    Good Evening Sylvia, I have to say that to me it looks like rust disease ... here is a weblink that talks about the 3 most common diseases that attack Plumeria. Rust won't kill it, but it WILL cause it to lose all its leaves :(

    Needs to be treated as well as water a lot. Get a solution from your garden center

    Seems like a fungal disease. Try treating it with fungicide. don't over water and expose to sunlight as Plumerias thrive better in full sun. It's supposed to help the plant to recover. Also, check those branches in the 2nd picture if it's already hollow. try pinching it. If it is, cut the whole branch off as the disease could easily spread to other parts of the plant.

    I have several nice sized plumeria plants on a 3rd floor west facing balcony. Unless weather (heat) conditions are extreme I only water once a week. Over watering plumeria often leads to a type of root/stem rot that can result in the leathery, shriveled bark texture seen in the second photo.

    If you live in America, your nearest university will probably have a Master Gardener's Program which offers free advice and more to community members. You can email your pictures, speak on the phone or go in person with a sample of the plant for help. You may also find the help you need on their website alone. Good luck!

    I checked Plumeria diseases on Google and can't tell from the photo, but you could have pinhole borers which aren't good, or lichen which are just unsightly. Our plumerias aren't old enough yet to really have much experience with them and pests or disease. You should take your problem to professionals, they can diagnose the problem and give you straight advice faster than us hometalkers. Good luck!

    I agree with Dorothy Eller regarding scale insect. A homemade white oil treatment would be a good start, many recipes can be found on the web from ingredients from your kitchen. You can also remove them physically with a soft toothbrush dipped in the white oil if the infestation is not too severe and you have the patience. You may also find a trail of ants who "farm" the scale and distribute it for the sweet discharge exuded by the scale pests.

    Lowes carries a product for tree's that is systemic manufactured by Bayer. This product is a 3 in 1 systemic, take of pest or fungus. I have been a horticulturalists for over 30 years and it has never failed me. Make certain you follow this directions and water it in slowly. I use an old gallon jug to mix it in and pke a small hole in the bottom. Next spring your plant should be fine.

    Good luck!

    Plumerias hate wet roots. Make sure if it's potted, that pot is not sitting in a fish to collect the excess water. Good luck.

      I do the same with mine...but sometimes water it in winter. Would it do alright in Nebr. without watering it till it goes outside in spring? I took a chance this spring and propagated it into 3 new plants....they took ( to my happy surprise!) One even bloomed!!!!
