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.
Recommended 5 weeks
72–74 °F (22–23 °C)
Comments: Starcluster Pentas are slow rooters, so provide sufficient temperature during propagation. Sprays of B-Nine ® WSG (2,500 ppm) are generally sufficient. 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. Allow the flower stem to grow 0.5 cm before pinching to ensure a good hard pinch.

Comments: Dekko Petunias have moderate vigor and are generally less vigorous than 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 PGR to absorb into the leaf tissue.
