Managing Sucker Growth on Contorted Filbert

Gardeners, on occasion, may find plants growing in the garden that aren't the ones
that they planted.
In many cases that's because the cultivar they bought has died, failed for whatever
reason
and the plant continues to grow from the root stock.
This is true many times with hybrid Tea Roses. This is true for
virtually all of our crab apples
and
just about all of our shade trees as well.
These are propagated asexually,
meaning the root that supports the tree has no,
it has genetic familiarity with the plant that's on top,
but it may have a different structure, may have a different bark color, and oftentimes
it has a different bloom.
So when you find these things, they're usually suckers coming from the soil line
where you would reach in, prune those suckers off just below the soil line to maintain the
cultivar you're interested in.
In the case of this Contorted Filbert, or Harry Lauder's Walking Stick as its common
name,
it has grafted onto a common Filbert.
The common Filbert is coming from the root stock in this case,
and the growth comes straight up.
The fact that the Harry Lauder's Stick is slow growing
the standard
hazelnut here will, in very short order,
grow through the canopy of this taking over the plant and we would lose this cultivar.
Appropriately, we would reach inside, reach down to the soil line, find out where these suckers
are coming from, cut into the soil line hopefully
getting it cut below ground
eliminating the re-sprouting.
And when you're all done
you maintain the cultivar
that you've been hoping for and purchased.
