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 2-3 days and after cuttings become fully hydrated.
Recommended 3.5-4 Weeks 70-74 °F (21-23 °C)
Comments: Darla has moderate vigor and will generally need a PGR treatment in propagation. To control growth after rooting, sprays of B-Nine ® WSG (2,500 ppm) or Florel ® (350 ppm) are sufficient. It is also becoming popular for growers to combine Florel ® (350 ppm) with the B-Nine ® WSG (1,500 ppm) to increase growth control and to improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants. Do not spray B-Nine ® WSG or Florel ® + B-Nine ® WSG tank mixes 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.

72-74 °F (22-23 °C)
Comments: To control growth after rooting, a spray of B-Nine ® WSG (3,500-4,000 ppm) can be used. Sprays of Configure ® (150-300 ppm) or Atrimec ® (200 ppm) can also be used to improve branching on the young rooted plants. These Configure or Atrimec sprays should be applied to actively growing plants and done ideally before pinching. Do not spray B-Nine ® WSG, Configure, or Atrimec 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.

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 750-1,000 ppm and under hot conditions with a tank mix spray of Cycocel ® (1,000 ppm) + B-Nine ® WSG (2,500 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.
