foliar spray on Pelargonium
Quick answer
If your Pelargonium has foliar spray, the most likely cause is: Combined application of Moringa extract (6g/L) with 50% NPK chemical fertilizer produces herb and essential oil yields equal to or exceeding full-dose NPK fertilization alone. The synergistic effect occurs because Moringa's cytokinins and growth hormones amplify the plant's ability to metabolize chemical nutrients, reducing fertilizer requirements by 50% while maintaining or increasing yields.
Start here:
- 1. Prepare NPK solution at 50% of recommended dose (e.g., if full dose is 600kg/fad ammonium sulfate, use 300kg)
- 2. Apply soil drench of NPK solution every 4 weeks during growing season

How to reverse foliar spray on Pelargonium
- 1
Prepare NPK solution at 50% of recommended dose (e.g., if full dose is 600kg/fad ammonium sulfate, use 300kg)
- 2
Apply soil drench of NPK solution every 4 weeks during growing season
- 3
Prepare Moringa extract at 6g/L working concentration
- 4
Apply Moringa foliar spray 1 week after each NPK application
- 5
Spray until just before run-off, covering all leaf surfaces
- 6
Continue 4 applications total, spaced 4 weeks apart
- 7
Monitor plant response: if vigor exceeds expectations, reduce NPK to 25% in subsequent cycles
Keep foliar spray off this Pelargonium
Never mix extracts together in the same tank - apply NPK to soil first, then Moringa as foliar spray 7 days later. Reduce NPK to 50% when combining with Moringa extract to avoid salt toxicity. Monitor leaf color to adjust NPK levels.
