Propagation of Unrooted Cuttings
Root emergence: 10–12 days Rooting hormone: Recommended, especially if propagation temperatures are not ideal. A 0.1% (1,000 ppm) IBA concentration using either powder or liquid formulations can be applied to the lower portion of the cutting stem. Be careful not to coat the leaves or entire cutting–excess application can cause burning and damage to the cutting. Another option is to apply an overhead heavy spray to the cuttings (penetrating the rooting media) using water-soluble K-IBA at 250–300 ppm 24–48 hours after sticking. Do not use overhead applications of alcohol-based IBA solutions (ex. Dip ‘n Grow ® ). Bottom heat temp: 72–74 °F (22–23 °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. Cold mist water sitting on Nirvana ® XDR foliage can cause severe leaf and growing tip distortion. To prevent this, many growers propagate Nirvana ® XDR cuttings using plastic tents or Reemay ® fabric to provide a very humid, warm environment without excess mist water sitting on foliage. Rec. tray size: 105-cell (30 mm) or larger Propagation timing: 4.5–5 weeks for a 105-cell tray add more rooting time for significantly larger tray sizes. Tech Tip: Starting Nirvana ® XDR from a callused cutting can help increase rooting speed by up to 2 weeks, promote rooting uniformity and robust vegetative growth for a faster finish quality liner. Keep young plants fertilized during propagation to prevent bottom leaf yellowing. Temperature

1. Nirvana ® XDR vinca is highly resistant to 20 isolates including ten of the most virulent strains of Phytophthora nicotianae that cause Phytophthora blight on annual vinca, confirmed in collaboration with Clemson University and in independent trials across North America. However, they are not immune to the disease. 2. For this reason, we highly recommend chemical rotations as a responsible and critical part of a disease resistance maintenance program. 3. Applications are also advised to control several other diseases that can infect vinca, such as Thielaviopsis , Rhizopus , Rhizoctonia , Pythium and Tospovirus (INSV and TSWV). Nirvana ® XDR simplifies production with fewer fungicide applications to keep your vinca crop healthy.
Day: 72–74 °F (22–23 °C) Night: 72–74 °F (22–23 °C) Average Daily Temperature: 72–74 °F (22–23 °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 Daily light integral (DLI): 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.
