Canna Mono Hierro ( Fe )

It plays the major part in photosynthesis and a large part in the production of chlorophyll. Furthermore it has a big influence on physiological processes and on the energy system.

CANNA Iron can be absorbed directly, can be mixed with all fertilisers and is stable with each pH. It is a perfect product to replenish iron deficiency and to stimulate the growth and bloom.

Symptoms of a deficiency

Iron deficiency can occur during periods of heavy growth or high plant stress and is characterised by a strong yellowing of the young leaves and the growth shoots between the veins. This occurs chiefly because iron is not mobile in the plant. The young leaves can’t draw any iron from the older leaves. With a serious iron shortage, the older leaves and the smaller veins in the leaf can also turn yellow.

Development of a deficiency

• Green/yellow chlorosis, from inside to the outside in the younger leaves and in the growth shoots. The veins remain mostly green.
• Continued yellowing of the leaves to sometimes almost white. Also, large leaves turn yellow. This inhibits growth.
• In serious cases the leaves show necrosis, and the plant’s growth and flowering are inhibited.

Reasons for a deficiency

• The pH in the root environment is too high (pH> 6,5).
• The root environment contains a lot of zinc and/or manganese.
• The concentration of iron is too low in the root environment.
• The root temperature is low.
• The root medium is too wet, causing the oxygen supply in the roots to stagnate.
• The root system functions inefficiently due to damaged, infected or dead roots.
• There is too much light on the nutrition tank; light promotes the growth of algae. Algae also use up the iron and break down iron chelates.
