New hibiscus leaves are shriveling up and looking burnt

I just purchased two hibiscus. They are planted next to each other. I live in Arizona and it's pretty hot. I covered up both with a sheet about four feet above them. I water them real good every day. One is ok and the other's leaves are turning a dark brown and white. It starts in the center of the leaves. They are shriveling up. This is the second hibiscus I got at home depot that have done the same thing. I'm pretty confused about this and am tired of taking these back and getting new ones.
these are cut from the hibiscus..on plant of course was the same..lots of them

    Why did you cover the plants?

    Looks like burn: sun or chemical (incecticide, herbicide...). Is it possible?

    could be in shock from transplanting. Mix epsom salt and water till the salt dissolves and water your plants it will help

    I also live in AZ and have hibiscus; they are in big pots under a patio cover. I have had them about four years. I water once a week or when the leaves tell me they are thirsty. I cut them back in the fall and spring and have had no problem with them. Also, purchased at Home Depot.

    Epsom salt will make the leaves happy. Mix a couple of tablespoons into a gallon of water.

    They might be in shock. I transplated a small one from one spot in my yard to another. After I transplanted it the leaves did the same as yours--all of the leaves. I just left the bare little tree alone--didn't pull it out of the ground and sometime later noticed it was getting new leaves. It was a miracle because it looked completely dead.

    Coffee grounds and egg shells spread onto the soil around your plants, once every week or two will help get them healthy again. My grandma's old trick for her garden, plants and fruit trees.

    It sounds like a insect problem. I had a similar problem and tried many natural suggestions found through Google. However, none worked. Continued researching and found Bayer Advanced 12 Month Tree & Shrub. I used the granules and within a week I saw improvement. The two hibiscus plants affected are fine.

    I also live in Az., our water tends to be somewhat "salty", whether it's well water or city water. This looks a lot like "salt burn". Flushing the built up salts out of the soil is helpful, but difficult if planted in the ground and not pots. Contact your local County Extension office, they probably have Master Gardeners who can pin point the problem and help you resolve it - and it's free expert advice! They are familiar with local conditions and happy to help :)

    With any new planting you have to be patient. I live in central Florida and have the same thing happening. I water and watch and just know my beautiful hibiscus will be Gorgeous next year. Hang in there:)

    turn the leaves over and see if you see tiny tiny white mites on them. HD has a problem with their hibiscus and mites

    When lèves turn brown it means you water too much, too often. Let dry before watering again. Good luck, Monique.

    after planting do not put too much water.
  • Deanna Nassar Deanna Nassar on Sep 21, 2016
    Should only water when soil gets dry. Mist the leaves with just plain water.

    To me that looks like sunburn. Any possibility something could be reflecting and burning the leaves. It doesn't look like a insect issue. Where are they sitting or planted?
