URC

Not Recommended

CapSil ® (spray adjuvant) can be sprayed on the cuttings at a rate of 2–4 oz/100 gal within 1–2 days after sticking to help in rehydration of the cuttings. Misting should be significantly reduced after 3–4 days and after cuttings become fully hydrated.

Recommended 3.5–4 Weeks 72–74 °F (22–23 °C)

Comments: To control growth after rooting, a spray of B-Nine ® WSG (1500–2500 ppm) can be used.

4.5–5 Weeks 70–74 °F (21–23 °C)

Recommended

Comments: To help reduce bottom leaf yellowing during propagation (e.g., on delayed shipments or where cuttings have gotten warm during shipping), Fascination ® can be sprayed on the cuttings at 2.0–2.5 ppm within 24 hours after sticking. Caldera growth can be controlled using sprays of Cycocel ™ at 750–1000 ppm and under hot conditions with a tank mix spray of Cycocel ® (1000 ppm) + B-Nine ® WSG (2500 ppm). Bonzi ® sprays are not recommended in propagation because of the chance of getting into the rooting media and stunting the plant. Florel ® can also be sprayed at 300–350 ppm 2.5–3 weeks after sticking and after good root formation to improve branching, reduce premature flowering, and to control growth. Do not spray Florel ® on stressed or weak cuttings. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.
