Yellow Leaves on Plants
Yellowing leaves are your plant's distress signal. Here's how to read what it's telling you — and fix it fast.
What Causes Yellow Leaves?
Nitrogen Deficiency
Pattern: Overall pale/yellow, starting with older (lower) leaves first
Fix: HealthyEarth Lawn Fertiliser or VegePro
Iron or Manganese Deficiency
Pattern: Yellow between veins, green veins remain (interveinal chlorosis)
Fix: FoliMax chelated foliar spray
Magnesium Deficiency
Pattern: Yellow from centre outward on older leaves
Fix: FoliMax (contains Mg) or Epsom salt flush
Overwatering / Root Rot
Pattern: Yellowing with soft or mushy stems at base
Fix: Reduce watering; apply SilicaMax to stimulate root zone recovery
High Soil pH
Pattern: Widespread yellowing unresponsive to fertiliser
Fix: Soil test recommended; FoliMax bypasses pH barrier via leaf
