Culture Information
Erysistible™
Erysimum
Erysimum linifolium
Product form: Vegetative
Containers: Quarts, Gallons
Habit: Upright
Garden Specifications
Garden height: 16–22" (40–56 cm) tall
Garden width: 12–16" (30–40 cm) wide
Exposure: Full sun
USDA zone: 5–9
AHS zone: 9–5
Product use: Containers, Landscapes, Combos
Propagation of Unrooted Cuttings
Root emergence: 10–14 days
Rooting hormone: Recommended. A quick dip at 250-500 ppm of K-IBA has been found to be more beneficial than an overhead spray. Overhead sprays tend to cause hard, gnarled growth.
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. 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: 6–7 weeks for a 105–cell tray; add more rooting time for significantly larger tray sizes.
Temperature
Day: 66–68 °F (19–20 °C)
Night: 64–66 °F (18–19 °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: 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 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 fertilizers in propagation to prevent unwanted stretch.
Pinching: Recommended
Plant growth regulators (PGRs): Not necessary
Vernalization
Vernalization: Not required (first year flowering)
Finishing
Temperature
Day: 64–66 °F (18–19 °C)
Night: 60–62 °F (16–17 °C)
Average daily temperature: 64 °F (18 °C)
Lighting
Day extension lighting: Necessary to 14 hours
Light intensity: 800–1,200 µmol·m−2·s−1
Day length response: Facultative long day
Daily light integral (DLI): 14–16 mol·m−2·d−1
Transplanting: Transplant directly into the finished container. Place the rooting media slightly below the level of media in the container. Make sure the root ball is covered and the liner is situated in the center of the pot.
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: 125–175 ppm N
Pinching: Yes, 1 pinch is recommended in propagation 7–10 days prior transplant leaving 4–6 leaf nodes.
Plant growth regulators (PGRs): If necessary, apply a Bonzi® spray at 30 ppm, or Sumagic® spray at 5 ppm.
Tech tip: Erysistible™ erysimum's cold hardiness allows it to be produced in the fall and finished for early spring sales.
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: Aphids, whiteflies
Common diseases: Downy mildew, powdery mildew
Scheduling
| Size | Crop Time | Plants Per Pot |
|---|---|---|
| 1.0 quart (4.5 to 5 inch) | 5–6 weeks | 1 ppp |
| 1.25 to 2.5 quart (5.5 to 6.5 inch, trade gallon) | 6–7 weeks | 1 ppp |
Estimated finish crop time is from transplant of a 105-cell tray and finished at an average daily temperature (ADT) of 64 °F (18 °C).
Example crop schedule for a 2.5 quart
| Weeks From Transplant | Description |
|---|---|
| 1 week | Transplant one pinched liner into the center of the container. |
| 4 weeks | If needed, apply sprays of PGR to reduce height and stiffen the plant to make it ready to ship. Avoid PGR applications after bud set as they may bury the flowers beneath the foliage. |
| 6 weeks | Finish |
