SME 0.5–1.0 mS/cm Comments: Irrigate early in the day to avoid leaf scorch when high light levels are present. Allowing the soil surface to dry between irrigations will reduce algae growth. Light is not essential for emergence, but additional light at 14 hours per day will greatly enhance germination and early growth. Maintain high humidity until day 14 when it can be reduced to around 50%. Once out of the chamber, it is helpful to cover trays with Reemay ® or similar to help retain humidity and reduce irrigation frequency. Avoid irrigating with cold water. 65° F (18° C) is ideal.

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 reduce 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.

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.

MEDIA pH/EC
288-cell tray pH: 5.5–5.9 SME 0.5–0.75 mS/cm Comments: Tuberous Begonias will form tubers and single flowers under short days so providing night interruption lighting for a total of at least 14 hours is necessary, even in the plug stage. During the early stages of growth, irrigate very gently since Begonia seedlings are very small and heavy watering will disturb the roots. This is a relatively long plug crop so keeping the media too wet can lead to excessive algae growth. Pelleted 7–8 weeks 1 No 7–10 days 73–78 °F (23–26 °C) Required for germination
