Mandevilla hybrida Dipladenia MADINIA ® / MADINIA ® MAXIMO / MADINIA ® PETITE REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME
PINCH
PROP TIME BOTTOM HEAT
105-cell (30 mm) or larger
URC, CC
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.
Recommended 5–6 weeks
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 Atrimmec ® (200 ppm) can also be used to improve branching on the young rooted plants. These Configure ® or Atrimmec ® sprays should be applied to actively growing plants and done ideally before pinching. Do not spray B-Nine ® WSG, Configure ® , or Atrimmec ® 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.
Muehlenbeckia axillaris Muehlenbeckia COINS REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME
PINCH
PROP TIME BOTTOM HEAT
105-cell (30mm) or larger
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.
Optional
5–6 weeks
70–72 °F (21–22 °C)
Comments: Recommend sticking two cuttings per cell. Because cuttings are small, it is important to provide enough mist to keep the cuttings turgid. Excessive mist can inhibit rooting and increase the chance of disease.
Osteospermum ecklonis Osteospermum TRADEWINDS ® REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME
PINCH
PROP TIME BOTTOM HEAT

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 2–3 days and after cuttings become fully hydrated.
Not recommended
4.5–5 weeks 70–74 °F (21–23 °C)
Comments: Do not reduce mist too soon during propagation. Continue light misting until all cuttings are rooted into the media. Reducing mist too early can result in slow and uneven rooting across the bench. To keep plants under control, a spray of B-Nine ® WSG (2,500 ppm) or B-Nine ® WSG (2,500 ppm) + Altercel ™ (1,000 ppm) can be applied after cuttings are well-rooted and vegetative growth begins. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (2,500–3,500 ppm) can also be used to control growth and improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants and done ideally before pinching. 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 plant growth regulator (PGR) to absorb into the leaf tissue. Pelargonium interspecific Geranium Interspecific CALDERA ™ / CALIENTE ® / CALLIOPE ® CASCADE / CALLIOPE ® LARGE / CALLIOPE ® MEDIUM / MANTRA ™ / MOJO ™ / MOXIE! ™ / PRETTY LITTLE ™ REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME PINCH PROP TIME BOTTOM HEAT 105-cell (30 mm) or larger URC, CC 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 3.5–4 weeks 70–74 °F (21–23 °C) 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 Interspecific Geranium growth can be controlled using sprays of Altercel ™ at 750–1,000 ppm and under hot conditions with a tank mix spray of Altercel ™ (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 plant growth regulator (PGR) to absorb into the leaf tissue.
