Dipladenia MADINIA ® MAXIMO Mandevilla hybrida 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.

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 3–4 days and after cuttings become fully hydrated.

Recommended 4.5–5 weeks 72–74 °F (22–23 °C)

Comments: Not needed. Control by pinching if needed.

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 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 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 plant growth regulator (PGR) to absorb into the leaf tissue.
