What is Chlorosis?

Question

define the word and how can i prevent it? where does it come from?

Answer 1

Chlorosis in plants is a result of nutrient deficiency, insufficient light, or certain viral diseases, and causes the leaves to become yellowish from lack of chlorophyll being created within the plant.

The most common form is Iron Chlorosis which is a result of a deficiency of Iron in a plant. Iron is a key element in the creation of chlorophyll. Iron Chlorosis is caused by a plant being unable to extract sufficient Iron from the soil. It is very common in high pH and heavy clay soils. These types of soils bind up the iron into a form that the plant cannot use properly.

Iron Chlorosis will effect the young leaves first and then spread to the older foliage as the condition worsens. If the new growth turns yellowish first, this is the likely problem.

Some plants are very tolerant of high pH and clay soils, while others are not. The best way to prevent it is to either choose plants that are tolerant, or amend the soil to improve the chances of your plants being able to extract the iron in the soil.

Iron chlorosis is usually associated with deficiency or unavailability of iron in the soil or a form of iron that is difficult for the plant to extract, but it may also appear when roots are damaged by overwatering, poor drainage, or overfertilization. Any condition that kills roots or does not allow feeder root development can lead to iron chlorosis.

There is a foliar form of iron that you can spray directly on the leaves or injected into the soil where the roots can easily absorb it. This can alleviate the problem somewhat, but it is best to do what you can to correct it if possible.

Treat iron chlorosis by eliminating the cause. A soil test will determine soil pH. Alkaline soil, or soil which is not acid enough, may be treated with sulfur or iron sulfate to make it more acidic. Poorly drained soils should be improved and plants subject to iron chlorosis should be watered carefully. The color of plants several months after soil is amended will indicate need for future treatment.

Answer 2

Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. Possible causes of chlorosis include poor drainage, damaged roots, compacted roots, high alkalinity, and nutrient deficiencies in the plant. Nutrient deficiencies may occur because there is an insufficient amount in the soil or because the nutrients are unavailable due to a high pH (alkaline soil). Or the nutrients may not be absorbed due to injured roots or poor root growth.

Answer 3

Define Chlorosis

Answer 4

Simply put, chlorosis is yellowing of the leaves. Think of the word Chlorophyll and connect it with disorders.. -osis. The plant is not producing chlorophyll as it should. The most common cause is nutrient deficiency from soil alkalinity or lack of a particular micronutrient in the soil. Lack of light can also cause it.

Check your soil pH.. should be (most plants) 5.7 to 6.5 range for proper nutrient uptake.

Answer 5

It's the yellowing of the leaves, which can be caused by numerous problems, such as nutrient imbalance or improper watering. The best thing to do is to research your plants so that you know exactly what they need, that is, sun exposure, water requirements, soil requirements, fertilizer requirements, hardiness, pruning details, etc. Every plant is different and needs to be understood to be taken care of properly.

Answer 6

You have a manganse or Zinc defiency. Check with your nursery and they could tell you more. I am sure that plants could die if not properly cared for that has this. Alot of ppl check their ph soil balance also.
