Find out what the term chlorosis means and how it can affect your houseplants. Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. Find out if your plant has it, what causes it and what to do. Iron, manganese and zinc deficiencies can cause chlorosis. Curing chlorosis often requires that you adjust the pH in your houseplant soil before the plant can uptake nutrients.

In this installment of houseplant terminology, today’s term is chlorosis. Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. The main symptoms of chlorosis are pale leaves that turn a yellowy lime green color, with dark green veins. Initially, you’ll notice the veins remain green, while the leaf itself begins to yellow. This process becomes more pronounced as chlorosis progresses.
Several causes can lead to chlorosis, including poor drainage, damaged roots, high alkalinity, and nutrient deficiencies. The high alkalinity and nutrient deficiencies are interconnected. If the soil is too alkaline, the plant won’t be able to absorb certain nutrients effectively.
One of the primary nutrient deficiencies that causes chlorosis is a lack of iron. When the pH is too high, the plant cannot absorb iron, even if you fertilize with it. Deficiencies in manganese or zinc can also lead to chlorosis, as these problems often arise from imbalanced pH levels. Additionally, a shortage of potassium can reduce the availability of iron to the plant.
Chlorosis can also occur due to inadequate fertilization. By properly fertilizing the plant, you can help eliminate chlorosis. I have a video coming up with more information on chlorosis and how to deal with it, and I have covered this topic in several other videos as well.
As mentioned, this is a terminology video so that you understand what the term means when you read about it or encounter it in another video. If someone tells you your plant is chlorotic or suffering from chlorosis, you’ll know what they are talking about.

FAQs about Chlorosis
What is chlorosis?
Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll.
What are the symptoms of chlorosis?
The main symptoms of chlorosis are pale leaves that turn a yellowy lime green color, with dark green veins. Initially, the veins remain green while the leaf itself begins to yellow, and this process becomes more pronounced as chlorosis progresses.
What causes chlorosis?
Several causes can lead to chlorosis, including poor drainage, damaged roots, high alkalinity, and nutrient deficiencies. High alkalinity and nutrient deficiencies are interconnected, as soil that is too alkaline prevents effective nutrient absorption.
What nutrients are commonly deficient in chlorosis?
A lack of iron is a primary nutrient deficiency causing chlorosis. Other deficiencies, such as manganese or zinc, can also contribute, particularly when pH levels are imbalanced. Additionally, a shortage of potassium can reduce the availability of iron to the plant.
How can I treat chlorosis in my plants?
Chlorosis can occur due to inadequate fertilization. Properly fertilizing the plant can help eliminate chlorosis. Regular monitoring of pH levels and nutrient availability in the soil can also assist in preventing chlorosis.
Where can I learn more about chlorosis?
There are videos available that provide more information on chlorosis and how to deal with it. This terminology video aims to help you understand what chlorosis means when discussing your plants.
