Healthy Vigorous Roots
The process of
undercutting the seedling taproot has been
standard practise in forestry nurseries for
many years. Appletons have trialed and successfully
implemented the use of undercutting of all
tree species grown in our nursery. As the programme
has expanded and been refined, we have built
and modified equipment specifically for undercutting.
With careful evaluation,
we have an understanding of how timing, blade,
depth and frequency of undercutting all interact.
The benefits of
the programme are numerous. Timely cutting
of the dominant tap root between five to 10
centimeters causes the root system to branch
and develop a well structured lateral root
system. This is particularly important with
species such as Quercus coccinea, which tend
to naturally develop a hockey stick/bent root
Many customers have
found that the undercut root system conforms
better to their container potting programme.
The more compact, fibrous root system closely
resembles that of a traditional two-year-old
1/1 transplanted plant.
With the advantages
of much greater root biomass in proportion
to above ground growth, greater survival and
stronger subsequent growth occurs in following
annually apply mycorrhizae inoculated pine
bark to our seedbeds to produce an enriched
high organic soil, which promotes a fibrous,
wellbranched root system.
