Ranunculus
GROWING ON
High quality Ranunculus is best obtained with cool night temperaturesand short day conditions. Low temperatures and high light levels will result in large flowers with an intense color. Transplant Ready: 8 – 10 weeks from sow in a ‘288’ tray. Finish Bulking/FlowerInitiation: Optimum conditions during the vegetative period, beginning at transplant, needed for the root to reach the edge of the container AND to make the plant receptive to flower initiation. Media:Select a porous media that drains well. This is important during the cool season when temperatures and light levels are low, and media is slow to dry. • pH: 5.8 – 6 • EC: 1.25 – 1.75 Light: 4,500 –5,000 foot candles (45,000 – 50,000 lux or 16 – 18 mols of light). Ranunculus initiates the highest flower count and the best growth under the natural days for spring production. Daylength extension incombination with high light will promote earlier flowering. Temperature: 58° – 62°F (14° – 16°C) 2 – 3 weeks, until the roots have reached the edges of pots. Once established lower temperature to 50° –55°F (10° – 13°C) OR maintain 58°F (14°C) with a -5 to -10°F (-3° to -5.5°C) DIF or morning drop. Temperatures above 68°F (20°C) may reduce vegetative growth, increase stem length and speed upflowering. High temperatures in combination with long days will stimulate corm formation or promote leaf yellowing. Moisture: Alternate between saturate (5) and moist (3); dry back must occur within 18hours. Avoid a wilting state to prevent leaf yellowing. Humidity: 40% Fertilizers: 14-4-14 or 17-5-17 at 100 – 150 ppm to maintain an EC of 1.25 – 1.75. Provide 10 – 15 ppm phosphorus. Growth Regulators:B-Nine (daminozide) at 2,500 ppm. Apply first treatment when flower buds are visible in the crown. A second application is made when flower stems are 2” (4 – 5 cm) in length. If needed, subsequent...
