Bacopa can be propagated in various tray sizes including 84’s and 105’s. Stick two cuttings per cell. Propagation Cycle: 3 weeks


  • 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

  • Bacopa 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.


  • Average days with mist vary from 6-8 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.

Fungicide Applications

  • Within 48 hours after sticking apply a fungicide spray for prevention of botrytis.

Growth Regulators

  • Growth regulators should not be necessary.


  • Pinching or sheer cuttings in week 2 of propagation.


  • 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

Growing On

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.
  • Fertilizer Regime
    • Begin fertilizing 2 weeks after transplant
    • Choose a complete balanced fertilizer complete with minor elements
    • Apply 200-250 ppm constant liquid feed
    • Alternate with calcium nitrate or a cal –mag fertilizer on a regular basis. 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.

Bacopa can be grown successfully at a wide range of temperatures but for best results the crop should be established warm. As root growth and top growth begins temperatures can be reduced.

Temperature regime:

Establishing temperature: 65°F/18°C average daily temperature

Temperatures for growing on:60-70°F/13-21°C day and 55-60°F/11-13°C night

At lower temperatures:

  • Growth will be slower and time in production longer

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.

Bacopa prefers bright light.

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

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

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)

  • Apply a preventative fungicide application for botrytis at the time of pinch. Do not apply mist of water immediately after any hard pinch.

Plant Growth Regulators
Good light levels and cultural practices are the best means of controlling stretch.

If needed, Bacopa responds to:

  • B-Nine® as a spray at 1500 ppm

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

Insect and Disease Concerns

  • Fungus gnats
  • Whiteflies


  • Botrytis
  • Root and stem rots
