[CANUFNET] [?? Probable Spam] Re: Planting depth

I have personally planted or supervised the planting thousands of trees.
When you use wire baskets beware of "nursery disease" that is the extra soil
on top of the root ball that results from mechanical cultivation in nursery
rows. Not only do you get less than 10% of the root fibre here but on top of
that you get an unnatural root ball. Having said this you need to peel back
the top layer of burlap at the least anyways to see. Yes, better to plant
slightly higher than grade especially on clay soils.

I agree with the majority of writers. Planting too deeply here on the west
coast is problematic. I have been teaching students to  plant trees at a
depth that exposes the top most root as per Gilman's work.

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.
