Do not use too much stuff nor bundle too tightly.
Not Orange on the Osage.
Can the Navel orange be grafted on the osage orange? I understand it is
done in Florida, and would like to know if it has been tried in
California.
It cannot. It has not been done in Florida nor anywhere else. The osage
orange is not an orange at all. The tree is not a member of the citrus
family.
No Pollenizer for Navels.
I read that the flowers of the Navel orange are entirely lacking in
pollen, or only poorly supplied. If this is true, what variety of orange
would you plant in a Navel grove - to supply pollen at the proper time?
We would not plant any other orange near the Navel for the sake of
supplying it with pollen. Pollen is only needed to make seeds, and by
the same process to make the fruit set, and Navels do not make seeds,
except rarely, nor do they seem to need pollen to make the fruit set.
Water and Frost.
From how many acres could I keep off a freeze of oranges with 1000
gallons per minute? The water is at 65 degrees.
The amount of water will prevent frost over as large an area as you can
cover with the water, so as to thoroughly wet the surface, but the
presence of water will only be effective through about four degrees of
temperature and only for a short time. If, then, the temperature should
fall below 27 degrees and should remain at that point for an hour or
two, it is doubtful if the water would save your fruit.
