Vernalization: Required Garden Specifications
Garden height: 6–10” (15–25 cm) tall Garden width: 10–12” (25–30 cm) wide Exposure: Part Sun–Full sun USDA zone: 4–8 AHS zone: 8–1 Product use: Containers, Landscapes, Combos Propagation of Unrooted Cuttings Root emergence: 10–12 days
Rooting hormone: Recommended. A K-IBA basal dip at 250–300 ppm at sticking has been shown to hasten rooting. Bottom heat temperature: 70–72 °F (21–22 °C) for the first three weeks. After roots are well developed, temperatures can be lowered to hold and tone the cuttings. Misting: Mist schedules vary depending on light and temperature conditions. Apply just enough moisture to rehydrate the cuttings and keep them from wilting. Cuttings should be hydrated and in a non-wilted stage within 24 hours after sticking. Cuttings that continue to wilt heavily after 24 hours will callus unevenly and will be delayed in rooting. 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 in rehydration of the cuttings. Misting should be significantly reduced after 3–4 days and after cuttings become fully hydrated. Recommended tray size: 30 mm (105-cell) or larger Propagation timing: 7-8 weeks for a 30 mm (105-cell) tray; add more rooting time for significantly larger plug sizes. Temperature
Daily light integral: 4–6 mol·m -2 ·d -1 for the first two weeks after sticking or until root development occurs. DLI can be increased to greater than 12 mol·m -2 ·d -1 after root formation. Media pH: 5.6–6.0 Media EC: SME EC: 0.9–1.3 mS/cm, Press/Squeeze Method EC: 1.4–2.0 mS/cm Fertilizer: Begin fertilization at 80 ppm nitrogen when roots become visible. Rates can be increased up to 150 ppm nitrogen after roots become well developed. Use primarily Cal-Mag ® Plus (calcium nitrate + magnesium nitrate + iron) fertilizers in propagation to prevent unwanted stretch. Pinching: Recommended Plant growth regulators (PGRs): Not necessary Bulking and Vernalization Vernalization: Required Bulking Bulking Time: See Scheduling Section Temperature: 64–66 °F (18–19 °C) Pinch: No PGR: Not necessary Vernalization Vernalization Time: 7–8 weeks Temperature: 37–40 °F (3–4 °C) Tech tip: Avoid pinching after the first week in September to avoid cutting off the next years flowers.
Day: 70–72 °F (21–22 °C) Night: 66–68 °F (19–20 °C) Lighting Day extension lighting: Not necessary
Light intensity: 200–250 µmol·m -2 ·s -1 for the first two weeks after sticking or until root development occurs. Light levels can be increased up to 600 µmol·m -2 ·s -1 as rooting increases and the cutting matures. Day length response: Day neutral
