VEGETATIVE PROPAGATION

Dahlia SINCERITY Dahlia 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.

Not recommended

3.5–4 weeks 70–74 °F (21–23 °C)

Comments: Day extension lighting to 14 hours required in propagation. Sincerity Dahlia has a moderately vigorous habit and may require a plant growth regulator (PGR) treatment in propagation. If needed to control growth after rooting, sprays of B-Nine ® WSG (1,500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350–500 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 PGR to absorb into the leaf tissue.

Diascia DARLA ® Diascia barberae 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 3.5–4 weeks 70–74 °F (21–23 °C)

Comments: Day extension lighting to 14 hours required in propagation. Darla Diascia has moderate vigor and will generally need a plant growth regulator (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.

Dipladenia MADINIA ® / MADINIA ® MAXIMO / MADINIA ® PETITE 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: PGRs not needed. Control by pinching if needed.

Comments: To control growth after rooting, a spray of B-Nine ® WSG (1,500-2,500 ppm) can be used.

Geranium Interspecific CALDERA ™ / CALIENTE ® / CALLIOPE ® CASCADE / CALLIOPE ® LARGE / CALLIOPE ® MEDIUM / MANTRA ™ / MOJO ™ / MOXIE! ™ / PRETTY LITTLE ™ Pelargonium interspecific 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 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.
