POINSETTIA POINTER:
“Feed aggressively, beginning around day 7, to avoid yellowing. Pinching fairly early, between days 14 and 16, can deter uneven branching.” – James Doukas
Propagation • Roots rapidly; plant from a liner at 22-24 days. • Apply rooting hormone at the base of cutting. • Start feed program at day 7. CULTURE THAT WORKS
Growing On • Grows steadily once the branches develop, and exhibits moderate growth through mid-October, then slows somewhat as it approaches finish. • Northern Climate: Apply chlormequat chloride spray at 750-1,000 ppm. • Southern Climate: Higher rates of chlormequat chloride – up to 1,200 ppm as a spray – can be used. Later applications of chlormequat chloride spray at 500-750 ppm should end by October 10. • Micro paclobutrazol drenches can be used beginning in early October. Late Growing Stages • Very strong root system requires continuous feed until finished. • Reduce feed levels if media EC increases too rapidly, as this indicates the plants' need for nutrition is waning. • High EC at finish can result in root damage, reduced shelf life and possible Pythium . • Can be held cool. Pay attention to the humidity and avoid dew point to prevent Botrytis . • Cool down temperatures to avoid color fade in the red. • If holding in the greenhouse past initial ripening, apply a paclobutrazol spray of 5-10 ppm precisely at first pollen to help retain cyathia and reduce fade. Perform this application only at full color; no more bract expansion will occur thereafter.
• Medium-vigor variety; may require low levels of PGR application in propagation. Spray 500 ppm chlormequat chloride at day 18-20. • Plant into the finished container when well rooted. • Feed aggressively; failure to feed early enough will result in yellowing and hardening. Early Finished Growth • Strong-branched varieties. Pinch early to avoid uneven branching: at day 14-16 from a liner; at day 24-26 for direct stick. • Apply light PGR when branches are 1-1.5 in. (2.5-4 cm) using chlormequat chloride spray at 250-500 ppm to even out branches. • Prevention strategies for Pythium and Rhizoctonia are recommended shortly after planting into finished containers.
