Need help identifying plumeria problem

11 years ago

Hi all;

You helped me immensely last time my beloved plumeria got sick- a year ago spider mites attacked and thanks to you all, we recovered! Well, it's sick again and seemingly with a new problem. Can anyone help me identify? Only the oldest leaves, and one at a time are being affected. If I remove the affected leaf, the next day the next oldest leaf goes. The leaves are turning yellowish and the texture is changing, but mostly I'm noticing large black spots. I've looked online at a variety of pics, but none of them seem to be what I'm looking at. Any suggestions? The leaves seem to yellow just a bit before getting the spots, so I'll admit right off the bat I panicked and used the pesticide I used to get rid of the spidermites twice over a couple days, then I watched it like a hawk. The leaf loss continued, and no signs of spidermites. It's getting a lot of filtered sun and the location in the house hasn't changed. We keep a pretty consistent temperature in the house. Does anyone have any idea what could be causing my leaf loss? If the leaf falls naturally, it ends up quite a bit more yellow than in the photo, but out of fear that it might be a fungus or something I've been plucking the leaves off when they start looking bad, sealing them and taking them away.

Here is a link that might be useful: Photos of the problem

W.O.Paradise,
What do the new leaves and branch tips look like? Any chance you can take a picture of the tips and the branches. I think that may help more.

I think once you get your plumeria acclimated to outside light and temperatures, it will grow normally again. You are putting it outside, right?

Because so many seedlings look much like named varieties but can have completely different genes, identifying plants from pictures is one of the biggest errors in the plumie world. This is one reason so many plants sold as cuttings from picture ids, turn out to be incorrect plants. If you did not buy a plant from a reputable vendor as a named variety you really are wrong to assume the plant in the picture is a named variety. For example, I had a seedling from a Vera Cruz Rose that looked exactly like a Nebel's Rainbow. Also I had a seedling from a Ryan Chelsea that looked exactly like a Lani. The high number of genes creates many variables for plant survival. I recommend people label a plant as looks like a _____ or possibly a _______. Please never sell a cutting as some plant picked from a picture. This is just wrong and has caused so much error in correct identification of registered cultivars.

I thought it may be lack of water but now that you mention the self watering system, I think it may be too much water and that you may have root rot. Repotting is always stressful to plants but you have no choice. Remove all of the soil from the roots. Some people dip the roots in hydrogen peroxide (1/2 cup per gallon water). Many people on this forum use either the gritty or 5-1-1 mix, both of which are fast draining and do not retain too much water.. The ingredients for 5-1-1 are easier to find. This is what I use: My version of Al Tapla's 5-1-1 Mix · 5 parts pine bark mulch (remove ½” pieces through 1/2 inch screen) (Some people use Repti Bark instead of mulch. They do not screen it.) Be sure to soak the bark overnight. · 1 part sphagnum peat · 1 part perlite (coarse, if you can get it) · 1 Tb garden lime /gal 5-1-1 mix (measure the 5-1-1 mix) · Osmocote plus (follow manufacturer’s instructions). This is optional. · Moisten well and wait at least 2 days before using PLEASE NOTE: Other people with many years experience growing citrus in containers do not use the above soil mixes. For example, Millet (TropicalFruitForum.com) uses 9 parts Miracle Grow Garden Soil (NOT Miracle Grow Potting Soil) to 1 part perlite. You are more likely to avoid root rot using the gritty or 5-1-1 mix.

First to Jean. You will have to google it - my phone camera isn't up to taking pictures of thrip. And the damage is minimal but I know how bad they can get quickly. Gorbelly - Unfortunately the problem manifested itself inside under lights - well no - my first indicators were inside under lights and then full manifestation revealed itself as I was hardening them off. (Peppers are hit and miss here - upon advice I plant them in early June now. That has seemed to work really well. ) Right now they are fully rooted in 4" pots with some budding - hardened off - ready to plant or give away soon - except for thrip. We have had a few chilly days so either that or my rather half hearted spraying of dead bug set them back. I hope to get some spinosad today and do a more thorough job in a few days. Another aside - now I have thrip in my house. I certainly have had insects on plants inside before - mites and aphids principally but not thrip. I hope if I move all my plants out for the summer I can eliminate the buggers. I borrowed someone's wood plant growlight stand this spring - maybe they rode along.

Thank you for your thoughts and input. I have grown garlic for several years now and have never had this problem. I harvest, lay on a wire shelf in the garage (with excellent air circulation) for several weeks with leaves still attached, then clean them up a bit and return them to the shelf and we use them as needed. The shelf is not exposed to any direct sunlight but the garage has bright light due to a row of windows in the garage door. I forget what variety they are since they were grown from bulbs i saved from the previous year's harvest. I will venture a guess that they are organic german red. Yes, the cloves are enormous - almost like a small italian plum or pecan. Thanks again and happy growing!

I have had this plumeria for eight years. The leaves are no longer a brilliant green and healthy looking as they were two months ago. They have rusty brown spots and solid brown areas on the leaves and the leaves are turning yellowish green. The two other plumerias I have on either side are also starting to look the same. They are all in pots on my back porch. I have never had anything like this before. Does anyone know what this is and what I need to do to fix it?

Isn't it sunburn?

Thank you Christopher for responding. I have never had a problem before. I am not sure. It could be, we put them on the pool deck why we painted the patio. The other leaves look different. Could it be an over watering issue?A lot of rain blows in on the porch.

Just wondering if the sunlight reflecting on the water intensified
the brightness, the way it is easier to get a sunburn when you are in a pool with the sunlight reflecting on the water...Anyway, sure looks like the sunburn I have seen on some of my plants I hastily put out in full sun...

Hello! I agree, in the initial inspection of the photo it appears to be burn of some kind. That could be sunlight reflecting and/ or pesticide - especially with 2 applications back to back, hard to say. BUT, what you should be most concerned with are how the new leaves look, more so than the old.

It is natural for your leaves to yellow and fall off, especially the oldest ones. But if you feel it's doing it at an alarming rate, then I would say it could be too much water. (or if you saw the new ones yellowing or falling) I notice you have saucers under your pots too, that will hold excess water you don't want. The soil in the little seedling looks very wet - had you just watered?

Don't be afraid to check your soil, check your roots. Is your plant root bound? Is your soil well draining? What are your temps like right now?

At this point it's hard to say too much or not enough water, but you can find out quickly by checking your soil. Your leaves are a tad drooped , so I would say not enough, and your leaves look really good other then the droop & the burn spots. The temporary move could be a big factor like the others have mentioned. Check them out & let us know & we can go from there!

I got the same black-spots problem. This plumeria was attacked very badly by spider mites last month, was sprayed with Spectracide after trying Neem oil. Then, new leaves came out very healthy. Only a few weeks and leaves started again to yellow and fall. So I got the advice to spray it again, which I did. I also noticed a leaf that had 2 black spots, very small in the beginning, but in a few days they were all over that leaf. I removed and discarded that leaf. This morning, another leaf started to show small black spots. What could it be? Please, I really need some help with this.

Thank you in advance for any input.
