GROWING DAHLIAS FROM SEED 



by Fred S. Heal 



Dahlia plants grown from seed planted in March or early 

 April, if given proper attention during the growing season, will 

 flower the same year and make tubers of sufficient size to winter 



Plan ting 

 Place some good dry garden loam in a box or flat, smoothing 

 even, then place the seeds on top of the soil, firm the seeds on the 

 soil with a piece of board or other flat surface article, then cover 

 seeds with sand to a thickness of a lead pencil or in other words 

 not over 14-inch, firming the sand as above described. Wet 

 thoroughly and place in a moderately warm place shaded from the 

 sun for 48 hours, then place in the sun-keeping the soil moist, 

 never letting the seed bed dry out. 



The plants should be transplanted into pots, where they 

 should remain until planting time which is in this climate after 

 May 15th. 



INSECTS AND DISEASES OF CHRYSANTHEMUMS 



AND ASTERS 



by T. A. Weston 



Editor, The Florists Exchange and Horticultural Trade World 



Outdoors, spraying with any general insecticide like nicotine 

 (Black Leaf 40) is usual for aphis on 'Mums. 



As to Asters, the black stemrot is a plague everywhere. 

 Plants must not be set on ground where the disease has been 

 apparent. Soil for sowing should be treated with formaldehyde a 

 week or two before use. One ounce of this chemical mixed with 

 2 gallons of water should be used to well soak the soil and then 

 cover with bags for a week. Allow to stand another week, when 

 it can be used. Much Aster disease starts from the soil the seed is 

 sown in, and it may be so in your case. Lime the ground when 

 plowing, and when planting out beware of setting the plants deep. 

 Don't sow too early; grow hard and stocky and allow plenty of 

 room.
