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. Happy Days Dahlia 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 (1,500–2,500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350–500 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 PGR to absorb into the leaf tissue.

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.

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. 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. Avoid dehydration of the cuttings before sticking in propagation.

A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (1,500–2,500 ppm) can also be applied to control growth and improve branching. Cuttings of Scentropia Heliotrope are sensitive to chilling, so avoid storing cuttings <50 °F (10 °C). Stick unrooted cuttings immediately upon arrival—they do not like to be stored. Avoid over-misting during propagation.

Comments: To control growth, sprays of Bonzi ® (1–2 ppm) are generally used. Growers can also spray Florel ® (250–300 ppm) at 1–2 days after sticking unrooted cuttings to reduce premature flower bud development and help provide more uniform (but delayed) flowering during finishing. This is a good strategy for baskets or large patio pots where early flowering is not desired.
