VEGETATIVE PROPAGATION

Verbena LANAI ® COMPACT Verbena hybrida REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME

PINCH

PROP TIME BOTTOM HEAT

105-cell (30 mm) or larger

URC, AutoStix ®

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 rehydrate the cuttings. Misting should be significantly reduced after 2–3 days and after cuttings become fully hydrated.

Recommended 3–3.5 weeks 70–74 °F (21–23 °C)

Comments: Lanai Compact Verbena has compact-medium vigor and should require only moderate amounts of chemical growth retardants in propagation. To control growth after rooting, sprays of B-Nine ® WSG (1,500–2,500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (1,500 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.

Verbena LANAI ® UPRIGHT Verbena hybrida REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME

PINCH

PROP TIME BOTTOM HEAT

105-cell (30 mm) or larger

URC, AutoStix ®

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 rehydrate the cuttings. Misting should be significantly reduced after 2–3 days and after cuttings become fully hydrated.

Recommended 3–3.5 weeks 70–74 °F (21–23 °C)

Comments: Lanai Upright Verbena has compact-medium to medium vigor and should require moderate amounts of chemical growth retardants in propagation. To control growth after rooting, sprays of B-Nine ® WSG (1,500–2,500 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.

Vinca NIRVANA ® CASCADE Catharanthus roseus REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME

PINCH

PROP TIME BOTTOM HEAT

105-cell (30 mm) or larger

URC, CC, AutoStix ®

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 rehydrate the cuttings. Misting should be significantly reduced after 3–4 days and after cuttings become fully hydrated.

Not recommended

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 Altercel ® (750 ppm), B-Nine ® WSG (2,500 ppm), or Altercel ® (750 ppm) + B-Nine ® WSG (2,500 ppm) can be used depending on the growth rate and vigor of the plant. The Altercel ® + B-Nine ® WSG combo spray will have a more growth regulating effect than either the Altercel ® or B-Nine ® WSG spray alone.
