The Garden Under Glass

126 THE GARDEN UNDER GLASS servatory or for cutting are obtained. For winter and spring flowering sow in August and October. Nicotiana.—Some like to grow the hybrid forms of these plants in pots. They are not difficult to grow, being sown early in February, pricked off early and potted up from boxes to 3-inch pots, being moved later to flower in the 7-inch size. Cool conditions are required for these as for practically all the outdoor plants named. Pentstemons.-—These are not often grown in pots, except by nurserymen for exhibition, but given a good bold variety they make a striking display. Strike cuttings in a cold frame in the autumn, pot up in 3-inch pots in the spring and move on to 6-inch. This method of culture also provides good plants for the beds. Petunias.-—These were at one time recognised as greenhouse plants, but of late they have lost favour both in greenhouse and garden. There is no reason why they should not again grow into favour, as I think they will when some of their newer rivals have become stale. They can be propagated from seeds or cuttings in the spring and grown along in the same manner as plants for bedding. Stocks.—Stocks of the intermediate section are now so largely used for the greenhouse that they may almost be classed as greenhouse plants. Seeds should be sown from June to August and be pricked off three in a pot to be eventually worked on to 6-inch or 7-inch pots. When about three inches high pinch the points out and take up about three growths per plant. June sowings will usually give Stocks at Christmas, with a succession from those sown in August, but during a mild autumn, such as that of 1913, they cannot be prevented from flowering much earlier. Ten weeks’ Stocks may be grown for the purpose, but most firms now catalogue a selection of winter-flowering
