can get irrigation. Presumably your rainfall is too small for fruit
unless you strike underflow below the hardpan.



Cleaning Fruit Trays.



What do you advise for killing and removing the whitish mold that forms
on trays used for drying prunes? Would sunning the trays be effective,
or washing in hot water, or is there some suitable fungicide?

Good hot sun and dry wind will kill the mold. The spores of such a
common mold are waiting everywhere, so that your fruit would mold anyway
if conditions were right. Still, scalding the trays for cleanliness and
a short trip through the sulphur box for fungus-killing is commended.



Killing Moss on Old Trees.



I have some Bartlett pear trees that are covered with moss and mold, and
the bark is rough and checked. I have used potash (98%), 1 pound to 6
gallons spray. It kills the long moss, but the green mold it does not
seem to affect. The trees have been sprayed about one week. Some trees
have been sprayed with a 1 pound to 10 gallons solution by mistake.
Shall I spray these again with full strength, and when?
