What is Chlorosis

Chlorosis is a disease that can affect your plants, it is defined by a lack of chlorophyll in the plant leaves.

Chlorophyll is a pigment in the cells of plant leaves and is responsible for photosynthesis. Plants rely on the process of photosynthesis to produce sugars to feed themselves. Without chlorophyll plants cannot support themselves and will shrivel and eventually die.


The most visible sign of chlorosis in plants is the yellowing and eventual whitening of the plant leaves. This may only affect a certain number of leaves or the entire plant may be affected, depending on the severity of the condition.

Chlorophyll is responsible for the green colour of plant leaves and the discolouration of chlorotic leaves is due to the lack of chlorophyll.


Chlorosis is usually caused by a lack of nutrition, this can be due to poor soil quality or damaged roots.

However, it can also be caused by a soil which is either too acidic or alkaline for the plant.


If you notice signs of Chlorosis in your plants, one way to treat them is with a nutritional supplement, although this is only a short-term solution as the underlying problems will remain.

The better strategy is to solve the problems with the soil, whether this is a problem with the pH or a lack of soil quality.
