Magnesium Deficiency in Banana
Commonly affects: Musa acuminata, M. balbisiana (Banana)
Yellowing appears between the leaf veins on older leaves while veins stay green, sometimes with a reddish-purple tinge along the margins.
Potential Causes
- 1Magnesium-poor soil, common in sandy or heavily leached growing media
- 2High potassium fertilisation competing with magnesium uptake
- 3Cool soil temperatures reducing root uptake efficiency
Solution Steps
- 1Apply a diluted Epsom salt solution as a soil drench or foliar spray
- 2Repeat every 3-4 weeks until new growth shows normal colour
- 3Balance potassium feeding with adequate magnesium in the fertiliser programme
Prevention Tip
A diluted Epsom salt drench every few weeks is a simple, effective magnesium supplement for banana plants showing this pattern.
