GENERAL POTTING 



CONTAINERS: We suggest a pot with these 

 minimum dimensions: 9" deep and top dia- 

 meter of 73^". Be sure that the pot has ade- 

 quate drainage holes. 



POTTING SOIL: It should be a loose, 

 loamy mixture containing up to 30% peat moss. 



UNPACK: Unpack the roses at the potting 

 area, and be sure to keep them moist all of the 

 time. 



TRIM PLANTS: To ensure a well-balanced 

 finished plant, trim the canes back to about 

 9" from the bud union. 



POTTING: Place a layer of soil in pot. Place 

 the bush in the center of the pot with the bud 

 union just below the rim, and fill the pot with 

 soil. Tamp it firmly around the roots to elimi- 

 nate air pockets. A piece of old broom handle 

 is an ideal tamper. 



WATER: Give plants a thorough soaking as 

 soon as possible. This is most important! 



PLASTIC COVER: Place plants in green- 

 house or glass frame. Cover all plants with a 

 sheet of 2 mil plastic. This is a MUST; 

 otherwise canes will dry out and plants will die. 



Starting Potted Roses in Greenhouses 



TEMPERATURE: Place plants in greenhouse with a night 

 temperature of about 50°. 



COVERING: Cover plants with clear polyethylene. Shading 

 with some material such as newspaper may be necessary on sunny 

 days. 



SYRINGING: Keep plants moist enough so that moisture is 

 present on the underside of the film. 



REMOVE COVER: Remove the covering when new "breaks" 

 are about an inch long. This takes ten days to two weeks. Growth 

 from then on is a matter of moisture, temperature, sunshine. 60° 

 to 65° night temperature and 75° during the day is ideal. 



SPRAY PROGRAM: As the first leaves appear, start a weekly 

 program of preventive maintenance. Use a commercial rose 

 spray or a combination of Phaltan, Diazanon and Tedion for 

 general control. For mildew, use Actidione. Use manufacturers' 



recommendations 

 and be sure to 

 spray both under- 

 side and upper 

 surface of foliage. 

 If you can't spray, 

 use a reliable dust 

 instead. 



FEEDING: Feed 

 with water-soluble 

 fertilizer as used 

 on other container- 

 grown plants. Ap- 

 ply when first leaves 

 are fully developed 

 and continue once 

 every two weeks. 



PLACE OUT- 

 SIDE: As soon as 

 the danger of frost 

 is past and plants 

 show sufficient 

 growth, they can be 

 moved to outside 

 display selling areas.
