Propagation. Cuttings may be taken at any time from December to March. They are rooted in pure silver sand or very sandy soil in a propagating frame, temperature 60° F. Cuttings are prepared from side growths on the flowering. Those mid-way up these stems are the best ones to take. They are simply pulled off with a heel attached and this is then trimmed up.
. Cuttings are potted singly in 3-in. as soon as they are rooted. Subsequently, they are potted on as necessary until by May or early June they reach the 6- or 7-in. pots, in which they will flower. At first use an ordinary such as JIP.For the later use JIP.Alternatively carnations may be grown in rings of soil on an aggregate base. Pot firmly.
Stopping, This is first done when thehas made seven joints. The top joint is broken off to encourage side growths to form.
The plants are stopped a second time when side growths resulting from the first stopping have made about eight joints. Two joints are broken out. Complete this second stopping by early July ifare required by Christmas.
Routine Cultivation, From October to May plants must have the protection of a, but during the summer they may be placed in a frame and ventilated freely. Stand the frame on bricks to give height and allow air to enter From below as well as above. Cool, airy treatment is necessary throughout. Even in winter, heat is used more to dry than to warm the atmosphere, but frost must be excluded. By taking over a long period plants may be had in flower most of the year. Water moderately in summer, sparingly in winter. Excessive heat encourages thrips and red spider.
