252 THE PEACH AKD NECTABINE. 



5it., 6ft., or '8ft, apart, according to their size, A single row or two 

 rows may also be arranged on the side borders. 



Bnsh trees'CFig, 59) are seldom nsed to furnish an entire honse, though 

 the form is well adapted for low houses. But bushes are more generally 

 eimployed to fringe the sides of walks or borders, and to fiU up the .lower 

 parts of houses where the taller standards or pyramids cannot be placed. 

 The great advantage of this mixed style of furnishing is that it enables 

 more fruit to be grown in a given area than by the use of any one style 

 Qf tree only. Perhaps the most profitable method of fumislung a 

 permanent orchard house is to use standards for the middle and chief 

 parts of the centre and side borders flanked aU the way routed with bush 

 trees or cordons. 



VI. — Routine Treatment. 



The soil already described for peaches in the open air is also the best for 

 trees inside. The borders should be composed of sound loam, and if poor 

 it may be enriched with an admixture of crushed bones. The great merit 

 of these as fertilisers is that they enrich for a long period, and do not 

 break down or injure the texture of the soil. The calcareous matter of 

 the bones is also most useful to the peach. The depth of borders for 

 peaches under glass should average 80in. or 3fti, its width the same as 

 the house. The trees under glass being deprived of natural dews 

 and rains, it is almost impossible to over-syringe peaches and nectarines 

 from February till the end of September. Two heavy sprinklings a day 

 tend to keep down aU insects as well as to strengthen and refresh the 

 trees. Of course, early in the season and during dull weather these heavy 

 shower baths will be dispensed with. 



Glass walls or cases often suffer severely and become a prey to red 

 spider and thrip for lack of attention to these shower baths twice a 

 day. 



The roots also need much more water under glass. Taking the annual 

 average rainfall at SOin., it requires a good many artificial waterings to 

 reach to that quantity ; and peach roots under glass are also, as a rule, 

 subjected to more severe drying conditions than those in the open air. 

 The sharp currents of air incident to thorough ventilation evaporate the 

 moisture rapidly out of the ground, and as the drainage of peach borders 

 under glass, whether outside or in, should be perfect, there is little 

 danger ,of over-watering them. In aU artificial waterings it is always 

 needful to bear in mind the great difference in quantity required for 

 outside peach house borders and those wholly inside. The latter, as a
