Gardeners often dispense with the pot, using sphagnum moss and leaf-mould only when propagating indiarubber plants, perpetual carnations, dracaenas, &c.
Carnations, Marguerite: half-hardy, 9 to 12 in., colours various.
Give auriculas and carnations abundance of air, but keep the roots rather dry to prevent damping off.
Layer carnations and pipe pinks in the end of the month.
Saprophytic bacteria can readily make their way down the dead hypha of an invading fungus, or into the punctures made by insects, and Aphides have been credited with the bacterial infection of carnations, though more recent researches by Woods go to show the correctness of his conclusion that Aphides alone are responsible for the carnation disease.

Woods, Stigmonose, a Disease of Carnations, Vegetable, Physiol.
Zonal pelargoniums, fuchsias, shrubby calceolarias, dahlias, carnations, &c., to retain on the cutting some of its leaves, so as to supply the requisite food for storage in the callus.
One whole summer, sometimes two, must elapse before the layers will be fully rooted in the case of woody plants; but such plants as carnations and picotees, which are usually propagated in this way, in favourable seasons take only a few weeks to root, as they are layered towards the end of the blooming season in July, and are taken off and planted separately early in the autumn.
Increase roses and American shrubs, by layering, budding or cuttings, and go on with the layering of carnations and picotees.
Propagate all sorts of herbaceous plants by rooted slips or suckers; take off layers of carnations, picotees and pansies.
Continue the propagation of herbaceous plants, taking off the layers of carnations, picotees, pansies and chrysanthemums, by the end of the month; choice carnations and picotees may be potted and wintered in cold frames if the season is wet and ungenial.
Plant Houses, Frames, &c. - Carnations and picotees in pots must be kept rather dry to prevent damping off.
Carnations and other plants that are throwing up flower stems, if wanted to flower in winter, should be cut back, that is, the flower stems should be cut off to say 5 in.
Roses, carnations, camellias, azaleas, pelargoniums and the hardier sorts of plants will do better if placed in a cold frame or pit until the middle of November than they would in an ordinary greenhouse.
