depends on what is the cause of the clorosis. lack of iron? zinq? magnazium? maybe too much water? try adding compost and a fertizer that includes micronutrients
It is considered that the acidification of the soil and the adding of soluble magnesium salts combat chlorosis.
Plants have chloroplasts which contain chlorophyll, and if there is decrease in chlorophyll due to less availability of magneseium or nitrogen in the soil, then this results in Chlorosis.
The best for a rose is: ~Water ~Sunlight ~Salt Remember that every flower need soil. == ==
An iron provider is the type of fertilizer which will cure chlorosis in a garden plant's leaves.Specifically, chlorosis comes from the ancient Greek word khloros ("greenish yellow, pale green") and suffix -osis ("sickness"). Proper plant and soil health demand certain levels of specific nutrients, of which one is iron. Iron deficiency will manifest itself in yellowed plant leaves. Its treatment will require any of the following options:Foliar sprays of chelated iron or ferrous sulfate (effective in two or three days);Soil applications of elemental sulfur (effective in two or three months) or iron sulfate (effective in two or three weeks) in the case of low soil pH interfering with nutrient uptake;Trunk injections of ferric ammonium citrate or iron sulfate in the event of a garden tree being affected.
It's because of the soil type, they need acidic soil!!
Chlorosis is the termed used for yellowing of leaves due to low content of chlorophyll. The cause of chlorosis is due to deficiencies in soil of substances like iron, magnesium, or nitrogen.
A rose gets its nutrients from the soil. The rose draws the nutrients through the roots that are in the soil.
Iron chlorosis is an iron deficiency in the plant that shows itself with yellowed leaves, usually between the veins which remain green. Sometimes the entire leaf can turn yellow or white. It usually does not mean that the soil is deficient in iron, but that the iron is not available in a form that the plant can use. This most commonly happens when the soil is strongly alkaline - greater than pH 7 and lime is present. One way to treat it is to lower the soil pH and to ensure the soil is well aerated and drained.

Growing rose requires a soil rich in organic matter. A humus-rich soil would be ideal for this purpose.
Black soil is needed for the growth of roses.
potted soil, vermiculite
Soil on the heavy side of loam is best but most will do.
