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 rehydrate the cuttings. Misting should be significantly reduced after 3–4 days and after cuttings become fully hydrated.
Recommended 2–3 weeks
68–70 °F (20–21 °C)
Comments: B-Nine ® WSG at 1,500–2,500 ppm can be used to control stem stretch.

Comments: Lanai Verbena has a range of vigor, with most varieties having medium to medium-vigorous growth habits. To control growth after rooting, sprays of B-Nine ® WSG (2,500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (1,500–2,500 ppm) can also be used to control growth and improve branching. 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 plant growth regulator (PGR) to absorb into the leaf tissue.

4.5–5 weeks 72–74 °F (22–23 °C)
Comments: Avoid excessively cold mist water during propagation, or distorted young foliage can occur. Keep young plants fertilized during propagation to prevent bottom leaf yellowing. To control growth after rooting, sprays of Cycocel ® (750 ppm), B-Nine ® WSG (2,500 ppm), or Cycocel ® (750 ppm) + B-Nine ® WSG (2,500 ppm) can be used depending on the growth rate and vigor of the plant. The Cycocel ® + B-Nine ® WSG combo spray will have a more growth regulating effect than either the Cycocel ® or B-Nine ® WSG spray alone.
