Garden Specifications
Garden height: 8–12" (20–30 cm) tall
Garden width: 10–14" (25–35 cm) wide

USDA zone: 9–11
AHS zone: 1–10

Propagation of Unrooted Cuttings
Root emergence: 10–12 days
Rooting hormone: Not recommended
Bottom heat temperature: 72–75 °F (22–24 °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. Applying too much mist early on can lead to foliar disease and tissue breakdown.
Recommended tray size: 72-cell (35 mm)
Propagation timing: 6 weeks for a 72-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)
Lighting
Day extension lighting: Necessary to 14 hours to prevent tuberization and premature flowering.
Light intensity: 1,000–1,200 foot candles (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 3,000 foot candles (600 µmol·m−2·s−1) as rooting increases and the cutting matures.
Day length response: Facultative short 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 50 ppm nitrogen when roots become visible. Rates can be increased up to 100 ppm nitrogen after roots become well developed. Use primarily Cal-Mag® Plus (calcium nitrate + magnesium nitrate) fertilizers in propagation to prevent unwanted stretch.
Pinching: Recommended
Plant growth regulators (PGRs): Spray Altercel® plant growth regulator at 500–1,000 ppm (chlormequat chloride).
Finishing
Temperature
Day: 72–74 °F (22–23 °C)
Night: 72–74 °F (22–23 °C)
Average daily temperature: 73 °F (22.5 °C)
Lighting
Day extension lighting: Beneficial to 14 hours
Light intensity: 1,200–1,600 µmol·m−2·s−1
Day length response: Facultative short day
Daily light integral (DLI): 16–18 mol·m−2·d−1
Transplanting: Transplant directly into the finished container. Place the rooting media slightly above the level of media in the container. Make sure that the root ball is covered and that the plug is situated in the center of the pot. IMPORTANT: When planting, place liners with the leaf tips pointing towards to the outside of the container for best plant growth and flower presentation.
Media pH: 5.8–6.2
Media EC: SME EC: 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm
Fertilizer: 200–250 ppm N
Pinching: Yes, 1 soft pinch is recommend either in propagation or 7–10 days after transplant.
Plant growth regulators (PGRs): PGRs are not usually required. However, if needed Adora Begonias during finishing respond well to sprays of Altercel® at 5,00–1,000ppm, or sprays of A-Rest® at 5 ppm.
Tech tip: Day extension lighting to 14 hours is recommended for the first weeks of finished production to bulk plant size. Lighting should be discontinued at least four weeks prior to shipping flowering plants.
Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 2 and 3. 2 - MEDIUM: Soil is light brown in color, no water can be extracted from soil, and soil will crumble apart. 3 - MOIST: Soil is brown in color, strongly squeezing the soil will extract a few drops of water, and trays are light with no visible bend.
Common pests: Thrips, Broad Mites
Common diseases: Botrytis, Tospovirus, Xanthemonas
Postharvest: Try Chrysal Alesco®, a postharvest foliar spray, to protect ethylene sensitive crops during shipping and retail.
Scheduling
| Size | Crop Time | Plants Per Pot |
|---|---|---|
| 1.0 quart (4.5 to 5 inch) | 6–8 weeks | 1 ppp |
| 1.25 to 2.5 quart (5.5 to 6.5 inch, trade gallon) | 8–10 weeks | 1 ppp |
| 3.0 quart to 2.0 gallon (7.5 to 10 inch) | 10–14 weeks | 2–3 ppp |
| 1.5 gallon hanging basket (10 inch basket) | 10–14 weeks | 3–4 ppp |
Estimated finish crop time is from transplant of a 105-cell tray and finished at an average daily temperature (ADT) of 73 °F (22.5 °C).
Example crop schedule for a 2.5 quart
| Weeks From Transplant | Description |
|---|---|
| 1 week | Provide average daily temperatures of 73 °F and DLI levels above 12 mol·m−2·d−1. If needed, use supplemental lighting to provide 14 hours of light per day |
| 2 weeks | Soft pinch if not done in the liner stage |
| 3 weeks | Apply a spray of copper-based fungicide for prevention of bacterial diseases. Scout for insect pests and spray as needed throughout crop cycle |
| 4 weeks | Apply a spray of Altercel® at 500–1,000 ppm if needed for growth control |
| 6 weeks | Apply a broad-spectrum fungicide drench to prevent late-season basal stem and root rot diseases |
| 8 weeks | Finish |
