POT FRUIT CULTURE AND ITS ADVANTAGES 137 



the green color so much desired, especially early in the season of growth. Bon 

 Arbor will rectify this evil, used according to directions. A certain amount 

 of lime and potash is essential to all stone fruit, but as the make-up of different 

 soils varies considerably, it would not be advisable on my part to prescribe 

 any given quantity. It is enough for me to say that they are necessary and 

 should be applied in some form. If lime is needed, the best way to use it is 

 in the potting compost. Wood ashes may also be used in the same manner. 

 With a regular system of feeding, a large tree may be grown in a comparatively 

 small tub, with results in favor of this method. 



I have said that orchardhouse fruit delights in an abundance of fresh air; 

 but it should not be admitted in a haphazard way, especially during February and 

 March and at times far into April. If a cold, cutting wind is blowing from the 

 east, open the ventilators on the west side, if needed, or on the opposite side, 

 as the case may be. The main object in view is to avoid cold, cutting winds 

 while admitting air whenever the conditions call for it, and particularly so 

 when the trees are in bloom, as too much coddling at this stage endangers the 

 desired set. Keep a circulation of air (m whenever the thermometer registers 

 above 60°, and as the hot weather sets in, admit all the air possible, both top 

 and bottom, closing the bottom ventilators at night, but leaving the top ones 

 on, or just bringing them down enough to shed the rain in case of storm.
