One Thousand Questions in California Agriculture Answered

It will not do any particular harm to let your peach pruning go until
the buds swell or even after the leaves appear. Late pruning is not
injurious, but rather more inconvenient.
Avoiding Crotches in Fruit Trees.
How can I avoid bad crotches in fruit trees?
Crotches, which means branches of equal or nearly equal size, emerging
from a point at a very acute angle, should be prevented by cutting out
one or both of them. The branching of a lateral at a larger angle does
not form a crotch and it usually buttresses itself well on the larger
branch. That is a desirable form of branching. Short distances between
such branchings is desirable, because it makes a stronger and more
permanently upright limb, capable of sustaining much weight of foliage
and fruit. Build up the young tree by shortening in as it grows, so as
to get such a strong framework.
Crotch-Splitting of Fruit Trees.
I have a young fig tree that is splitting at the crotches. I fear that
when the foliage appears, with the force of the winds the limbs will
split down entirely.
Perhaps you have been forcing the trees too much with water and thus
secured too much foliage and weak wood. Whenever a tree is doing that,
the limbs ought to be supported with bale rope tied to opposite limbs
through the head, or otherwise held up, to prevent splitting. If
splitting has actually occurred, the weaker limb should be cut away and
the other staked if necessary until it gets strength and stiffens. If
the limbs are rather large they can be drawn up and a 3/16 inch carriage
bolt put through to hold both in place; but this is a poor way to make a
strong tree. We should cut out all splits and do the best we could to
make a tree out of what is left. Then do not make them grow so fast.
Strengthening Fruit Trees.
I have read that some trees are propped by natural braces; that is, by
inter-twining two opposite branches while the tree is young, so that in
time they grow together. What is your idea regarding the practicability
of such an idea in a large commercial orchard?
Twining branches for the purpose indicated is frequently commended, but
it seems best for the use of ingenious people with plenty of time and
not many trees. To prune trees to carry their fruit so far as one can
foresee, and to use props or other supports when a tree manifests need
of a particular help which was not foreseen is the most rational way to
handle the proposition on a large commercial scale.
Time for Pruning.
What is the proper time for pruning pear and apricot trees?
Ordinary deciduous fruit trees can be successfully pruned from the time
the leaves begin to turn yellow and fall, until the new foliage is
appearing in the late winter or spring.
Grape Planting.
What is the proper time for planting grape vines?
