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: Grandalia Dahlia has moderate to high vigor and will generally need plant growth regulator (PGR) use 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.
