AN EPITOME OF VINE CULTURE 159 there is always a danger of their snapping with forcible syringing. Syringing and Damping From the time of starting the vine until flowering, syringing and damping of the border and walk with a rosed can should take place twice daily and the vines should be syringed from both sides and along their whole length. The ventilators should be closed shortly after two in the afternoon. A temperature of 450 to 50° at night, with a slight rise in the daytime, will be sufficient heat for some time. Sudden fluctuations of temperature must be sedulously avoided. Stopping the Growths When the young shoots of the vine have been tied down the question of stopping will arise. Each growth should be stopped at the second leaf beyond the bunch, and the laterals and sub-laterals which afterwards arise will need to be pinched back to their first leaf. The leading growth on the vine might with advantage be left to grow un-disturbed. This will tend to stimulate root action. Until the vines flower the damping and syringing should be done twice daily except on dull, cold days, when a light damping only will be needed. From the time the vines start to flower all syringing should be stopped, and except in the case of a severe attack of red-spider, no further syringing will be necessary throughout the season. To ensure free setting of the flowers a drier atmosphere must be aimed at by damping only once a day, and that at noon, by leaving a chink of air on the top ventilator all night, and by the use of a little more fire-heat during dull days. As a further means of ensuring success it is well to go over the
