B-Nine/chlormequat chloride tank mix at 3,000/1,000 ppm applied at 10-14 days or when roots hit the edge of the cell. Configure 300 ppm or Florel 300 ppm will increase branching. Stick cuttings immediately upon arrival to avoid breakdown.

Avoid wide fluctuations in soil moisture. Apply preventative fungicide drench at 18-21 days after sticking. Must pinch 14‑16 days after stick. It would be typical to have 6 to 8 leaves remaining below the pinch. Propagate in long days.

Ethylene sensitive – stick as soon as possible. Flower buds are common in propagation. Reduce mist as soon as possible. Apply preventative fungicide spray after sticking. Reduce mist as soon as possible. Stick immediately upon arrival. Geraniums are best rooted in media in strip form to allow for maximum airflow and avoid foliage overlap. After initial rehydration, careful misting is required to optimize callus and root initiation. Mature leaves should show slight wilting at midday and regain turgor in the late afternoon under ideal mist conditions. Leaf petiole wilting indicates undermisting. Overmisting leads to Botrytis. Remove flower buds at transplanting. Stick immediately upon arrival. Geraniums are best rooted in a media in strip form to allow for maximum air flow and avoid foliage overlap. Ivy geraniums require 25-30% less mist in propagation compared to zonals. Propagate under separate mist programs. Remove flower buds at transplanting. Stick immediately upon arrival. Geraniums are best rooted in media in strip form to allow for maximum airflow and avoid foliage overlap. After initial rehydration, careful misting is required to optimize callus and root initiation.
