Why do my hibiscus leaves turn yellow?

There are several reasons why Hibiscus leaves can change to yellow. First, if only interior leaves are involved, the process is normal. If the entire plant is turning yellow, it may indicate root loss from excessive watering/root rot. Let the plant dry out a little, do what you can to improve drainage, and pray. If the leaves are yellow with green leaves, the plant may need nitrogen (use a balanced fertilizer) or iron (use Ironite or cheleated iron). Lastly, check the undersides of the leaves to see if white fly insects have infected the plant. You may be able to see the little white insects fly around the plant. The undersides may have white or gray threads (you'll know it if you see it). White flies are a huge problem on many species of hibiscus and is best treated with pesticide or horticultural oil. Small infestations can be controlled by spraying the leaves daily with water.

Yellowing leaves could be indicative of many problems. It could be too much sun, not enough sun, too much water, iron deficiency, needs to be fertilized.
Reply:Believe it or not, plants do lose some of their leaves naturally! As plants get taller and age, sometimes they shed their lower leaves in producing new leaves closer to the top of the plant. That is why people cut back certain plants each year, to maintain that full, shrubby look.





It could also be a nutrient deficiency. If the lower leaves are yellowing, that means you have a nitrogen deficiency. Nitrogen will relocate to the upper leaves of the plant, leaving lower leaves yellow. If the new leaves are yellow, it is probably a micronutrient deficiency.





If the plant is yellow all over, it probably means something else is going on, like maybe your water got contaminated with something, which could turn the leaves yellow. Could have been a misapplied pesticide.





You'd have to rule those out in order to find the culprit!
