Fun House ™ Black Widow
Petunia Fun House ™ Culture Guide Petunia x hybrida Product form: Vegetative Containers: Quarts, Gallons, Hanging Baskets Habit: Mounding Garden Specifications Garden height: 10–14” (25–35 cm) tall Garden width: 18–22” (46–56 cm) wide Exposure: Full sun USDA zone: 9–11 AHS zone: 11–2 Product use: Containers, Hanging Baskets, Landscapes, Patio Pots, Combos Propagation of Unrooted Cuttings Root emergence: 6–8 days Rooting hormone: Not recommended
Bottom heat temperature: 70-74 °F (21-23 °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 2-3 days and after cuttings become fully hydrated. Petunias are particularly sensitive to over- misting. Petunias root quickly and applying too much mist can lead to chlorotic and deformed foliage and growing tips. Recommended tray size: 30 mm (105-cell tray) or larger Propagation timing: 3–3.5 weeks for a 105-cell tray; add more rooting time for significantly larger cell sizes. Temperature
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: 200–240 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: Facultative long day
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. 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 100 ppm nitrogen when roots become visible. Rates can be increased up to 200 ppm nitrogen after roots become well developed. Use primarily Cal-Mag ® Plus (calcium nitrate + magnesium nitrate) fertilizers in propagation to prevent unwanted stretch. Supplemental feeding with additional iron (i.e., iron chelate) will help prevent iron deficiency and leaf tip chlorosis. Pinching: Not recommended Plant growth regulators (PGRs): Fun House ™ petunias have good vigor and generally will need chemical growth regulation in propagation. To control growth after rooting, sprays of B-Nine ® WSG (2,500–3,500 ppm) are effective. 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.
