One Thousand Questions in California Agriculture Answered
Wickson, Edward J. (Edward James)
Agriculture -- California
Where one is bringing along a young orchard, without irrigation, it is
doubtful whether it is not better policy to give the trees all the
advantage of clean cultivation and ample moisture than to undertake
intercropping. If you live on the place and wish to grow vegetables
between the rows, the thorough cultivation to bring the vegetables along
satisfactorily would help to preserve moisture enough both for the
vegetables and for the trees, but this is very different from growing a
field crop by ordinary methods of cultivation. Select a crop which will
require summer cultivation, like corn, potatoes, squashes, and beans,
and never a hay or grain crop which takes up moisture without working
the soil for the greater moisture conversation which hoed crops require.
In choice of hoed crops be governed by what you can use to advantage,
either for house or the feeding of animals, or what you can grow that is
salable with least loss of moisture in the soil. The choice is governed
entirely by local conditions, except that leguminous plants - peas,
beans, vetches, clovers, etc. - do take nitrogen from the atmosphere and
can thus be grown with least injury and sometimes with a positive
benefit to the fertility of the soil.
Regular Bearing of Fruit Trees.
How can trees be induced to bear regularly instead of bearing
excessively on alternate years?
The most rational view is that in order to bear regularly the tree must
be prevented from overbearing by thinning of the fruit; also that the
moisture and plant-food supply must be regularly maintained, so that the
tree may work along regularly and not stop bearing one year in order to
accumulate vigor for a following year's crop. There is some reason to
believe that some trees which seem to overbear every year can be
prolonged in their profitable life and made to produce a moderate amount
of fruit of large size and higher value by sharp thinning to prevent
overbearing at any time. This is found clearly practicable in the cases
of the apricot, peach, pear, apple, table grape, shipping plum, etc.,
because the added value of larger fruits is greater than the cost of
removing the surplus.
Scions from Young Trees.
I have bought some one-year-old apple trees that are certified pedigree
trees. Would it be practical to take the tops of these trees and graft
on one-year seedlings and get the same results as from the trees I
bought? Will they bear just as good, or is it necessary to take the
scions from old bearing trees?
They will bear exactly the same fruit as the young trees will, but you
cannot tell how good that will be until you get the fruit. The advantage
of scions from bearing trees is that you know exactly what you will get,
for, presumably, you have seen and approved it.
Late Pruning.
Will I do injury to my peach trees if I delay pruning until the last of
February, or until the sap begins to run and the buds to swell?
