method of culture have preferred to take plants directly into the house 

 as soon as they are potted. This may be done but stockier plants will 

 result if they are grown out-of-doors or in a coldframe. A feeding just 

 as buds are sizing will usually add to the life of the plant. 



Cooperating with us in trying this method of culture of chrysanthe- 

 mums under home conditions. 1 1 members of the Tilton-Xorthfield 

 Garden Club reported the following success: 



.Most plants were grown in cool, sunny windows until thev were 

 ready to flower. While in bloom, plants were subjected to night tem- 

 peratures from, 45 c - ~0~ F and day temperatures from 60° - 70°F. All 

 reported plants required water daily or every other day. Plants were 

 decorative from about 50 to 50 days with those lasting the longest at 

 cooler temperatures. In general, club members were quite successful in 

 growing these plants. 



Troubles 



The tarnished plant bug sometimes causes severe injury on chrysan- 

 themums in the held causing poor branching and blind-growth. If plants 

 are left in the garden until flower buds are initiated, which occurs on later 

 varieties in late August or early September, there is danger of the de- 

 formed flowers and blind-growth shown in Fig. 14C. A good coverage 

 of fine sulphur dust applied after each rain will give good results as a re- 

 pellent to this insect. If the plants are potted and taken from the gar- 

 den before August 20, there is usually little or no danger from injury to 

 the flowers. 



Woodchucks sometimes find chrysanthemum plants particularly 

 palatable, especially when they are making tender new growth. A sul- 

 phur dust coverage is helpful in repelling them. 



Aphids are probably the most common insects to attack chrysan- 

 themums indoors. If possible, it is well to spray plants thoroughly with 

 blackleaf 40 or some other contact insecticide before bringing them in. 

 It is sometimes necessary to spray stock plants during winter and spring.
