Ranungulus Pot 10,50cm
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 up flowering. High temperatures in combination with long days will stimulate corm formation or promote leaf yellowing.

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 up flowering. 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 18 hours. 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. 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 applications can be applied until flowers begin to open.
Common Diseases: Cercospora ranunculi, Pythium Root Rot, Botrytis, Tomato Spotted Wilt
Virus Common Pests: Aphids, Whitefly, Leaf miner, Thrips, Fungus
