DISEASES OF VINES 91 



wire (painted three coats of good whitelead paint 

 beforehand) stapled on to stout posts set well into 

 the ground at intervals close enough to admit of the 

 wires being strained sufficiently tight to give stability 

 to the trellis. When the vines are planted, lay on a 

 surface dressing of short manure to the thickness of 

 three inches between the rows and the vines in the 

 rows. The top wire should be about four feet from 

 the ground, the others being fixed one foot apart. The 

 canes should be treated as advised for vines under glass 

 in the way of disbudding, stopping and pruning, the 

 rods being, say, four and a half feet long, instead of 

 four times that length. 



DISEASES TO WHICH VINES ARE SUBJECT 



Of these, Mildew (OidiumTuckerij is the most common, 

 as well as the most troublesome, in cool vineries. Dry- 

 ness at the roots will produce mildew on the leaves of 

 trees and plants susceptible to its attacks in dry, hot 

 summers, out of doors as well as under glass, but the 

 appearance of mildew on young growths of vines and 

 peaches is generally caused by a low and too moist 

 atmosphere, that is, by a spell of cold, dull, showery 

 weather during the growing season. The only remedy 

 for vines and other plants attacked by this parasite or 

 fungus out of doors and in cool houses is to dust the 

 affected leaves while damp with flowers of sulphur, and, 

 weather permitting, to ventilate freely and endeavour to 

 keep the atmosphere of the house quite dry until the 

 grey powdery spots and blotches on the leaves and 

 berries have turned brown. Where vineries are heated 

 with hot-water pipes, the getting rid of the mildew pest is 

 a very simple and easy matter. A few handfuls of flowers 

 of sulphur should be stirred into a vessel containing lime- 

 wash, and applied to the heated pipes with a brush
