One Thousand Questions in California Agriculture Answered

by Edward J. Wickson

I have some orange and lemon trees which were sent me with their roots balled up with dirt and sacks. As we are still having frosts I have not wanted to set them out. Would it not be better to let them stay as they are and keep the sacks wet (they have a sack box over them) than to put them out while the frosts last?

Your citrus trees will not be injured for a time unless mold should set in from the wet sacks. Get them into the ground as soon as the soil comes into good condition, and cover the top for a time after they are planted to protect them against frosts. This would be better than to hold them too long in the balls, but do not plant in cold, wet soil; hold them longer as they are.

The Navel Not Thornless.

I have lately purchased some Washington navel orange trees, and upon arrival I find they have thorns upon them. I thought the Washington navels were thornless.

The navel orange tree is not thornless. It is described as a medium thorny variety, so that the finding of thorns upon the trees would not be in itself sufficient indication that they were not of the right variety.

Over-size Oranges.

I have some orange trees in a disintegrated granite with a good many small pieces of rock still remaining in the soil. What I wish to know is whether it is probably something in the soil that makes them grow too large, or is it probably the method of treatment? What treatment should be adopted to guard against this excessive growth?

Young trees have a natural disposition to produce outside sizes of fruit, and this is sometimes aggravated by excessive use of fertilizers, sometimes by over-irrigation. We would cease to fertilize for a time and to regulate irrigation so that the trees will have enough to be thrifty without undertaking excessive growth. Such soil as you describe is sometimes very rich at the beginning in available plant food, and fertilization should be delayed until this excess has been appropriated by the tree.

Budding or Grafting in Orange Orchard.

I have land now ready to be planted to oranges, but it is impossible for me to buy the necessary budded stock now or even later this year. Would you advise me to plant the "sour stock" as it comes from the nursery and have it budded or crown-budded later? Are there any real objections to this method, and, if so, what are they?
