Gazania can be propagated in various tray sizes including 72, 84, and 105’s. Propagation Cycle: 5 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 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.
- SunBathers will benefit from the use rooting hormone. Time to root and uniformity in rooting will 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 6-9 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.
- Gazania should not be pinched in propagation but will benefit from lower leaf removal when the cuttings are stuck.
- Light trimming of the larger leaves will also prevent problems with botrytis.
Choose a media with the following traits:
- Good aeration
- Porosity between 5-15%
- Avoid excess irrigation and fertilization while plants are establishing which can lead to slow root development. Once plants are established the media should be allowed to dry to touch between irrigations. Wet media will promote stretch while excessive drying will delay flowering and result in foliage burn under high light levels.
- Fertilizer Regime
- Begin fertilizing 2 weeks after transplant.
- Choose a complete balanced fertilizer complete with minor elements.
- Apply 200-250 ppm constant liquid feed.
- Choose a fertilizer that is low in ammonia and phosphorus.
- 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 5.8-6.2
- Optimum EC is 2 to 2.5 mmhos. Provide periodic clear water application if excess salts accumulate.
SunBathers 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.
Establishing temperature: 62-68°F/17-21°C average daily temperature
Temperatures for growing on: 68°F/21°C average daily temperatures and 55-60°F/13-17°C night temperatures
- SunBathers will tolerate lower temperature but flowering may be delayed.
- Avoid high day temperatures combine with moisture stress.
- Maintain relative humidity below 70% and provide good air circulation to avoid problems with botrytis.
SunBathers prefer bright light. For best results
- 5000 candles/53,800 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
- SunBathers should not be pinched.
Plant Growth Regulators
Adequate spacing and good light levels are the best way to control stretch. If needed, SunBathers respond to:
- B-Nine® as a spray at 2500 ppm
- Cycocel® 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
- Root and stem rots

*Total crop time may be increased with cooler temperatures. Late PGR application will also increase crop time.
