Calendula CALEO ™ Calendula 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 in rehydration of 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: To control growth after rooting, a spray of B-Nine ® WSG (2,500–3,500 ppm) can be used. 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.
Calibrachoa CABRIO ™ Calibrachoa hybrida REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME
PINCH
PROP TIME BOTTOM HEAT
105–cell (30 mm) or larger.
URC, 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 in rehydration of the cuttings. Misting should be significantly reduced after 2–3 days and after cuttings become fully hydrated.
Recommended 4.5–5 Weeks 72–74 °F (22–23 °C)
Comments: Cabrio Calibrachoas are compact-medium growers and should not need the typical growth regular in propagation that other more vigorous varieties require. To keep plants under control, a spray of B-Nine ® WSG at 1500–2500 ppm can be applied after cuttings are well-rooted and vegetative growth begins. It is also becoming popular for growers to combine Florel ® at 350–500 ppm with the B-Nine ® WSG solution listed above to increase growth control and to 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 ® or Florel ® + B-Nine ® 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.

Comments: Callie calibrachoas have a range of vigor, with some being relatively compact to others having more of a medium to medium-vigorous habit. To keep plants under control, a spray of B-Nine ® WSG at 1,500–2,500 ppm can be applied after cuttings are well-rooted and vegetative growth begins. It is also becoming popular for growers to combine Florel ® at 350–500 ppm with the B-Nine ® WSG solution listed above to increase growth control and to 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 PGR to be absorbed into the leaf tissue.

Recommended
Comments: Helichrysum italicum is a bushy, dense-growing plant. It typically does not require any chemical growth regulation in propagation. Transplant on time to avoid stretched growth.
Dahlia DAHLEGRIA ® 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 in rehydration of the cuttings. Misting should be significantly reduced after 2–3 days and after cuttings become fully hydrated. Not
3.5–4 Weeks 72–74 °F (22–23 °C)
Recommended
Comments: Dahlegria is vigorous growing and will need a PGR treatment in propagation. To control growth after rooting, sprays of B-Nine ® WSG (2500–3500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350–500 ppm) + B-Nine ® WSG (2500 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.
