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
3–3.5 weeks 70–74 °F (21–23 °C)
Comments: Fun House Petunia has good vigor and generally will need chemical growth regulation in propagation. To control growth after rooting, sprays of B-Nine ® WSG (2,500–3,500 ppm) are effective. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (2,500 ppm) can also be used to control growth and improve branching. Do not spray Florel ® on stressed or weak cuttings. For Fun House Potpourri Petunia applying B-Nine ® WSG alone or in combo (1,250 ppm) with Florel ® may impact the bicolor floral pattern to have a greater yellow expression at finish. 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.
