Fruit Growing 63 



No PoUenizer for Navels. 



/ read that the Hozvers of the Navel orange are entirely lacking in 

 pollen, or only poorly supplied. If this is true, tvhat variety of orange 

 would you plant in a Navel grove to supply pollen at the proper titne? 



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 hozv many acres could I keep off a freeze of oranges zvith 

 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 tem- 

 perature 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 shoiv any tendency to fall off the 

 trees, however. Should it be picked off, thrown on the ground and plozved 

 under? Should this be done right away or later? 



Unsound fruit should be removed as soon as its injury can be 

 conveniently detected and worked into the soil by cultivation; never, 

 however, being allowed to collect in masses, which is productive of 

 decay and which may be injurious to roots. If trees are injured 

 sufficiently to lose most of their leaves, the fruit should also be re- 

 moved if it shows a disposition to hang on. This will be a contri- 

 bution to the strength of the tree and its ability to clothe itself with 

 new foliage. 



Pruning Frosted Citrus Trees. 



How shall I prune two-year-old orange orchard, also nursery stock 

 buds that are badly injured by frost; how much to prune and at what time? 



As soon as you can see how far injury has gone down the branch 

 or stem, cut below it, so that a new shoot may push out from sound 

 wood, and heal the cut as soon as possible. This applies to growths 

 of all ages. In the case of buds, if you can only save a single node 

 you may get a bud started there and make a tree of that. In the 

 case of trees, large or small, it is always desirable to cut above the 

 forkings of the main branches, if possible, and when this much of 

 the tree remains sound, a new tree can be formed very quickly. If 

 the main stem is injured, bark cracked, etc., cut below the ground
