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

Comments: Day extension lighting to 14 hours required in propagation. Cut flower dahlias have 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.
