THE POT CULTURE OF CHRYSAN- 

 THEMUMS. 



E. H. Jones, MacDonald College, Que. 



Those who have tried know that 

 'mum growing is a delicate operation. 

 When successfully carried out, It more 

 than repays the outlay ot thought, 

 time and trouble. It seems to me that 

 there has been a lack of interest 

 taken in this beautiful flower the last 

 few years, and the sooner we, as 

 florists, awaken a little more interest, 

 and educate the general public, the 

 better it will be for the profession. 

 These flowers come at a time when 

 others are past, and I know ot none 

 so beautiful. Within the last 20 years 

 the cultivation of 'mums has made 

 great strides. The size of bloom Is 

 due to improved methods of cultiva- 

 tion quite as much as to an Improve- 

 ment in the varieties by selection of 

 sports and cross-breeding. 



Stock Plants 



Roots selected for this purpose 

 should either be planted in a bench 

 or left In their pots in a cool house. 

 Great care should be exercised when 

 selecting stock, avoiding those which 

 are weak and show long spaces be- 

 tween the leaf joints. The short, 

 stocky growths are best. Cuttings 

 can be taken in January and until 

 April, depending on the kind of plants 

 needed. Those grown as specimens 

 should be rooted early. The longer 

 the growing season, the better will be 

 the chances for obtaining i?ood buihy 

 plants. The main crop should be root- 

 ed in March, but a few for late flower- 

 ing can be rooted in April. The early 

 flowering varieties should be E,iven at- 

 tention first. Put the cuttings in a 

 sand bed. During the rooting process 

 a high temperature should be avoided, 

 45 to 50 degrees F. being about right. 

 Shade during sunny weather and also 

 keep them syringed. When the roots 

 are one to two inches long, they 

 should be potted Into 2%-inch pots, 

 using soil a little lighter than that for 

 ordinary potting, keeping them in the 

 same temperature and syringing on all 

 favorable occasions. Do not allow 

 them to dry out. Directly the pot is 

 full ot roots repot Into four-inch, and 

 so on until the flowering pot is 

 reached. 



Plants grown as specimens should 

 be potted on into eight-Inch or ten- 

 inch pots, and pinched back two or 

 three times. This operation depends 

 on the quantity ot bloom needed. The 

 final pinching should be done about 

 the last week in July. Each stem 

 should be supported with a wire or 

 wooden stake. Varieties grown single 

 stem are those that have good stiff

stems. Turner, both yellow and 

 white, Mrs. Drabble, Meudon, Mrs. 

 Stevenson and J. Frasier are excellent 

 for this purpose, as well as many 

 others. These plants are useful for 

 decorating a conservatory, either 

 placed among palms or other foliage 

 plants or in groups, and in developing 

 large flowers this is an ideal system 

 of arrangement. 



Cuttings rooted in February and 

 potted on into six-inch or seven-Inch 

 pots will, If properly handled, make 

 beautiful specimens. Cuttings can 

 also be rooted during March to sup- 

 ply shorter plants. All lateral growth 

 should be removed, and care taken 

 not to injure the main stem, because 

 if the outer skin is damaged the re- 

 sult is a one-sided flower. To extend 

 the season of the latest flowering 

 varieties, cuttings should be rooted In 

 April, and kept in a growing condi- 

 tion to prevent the wood from getting

hard. Growing points of previously 

 potted cuttings make good material. 

 Give lots of water and close observa- 

 tion. Both are necessary to success. 



Some of the single and pompon 

 varieties should be in every collec- 

 tion. They are easily grown and use- 

 ful for decorative purposes, especially 

 for side benches. To grow good 

 specimens two or three plants can be 

 potted Into eight-Inch or nine-inch 

 pots, and if pinched back a few times 

 make beautiful specimens. Three or 

 four wire stakes placed around the 

 Inside of the pot and tied with rafBa 

 give all the support needed. 



Varieties. 



It would be useless to recommend 

 any good collection, as there are sev- 

 eral hundred known species, and it 

 is a matter of taste as to which are 

 the best. The pompon types axe
