Outback Daisy Mini Yellow™, Mauve Delight, & Jumbo Mauve™

Propagation

Brachyscome can be propagated in various tray sizes including 32,50,72,84 and 105’s. Stick two cuttings per cell. Propagation Cycle: 4 weeks

Media

  • Choose a well-drained aerated propagation media.
  • Avoid media containing peat moss which will hold too much water.
  • Choose a blended media with other components or inorganic media such as Oasis® or Rockwool®.

Bottom Heat

  • Bottom heat will promote healthy root development.
  • Maintain bottom heat at 70-75°F/21-24°C.
  • Mist will cool the media temperature. Monitor media temperature closely and frequently.

Rooting Hormones

  • Brachyscome roots easily without the use of rooting hormone. However, time to root and uniformity in rooting may be improved with use of a hormone.
  • Either liquid or powder formulations work equally well. Choose a product with up to 2500 ppm IBA or up to 500 ppm NAA.

Misting

  • Average days with mist vary from 6-9 days depending on environmental conditions in the greenhouse.
  • Mist cuttings so they remain turgid but avoid over misting that results in saturated media.
  • Over misting will result in slow rooting and possible problems with root rot and botrytis.
  • Mist should be eliminated or significantly reduced as roots form.

Growth Regulating

  • Growth regulating should not be necessary.

Pinching

  • Pinch or shear cuttings in week 2 of propagation to improve plant habit and correct stretch.

Fertility

  • Begin feeding as roots are visible. Begin with 75 ppm nitrogen then increase to 150 ppm. Choose a fertilizer with low levels of ammonium based nitrogen and avoid overhead feeding with fertilizer containing phosphorus.
  • Maintain pH at 5.6-5.9
  • Maintain EC at 0.75-0.80 mmhos.

Growing On

Media
Choose a media with the following traits:

  • Good aeration
  • Porosity between 5-15%
  • Sterile

Irrigation/Fertilization

  • Avoid excess irrigation and fertilization while plants are establishing which can lead to slow root development. Do not allow mature plants to dry excessively.
  • Fertilizer Regime
    • Begin fertilizing 2 weeks after transplant.
    • Choose a complete balanced fertilizer complete with minor elements.
    • Apply 200-250 ppm constant liquid feed with a fertilizer low in phosphorus.
    • Additional iron may be needed – apply as iron chelate or iron sulfate (always rinse foliage when using iron sulfate).
    • A slow release product may also be used to supplement a constant liquid feed program and may provide improved performance for the consumer.
  • Maintain pH between 5.5-6.3
  • Optimum EC is 2 to 2.5 mmhos. Provide periodic clear water application if excess salts accumulate.

Temperature/Humidity
Brachyscome can be grown successfully at a wide range of temperatures but for best results the crop should be established and grown cool.

Establishing temperature: 55°F/13°C average daily temperature

Temperatures for growing on: 55-70°F/13-21°C day and 50-55°F/11-13°C night

  • At cooler temperatures growth will be more compact and flowering more prolific.
  • At warmer temperatures excess vegetative growth may be a problem.

Relative Humidity:

  • Maintain relative humidity below 70% and provide good air circulation to avoid problems with botrytis.

Light
Brachyscome prefers bright light.
Provide:

  • 4000 foot candles/43,100 lux minimum
  • 6000 foot candles/64,600 lux maximum

*Shade may be required to avoid high temperatures but can encourage stretch and delay flowering.
*Plants grown outdoors in full sun stay compact and may yellow in response to high light.

Spacing
Establish plants pot tight than space to:

  • 4” pots – 5-6” centers (approximately 2 per sq. ft.)
  • 6” pots/1 gallon – 14” centers
  • 8” pots – 18” centers

Pinching
1st Pinch- week 2 of propagation
2nd Pinch- trim once established (1-2 weeks after transplant)
Additional Pinch- shape, correct stretch or time to flower (mature plants will flower 5-6 weeks after pinch)

Plant Growth Regulators
Good light levels, cool growing conditions, and good cultural practices are the best means of controlling stretch.
If needed, Brachyscome responds to:

  • B-Nine® as a spray at 2500 ppm

*Apply any PGR applications prior to visible bud set to avoid delay in time to flower.

Trouble Shooting

SYMPTOM: Slow Growth
Possible Solutions

  • Check root systems for signs of damage. Treat with fungicide drench and reduce watering/ fertilization until roots regrow.
  • Check root systems for insect causing damage, particularly fungus gnat larvae or root aphids. Treat with pesticides targeted to control these pests.

SYMPTOM: Yellowing of young leaves
Possible Solutions

  • Check that fertilizer injectors are functioning properly.
  • Ensure media pH is between 5.5-6.3 – adjust if necessary.
  • Check iron levels in soil and tissue. Supplement with iron sulfate drenches if media pH is high or with iron chelate as a spray or drench, if media pH is normal.

SYMPTOM: Yellowing of lower foliage
Possible Solutions

  • Check that fertilizer injectors are functioning properly.
  • Check for low nitrogen levels in soil and tissue.
  • Check E.C. levels of soil for high salts.
  • Check magnesium levels in soil and tissue.
    Supplement with magnesium sulfate as a drench if levels are low.SYMPTOM: Drying and discoloration of foliage
    Possible Solutions
  • Plants allowed to dry out. Maintain proper watering regimen.
  • Phosphorous levels in fertilization program may be too high. Use low phosphorous or no phosphorous fertilizer mixes.

Insect and Disease Concerns
Insects

  • Aphids
  • Caterpillars
  • Fungus Gnats
  • Scale
  • Thrips

Diseases

  • Botrytis
  • Powdery Mildew
  • Root and stem rots
  • Viruses
