How do I correct yellow leaves on my hibiscus plants?

First of all, pull all the dead leaves and the ones that come out easily. If you have to apply too much pressure to get off the leaf, its probably alive, so don't pull it out.





next, give the plant more water, or less, depending on how much u give it already. Also put some fertilizer on it. I would think about garden sulphur around your plant, since that promotes a nice, deep green color in the leaves.





I hope your hybiscus survives. They are such nice plants!

How do I correct yellow leaves on my hibiscus plants?
Inspect your plants for the mites and other bugs as Angel said. If the leaves that are turning yellow are on the lower portion of the plant, this may not be a serious problem. I have often seen older leaves yellow and drop off shortly after transplanting/potting-up. If it perists, or leaves yellow at various heights, it may be that a bit of fertilizer, especially a little iron, is in


order. Plants will often 'scavange' nutrients from older leaves to use in growing new leaves. (Are the newest leaved unfolding nice and green?)They can do this quickly. Check with your home and garden store for a fertilizer specifically for hibiscus. Resist the urge to use chemical sprays on these plants. They don't tolerate strong bug sprays well.

Reply:Whenever yellow or spotted leaves are encountered they should be picked off and trashed. As long as the number of leaves affected are small, less than 10 percent of the total number of leaves, the plant will be unaffected. Older leaves will frequently turn yellow and drop as a natural part of leaf aging. Also, sudden changes in the plant's environment, such as moving it from one location to another, can cause leaves to yellow and fall. Perhaps the greatest pest threat to tropical hibiscus house plants is spider mites. Plants with spider mites usually have leaves that loose their dark green color and look anemic, as though the plant requires a dose of fertilizer. If you look closely on the backside of the leaves with magnification you can see the tiny mites moving over the leaf. If mites are suspected, give the plant a thorough spraying with water, directing a forceful spray up under the foliage.





Hope this helps!
