noted that all these varieties have been hardy in
the past, but age was adding up and age evidently had somewhat to do
with their inability to take the punishment they got this past winter.
For all my large Bing and Lambert cherry trees were severely injured or
entirely winter killed, as were nearby peaches, apricots, pear, and some
apple trees, particularly in the larger sizes, while many of these
younger trees were uninjured, except that they are fruitless this
season.
Soft Shell Walnuts
(Juglans regia)
Broadview variety on Gellatly Farm, of 20 bearing trees, all suffered
winter injury for first time in 20 years. This injury varied all the way
from freezing back two to three feet of all higher branches and twigs,
to an actual loss of one-third to two-thirds of entire tree and trunk.
At date of writing all are staging a good comeback with no care but a
"wait-and-see" policy as to final treatment. There was so much loss as
to involve too much work if pruning and after care of sprouts were
undertaken. It was decided to leave the dead limbs and branches as a
protection to the fast growing new sprouts, which, without this
protection, would probably have been badly damaged by wind and rain
storms. Even large birds lighting on these new sprouts might break them
down.
The dead limbs will be gradually removed later, as the new limbs harden
up and take over. Many of these will be left as supports for at least
two years, when I expect most of these trees will be back in production,
if we get a return to normal (minus 10 deg. F.) winters, many will produce
in 1951, as the new wood is showing a good growth of catkins. Although
all bearing trees on my place were injured, the younger trees in my
nursery were not hurt to any noticeable extent. At Summerland
Experimental Station, 25 miles south of Gellatly, grow two large
Broadview walnut trees supplied by myself. I had grafted on these black
walnut roots (~J. nigra~) at the ground line, in every respect like my
own. These trees are carrying a good crop. One shows slight winter
injury, the other none at all. The official low for their location was
22 deg. below F. with nearby unofficials to 30 deg. below.
Their present location is at least 200 feet above lake level, and on
very well drained sandy loam. Mine are about 30 feet above the lake and
on somewhat heavier loam. I note that trees on my more gravelly soil
came through in the best shape at official-22 deg. F., unoff
