PEACH AND NECTARINE TREES. 247 



respect until they come to a bearing condition 

 as directed for trees against open walls. 



In order to bring the trees to a mature 

 state for bearing as soon sis possible, they 

 must be assisted with a little fire heat in 

 spring for the first two or three years. — 

 About the last week in February, let the 

 sashes be placed over the house, and the 

 trees be then headed down, about a fortnight 

 afterwards a little fire must be given so as 

 to raise the thermometer at night to 50 

 degrees, and in the day time as much air 

 must be admitted as will keep the house at 

 the same temperature. When the shoots 

 push, let the heat be raised in the night to 

 55, and by sun heat to 62 degrees; as the 

 season advances, more air may be given, 

 and the fire heat be discontinued at the end 

 of April, also when no danger from frost is ap- 

 prehended, all the air that can be given must 

 be afforded to the trees both day and night. 



If trees are obtained that have been 

 trained as described for three or four years, 

 and are in a bearing condition, let them be 

 taken up, replanted, mulched, watered at 

 the tops and roots, agreeably to the instruc- 

 tions given in each Chapter respectively. 

 A little fire heat must be given at the first 

 spring, regulating it as directed for the maiden 

 trees. As soon as the sashes are placed over 

 the trees, they must be pruned and the wood 

 must be cut a little shorter than is directed
