72–78 °F (22–26 °C)

Not required for germination pH: 5.5–5.9

SME 0.5–0.75 mS/cm Comments: Avoid overwatering to help prevent excess algae growth and to promote root growth into the media. If germinating on the bench it is helpful to cover trays with ReeMay ® or similar to help retain humidity and re- duce irrigation frequency. When irrigating use low pressure/volume nozzles/breakers to avoid moving seeds around in the cell. If the daily light integral (DLI) is less than 12 mols/day adding supplemental HID light will promote a more uniform crop. Do not use plug trays that have been used previously and had a crop treated with paclobutrazol grown in them. Most Begonia semperflorens will stop growing if exposed to any level of paclobutrazol. Do not irrigate with recycled water for this reason.
