Potting and Growing 



ROSES 



Display and Selling 

 of Potted Roses 



Display Area — Potted Roses will 

 thrive if displayed on a moist 

 medium, preferably 4 to 6" of 

 sawdust, shavings, peat or simi- 

 lar material. 



Caution: Avoid placing Potted 

 Roses on hot, dry, black-top 

 surface paving areas. 



Care — Maintain a regular water- 

 ing, spraying and feeding pro- 

 gram. Remove old blooms to 

 encourage new growth. 



Plunging — After mid-June plunge 

 the Potted Roses in about 4 to 

 6" of moist sawdust, peat, shav- 

 ings or similar material. Roses 

 cared for in this manner will be 

 saleable until late October.

Starting Potted Roses in Polyethylene Houses 



Potted roses can be started extremely well and with a minimum 

 of expense in polyethylene houses by following these basic tips: 



1. IF STARTING POTTED ROSES UNDER POLYETHYL- 

 ENE WITHOUT HEAT . . . 



(a.) Re sure to cover house with clear polyethylene. Milky poly 

 tends to cut down too much on heat from the sun's rays, slow- 

 ing up forcing. 



(b.) VERY IMPORTANT: Use a second covering of poly 

 immediately over the pots setting on the ground. This will 

 enable you to maintain an almost air-tight condition, thereby 

 keeping the humidity around the canes of the plants at all 

 times. Humidity is vitally important for assuring fast -breaking 

 plants. 



2. IF YOU ARE STARTING POTTED ROSES IN A 

 HEATED POLYETHYLENE HOUSE . . . 



(a.) We suggest you use a milky poly. This enables you to 

 maintain a more constant temperature in the house by cutting 

 down on the contrast between cloudy and sunny days . . . you 

 control temperature through your inside heat, 

 (b.) We suggest the use of a black poly on the ground under the 

 plants in a heated house, too, as it gives better control between 

 the ground temperature and the inside temperature of the 

 house. 



Starting Potted Roses in Cold Frames 



PLACING: After potting, place roses in cold frames and water 

 thoroughly. 



COVERING: Cover plants with polyethylene. Keep moist at all 

 times. Do not be concerned with overwatering at this time. 



REMOVE COVERING: When "breaks" are about an inch long, 

 remove half the covering, preferably on a cloudy day to avoid sun 

 damage to shoots. Remove remainder three days later. 



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

 program of preventive maintenance. Use commercial rose spray 

 or a combination of Phaltan, Diazanon and Tedion for general 

 control. For mildew, use Actidione. Use manufacturers' recom- 

 mendations and be sure to spray both the underside and the upper 

 surface of foliage. If you can't spray, use a reliable dust. 



FEEDING: Feed with water-soluble fertilizer as used on other 

 container-grown plants. Apply when first leaves are fully devel- 

 oped and continue once every two weeks. 



CAUTION: If clear polyethylene plastic is used to cover the 

 frames, do not allow water to collect in depressions in the plastic. 

 The sun's rays passing through collected water are intensified and 

 may damage the plants. Milky or shaded polyethylene is best.
