what is the other view you mentioned?

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.
