One Thousand Questions in California Agriculture Answered
Wickson, Edward J. (Edward James)
Agriculture -- California
Grape vines are most successfully planted after the heavy rains and low
temperatures are over and before the growth starts: This will usually be
whenever the soil is in good condition, during the months of February
and March.
Covering Tree Wounds.
What is the best stuff to use on wounds and large cuts on my fruit
trees? I have used grafting wax, but it is expensive and not altogether
satisfactory.
Amputation wounds on trees can be more successfully treated with lead
and oil paint than with grafting wax. Mixed paint containing benzine
would not be so good as pure lead and oil mixed for the purpose and then
carefully applied as to amount so as not to run. "Asphaltum Grade D" may
also be used in the same way.
Covering Sunburned Bark.
Would asphaltum do to use an sunburned bark?
Owing to the attraction of the heat by the black color, asphaltum would
increase the injury by absorption of more heat. Some white coating is
altogether best for sunburn injuries, because it will reflect and not
absorb heat, and a durable whitewash applied as may be needed to keep
the white covering intact is undoubtedly the best treatment. Where the
bark has been actually removed, white paint would be superior to
whitewash to keep the wood from checking while the wound was being
covered laterally by the growth of new bark.
Too Much Pruning.
Same peach trees entering the third year were pruned early in the winter
very severely. The pruner merely left the trunk and the three or four
main laterals, the latter about one foot in length. A large proportion
of these trees have not sprouted as yet, though alder and better pruned
trees are all sprouted in the same vicinity. The bark is green and has
considerable sap. Will the trees commence to grow?
The trees will sprout later, after they have developed latent buds into
active form. The pruning probably removed all the buds of recent growth.
After starting they will make irregular growth, starting too many shoots
in the wrong places, etc., and considerable effort will be necessary to
get well-shaped trees by selection of shoots in the right places and
thinning out those which are not desirable.
For Broken Roots.
When the root of an orange or other fruit tree is exposed or brakes by
the cultivator, what is the best way to treat that root?
Where a root is actually broken it is best to cut it off cleanly above
the break. This will induce quick healing over and the sending out of
other roots. Where there is only a bruise on one side, all the frayed
edges of the wound should be cleanly cut back to sound bark, which will
have a tendency to promote healing and prevent decay.
Pruning in Frosty Places.
This appears to be a frosty section. Pruners are at work continuously
from the time the apricots are harvested until spring arrives. From what
is said in "California Fruits?" I judge late winter pruning would be
best far apricots and peaches. Am I correct?
