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
3–3.5 weeks 70–74 °F (21–23 °C)
Comments: Itsy Petunia has moderate vigor and generally is not as vigorous as many full-trailing petunia types. To control growth after rooting, sprays of B-Nine ® WSG (2,500 ppm) are usually sufficient. 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 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.
