Substrate for finishing.
• Suitable substrate components: peat > cocopeat > wood fiber peat > composts > natural soils. With particle size 0 ―5 mm .
•
Avoid rice husk.
•
Add 30 % leavening agent: perlite > sand > zeolite (not vermiculite)
• Substrate mixture examples :
✓
70 % cocopeat + 30 % perlite,
Provide porose substrate.
✓ 55 % cocopeat + 20 % peat + 25 % perlite,
✓ 50 % cocopeat + 20 % natural soil + 30 % perlite.

Fertigation tips.
Fed your Gazania well.
• Provide 75―125 ppm of nitrogen (N). • You can provide proper amount of N by 0.5―1.0 g/l of 17 -5-17 or 15-5-15 or similar.
Don’t apply clean water!
• Optimal EC in the water 1.5 (up to 1.7 or even 2.0 in sunny condition and hot)
• Optimal EC in the substrate (SME*): 0.5―0.75 mS/cm. Low EC and clean water will lead Gazania leaves to stretch.
* Saturated Media Extract
Public
When to transplant?
Three―four true leaves is the best stage*.
Public
How to transplant?
Gazania is crown crop.
Keep the root ball on the surface of the substrate.
Don’t bury the plant tip!

Gazania fertigation tips #1.
Before the flower buds appear.
• Provide 125 ―175 ppm of nitrogen (N). • You can provide proper amount of N by 0.8―1.3 g/l of 18-5-18, 15-3-15 or similar.
NPK: 18-5-18, 15-3-15 or similar.
• Optimal EC in the water 1.7 ―2.5 mS/cm. • Optimal EC in the substrate (SME*): 1.5―2.1 mS/cm.
Increase pH a bit .
• Substrate and water pH: 5.8―6.2.

Gazania fertigation tips #2.
After the flower buds appear.
• The same recommendations but NPK rate must be changed.
NPK: 18 -5- 40 , 15 -3- 35 , 17 -5- 30 or similar.
N/K rate must be about 1:1.5―1:2 .
✓ Never apply clean water!!! Good Fertigation Practice reminder .
✓ Provide recommended EC (1.7―2.5 mS/cm) and pH (5.8―6.2) with every watering.
✓ Don’t forget to apply Ca+Mg every 2 weeks.
