Transplanting Orange Trees.

Can you transplant trees two years old with safety to another location in same grove, same soil; etc.?

Yes; and you can move them a greater distance, if you like.  Take up the trees with a good ball of earth, transplanting in the spring when the ground has become well warmed, just about at the time when new growth begins to appear on the tree.  The top of the tree should he cut back somewhat and the leaves should be removed if they show a disposition to wilt.  You should also whitewash or otherwise protect the bark from sunburn if the foliage should be removed.

Protecting Young Citrus Trees.

Is it necessary to have young orange trees covered or leave them uncovered during the winter months?

It is desirable to cover with burlaps or bale with cornstalks, straw or some other coarse litter, all young trees which are being planted in untried places; and even where old trees are safe, young trees which go into the frost period with new growth of immature wood should be thus protected.  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.  Water is only of limited value in the prevention of frost, and of no value at all when the temperature falls too low.

What to Do with Frosted Oranges.

What is the best plan of treatment for frosted orange trees?  The crop will be a total loss.  It does not show any tendency to fall off the trees, however.  Should it be picked off, thrown on the ground and plowed under?  Should this be done right away or later?
