Copper (last updated 24 June 2008 )

Copper deficiency 
Omission of this element from a soilless compost can prevent flowering in year round chrysanthemums. In the picture to the right the plants are the same age however the plant on the left is exhibiting symptoms of copper deficiency

Less severe deficiency can result in delayed flowering and compounding of sprays. 

Leaves remain uniformly light/pale green, bloom size is reduced and bloom quality suffers.

Affected plants develop chlorosis of the leaves.  The leaf on the right shows the affect compared with the normal leaf on the left.

Remedial Actions
The recommended way to resolve a copper deficiency is to spray with copper sulphate.
