Winter and Summer. Winter Greens include most of the members of the cabbage tribe which are planted out in June and July to stand for part or the whole of the winter. The exceptions are found in Celery Cabbage, Couve Tronchuda, and Kohl Rabi, the leaf portion of which is used during the summer and autumn. Summer Greens consist largely of Spring Cabbages, which are planted in August in firm ground. The vegetables Spinach Beet, Perpetual Spinach, etc., though giving greenstuff both in summer and winter, do not come within the term summer and winter greens. It may be pointed out that greens are not nearly so necessary in summer as in winter, owing to the abundance of other crops from May to October, though many of us would be sorry to be without the sweet white cabbages so freely cut in June and July. . Cauhflowers, though often termed Winter Greens, do not come within the strict meaning of the term, owing to the fact that the heads find different purposes in the home to Broccoli, Brussels Sprouts, Cabbages, Kale, and so on. The term winter green used to be limited to Broccoli, Curled Greens, and Kale, but of late it has come, as we have already mentioned, to include all the members of the great Cabbage or Brassica Family with the exceptions named. Culture of Greens.Full details of growing greens will be found under Borecole for Curled Greens and Kale, and under the separate articles on the vegetables named above. Two points of special importance may be mentioned, however ; first, that planting of all kinds of greens in drills is strongly advised for the dual purpose of conserving moisture and enabling more thorough earthing up ; and secondly, that all greens whether for the summer or winter should be planted in firm ground, each individual plant being made very firm. This will mean the plants will stand through the winter much better, and will not grow long and leggy in the summer. Winter Greens should never be fed with nitrogenous fertilisers after the 1st of August. Summer Greens can have weak liquid manure given them throughout the summer and will in return be of greatly improved quality. Clubroot.All greens are very liable to clubroot disease, and if the land is badly infected many thousands of plants will fail. The attention of all readers is drawn to the article on Diseases of Plants by a well-known expert, and if the suggestions contained in it under Clubroot are carefully followed, this disease, otherwise a serious menace, will be kept well in control, and in all probability completely cured. Pests.Greens are very liable to attacks of the Cabbage Root Fly and Maggot as well as other pests. The reader should turn to our experts article on Insect Pests for the methods of control.E. T. E.
