Profusion Profusion Growing Guide Zinnia x hybrida Plug Culture: 4 weeks - 200 cell Stage 1 (days 1-5) Use a well-drained media with a pH between 5.8 and 6.2 with a soil EC of <0.6 mmhos (1:2 slurry). Prior to sowing, water the plug tray to the point of drip. Then, sow the seed and cover with medium vermiculite. Do not water after sowing or the day following sowing. Then, water the seedlings as needed allowing the media to dry slightly in between watering. An overly wet soil will decrease germination. Optimum soil temperature is 76ºF/25°C. Stage 2 (days 6-10) Zinnias germinate quickly and after emergence place plug trays in a well-ventilated greenhouse with high light (3,0004,000 f.c./32,000-43,000 lux). Maintain a day temperature of 70°F/21°C and a night temperature of 65°F/18°C. A light application of fertilizer at 50-100 ppm N will greatly benefit in helping to establish strong and healthy seedlings. Stage 3 (days 11-21) Water and fertilize zinnias as needed to maintain healthy plugs. An application of 100-150 ppm N is recommended at least once a week. Watering just before wilt is recommended to avoid lush growth. One should water thoroughly to prevent high EC levels, (>1.0 mmhos 1:2 slurry). Watering early in the morning allows the foliage to dry thoroughly and prevents potential disease problems. If necessary, one can apply B-Nine (daminozide) at 0.25% / 2,500 ppm to check growth 15-17 days after sowing. Stage 4 (days 22-28) Zinnias develop rapidly and are often ready to transplant after three weeks, depending upon the plug cell size used. One can drop the air temperature to 62°F/17°C to hold plug trays for a few days. Avoid temperatures below 60°F/16°C as this will invite disease problems. Lighting: Zinnia Profusion flowers more quickly under short day length (<12 hours). To delay flowering and build plant body, especially for larger pots, extend the day length to 14 hours or use 4 hour night interruption beginning with seedling emergence until transplant. Profusion Knee-High is similar. If sown under short day conditions, it will initiate earlier and stay more compact. If sown under long day conditions (early June), it will delay flowering and grow taller. Media: Peat-lite mixes work well at a soil pH of 5.5 - 6.2. Flowering Photoperiod Long Days In warm southern regions Profusion ultimately grows to 18 in./45 cm tall by 24 in./60 cm wide, less in northern regions.

Sensitive to boron deficiency, supply 0.25 ppm B at each watering. pH Optimum pH is 5.5 - 6.2 E.C. 1.0 to 1.2 mmhos (1:2 slurry) 1 part media mixed with 2 parts distilled water.

For higher density cell packs (36-48 count) it is best to sell plants green (no flowers). For less dense cell packs (12-18 count) and 4 in./10 cm pots sell in color. Plug Stage •Full color range, in both single and double flower forms, provides good retail assortment Disease: Zinnia Profusion has good disease tolerance and is not generally attacked by the many foliar diseases that affect zinnia. Good sanitation and growing culture will also aid in keeping the plants healthy. In the landscape, do not place heavy mulch around the base of the plants as this may cause stem rot at the soil line. 6-10 in. pots, 10 in. baskets Finish Time •Disease and heat tolerant Fertilizer: To produce high quality plants, apply 100 - 150 ppm N (constant liquid feed) from a cal/mag fertilizer. Optimum EC level is 1.0 - 1.2 mmhos (1:2 slurry). Zinnia is sensitive to boron deficiency which is characterized by tip abortion, crinkled leaves and leaf edge burn. Apply 0.25 ppm of boron with each fertilizer application. Finished Production: 5-8 weeks Pot / Containerer •Easy to produce, low cost and quick turns Temperature: Zinnia is sensitive to cool temperatures (<60°F/16°C) which can invite disease and foliage problems. Warm temperatures (>75°/24°C) induce quicker stem elongation and stretching. Growers should base decisions on local climate conditions and past growing experience. The chemical and growth regulator rates listed are generally accepted practices but in no way constitute a mandate. In all cases, strict adherence to local laws and label instructions is expected.

Low cost, reliable germination, and the ideal combination of rapid but controlled growth makes this a profitable crop under a wide range of conditions. Compact, uniform plants make attractive retail displays. Profusion Double This All-America Selections Gold Medal and Fleuroselect Gold Medal winning series is an excellent landscape, bedding and container variety, producing vivid blooms in diverse climates. Profusion is disease tolerant to alternaria and powdery mildew, the two main scourges of garden zinnias. Being heat tolerant, it adapts to both hot, dry conditions and hot, humid conditions. Continuous new flower canopies keep plants looking fresh and colorful. Zinnia In the Garden Profusion ultimately grows to 18 in./45 cm tall by 24 in./60 cm wide. Final plant height and width is dependent on length of growing season, fertility, temperature, and frequency of watering. In general, plants will grow larger in southern regions than in northern locations. Space 12 - 16 inches apart based on climatic conditions. •Maintenance free in the garden •Masses of large flowers, 2 - 2.5 in./5 – 6 cm in diameter, all season long • Naturally compact and well branched Double flowers on compact, well-branched plants. Doubles and singles have similar habit and timing which facilitates easier scheduling and growing.
