The earliest varieties of the Vine require about five months to ripen their fruit from the time of starting the Vines; but kinds like the Black Hamburgh are better allowed six months. Late varieties, like the Muscat of Alexandria, Gros Guillaume, and others mentioned in the list of late Grapes at the end, require nearly eight months, but the Alicante and Lady Downes can be ripened perfectly between the beginning of April and the end of October. Grape-growers have, therefore, only to calculate when they will need any given crops to be ripe, and start their Vineries accordingly. Before starting the Vines they should be washed and cleaned, and so should any portion of the Vinery inside; the border should also receive a good watering. As regards temperature a few noteworthy fruit-growers allow considerable latitude, preferring rather to be guided by circumstances and weather conditions, than by hard-and-fast F rules. With the Vine, however, in the earlier stages of forcing, unnaturally, not to say injuriously, high night temperatures have been the rule hitherto; but a great change has taken place of late years in favour of lower temperatures, as being both better for the Vines and more economical. If we compare the night temperatures generally recommended for the Vine, from the starting period till the setting of the fruit, it will be found that they far exceed the average night temperature during the same period of growth in those countries most favourable to the Vine; and what makes the matter worse, these excessively high temperatures are given under circumstances which only increase their power of mischief; as, for instance, when the Vine is forced in a Vinery under our cloudy skies, and during the long dark...
