The numbers listed below are the heights of the majority of the branches
during a single season of growth from a 2 yr old stool. In March the plants
were all coppiced to the ground, so that what you see below is the amount
of growth from in just a few months. So S. alba 'Britzensis' started from
ground level in March and grew to 5.5' by July 13, eventually to reach
9' by October 8!
These willows are growing in Grand Forks, British Columbia, Canada, Zone
5. It is important to note that they are grown with irrigation (very necessary
in our climate), in good soil, no fertilizer and with weed-suppressing
cloth. Some of these willows may grow faster in your climate, and some
might grow slower. All measurements are approximate.
This information is particularly helpful if you are growing willows for
screening purposes.
One of our customers
observed that half of her S. koriyanagi 'Rubikins',
which was coppiced very early in the season, was much
taller than the other half, which she coppiced a few
weeks later. Both cuttings were done while the plant
was dormant. So we therefore suggest that for early
and maximum height, the plants be coppiced as early
as it is practical to do so. |
