avor, thin shelled, a
little small but with a better than usual percentage of kernel.
If heartnuts have a future, which seems almost inevitable, it looks as
though Canada, if it continues as it has started, will be one of the
main sources of supply for varieties. The Canadians are doing a creative
job.
_THE SOUTHERN AREA._ There are no nurserymen who report from the
southern area. Practically all are interested in the production of nuts,
but they are more alive than their northern neighbors to the value of
timber, and more of them count upon it for a part of their profit from
the planting of nut trees.
Interest is about equally divided between methods of propagation,
grafting, budding, top-working, planting seed of better varieties,
artificial cross-pollination, and searching their neighborhoods for wild
trees that show promise of superiority.
The species being planted experimentally or commercially are, in order
of precedence, black walnut, persimmon, pecan, Persian walnut, Chinese
chestnut, hickories, filberts, hazels, heartnuts, Jap chestnuts,
almonds, mulberry, native chestnuts, Jap walnuts, pawpaws and beech.
Species of wild trees found locally follow closely the pattern of
planting mentioned above, which is as it should be.
Climatic conditions are, in-general, favorable. Peaches are in most
places reliably hardy. Lowest temperatures normally expected range from
22 deg. above to 20 deg. below zero; and the highest normal summer temperatures
range from 90 deg. to 115 deg.. Dates of normal late spring frosts have a very
wide spread, being all the way from March 1 to May 12. Normal early
frost expectancy is from Oct. 10 to Nov. 15. All long-season crops
mature well. The chief climatic enemies are drought and hot, dry winds.
As to growth conditions, clay soils predominate, but with plenty of
loamy bottom land for nut planting. Acid soils predominate somewhat over
lime soils, growing more unfavorably alkaline in the south-west.
Cultural practices are generally the same as in the north, but with a
greater proportionate use of mowing and mulching, no doubt induced by
the need for protection against greater heat, as well as for
conservative of moisture. A greater proportionate failure of young trees
to start first year's growth is also probably due to heat injury in the
spring and summer following planting. Tree wrapping seems to be the
corrective chiefly indicated.
