PART I. FRUIT GROWING 



Depth of Soil for Fruit. 



Would four feet of good loose soil be enough for lemons? 



Four feet of good soil, providing the underlying strata are not 

 charged with alkali, would give you a good growth of lemon trees if 

 moisture was regularly present in about the right quantity, neither too 

 much nor too little, and the temperature conditions were favorable to the 

 success of this tree, which will not stand as much frost as the orange. 



Temperatures for Citrus Fruits. 



What is the lozvcst temperature at which grapefruit and lemons ivill 

 succeed? 



The grapefruit tree is about as hardy as the orange; the lemon is 

 much more tender. The fruit of citrus trees will be injured by tem- 

 perature at the ordinary freezing point if continued for some little time, 

 and the tree itself is likely to be injured by a temperature of 25 or 27" 

 if continued for a few hours. The matter of duration of a low tempera- 

 ture is perhaps quite as important as the degree which is actually reached 

 by the thermometer. The condition of the tree as to being dormant or 

 active also affects injury by freezing temperatures. Under certain con- 

 ditions an orange tree may survive a temperature of 15° Fahrenheit. 



Roots for Fruit Trees. 



7 zvish to bud from certain trees that nurseries probably do not carry, 

 as they came from a seedling. Is there more than one variety of niyrob- 

 alan used, and if so, is one as good as another? If I take sprouts that 

 come up zvhere the roots have been cut, will they make good trees? I 

 have tried a few, nozu three years old, and the trees are doing nicely so 

 far, but the roots sprout up zvhere cut. I am informed that if_ I can 

 raise them from slips they will not sprout up from the root. Will apri- 

 cots and peaches grafted or budded on myrobalan produce fruit as large 

 as they will if grafted on their own stock? 



Experience seems to be clear that from sprouts you will get sprouts. 

 We prefer rooted cuttings to sprouts, but even these are abandoned for 

 seedling roots of the common deciduous fruits and of citrus fruits also. 

 The apricot does well enough on the myrobalan if the soil needs that 

 root; they are usually larger on the peach root or on apricot seedlings. 

 The peach is no longer worked on the myrobalan in this State. One 

 seedling of the cherry plum is about as good a myrobalan as another.
