TECH TIPS
Usually not required. Plant growth can be controlled best through proper moisture, feed and temperature management. If needed due to environmental conditions sprays of Cycocel ® at 500–1,000 ppm or B-Nine ® WSG/Cycocel ® tank mixes at 1,500 ppm B-Nine ® WSG/300 ppm Cycocel ® are effective. Avoid spraying with B-Nine ® WSG during the last few weeks of crop time to avoid reducing flower size.
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. 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.

TECH TIPS
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.
Proper management of moisture, fertilizer, and light is the best way to control growth. If needed, Bossa Nova Begonia responds well to sprays of B-Nine ® WSG at 1,500–2,500 ppm.
