Iron (last updated 24 June 2008 )

The picture on the right shows a young chrysanthemum plant showing yellowing of upper leaves and growing tip. Chlorosis due to severe Iron deficiency tends to affect the entire leaf rather than the inter-veinal affects of other disorders. 

Severe deficiency may also reduce leaf size and cause stunting of growth. Flowering may be delayed and flower colour paler.

Excess iron manifests itself as deep red colouration in the veins of older leaves within a few days of planting. 


Iron Deficiency 
Remedial Actions
For deficiency apply iron sequestrene dissolved in water.

For excess iron consider flooding to attempt to reduce the level of iron.
