new plumeria leaves turning black

5 years ago

I have 5 plumerias, 3 planted at the same time. one of the three seems to grow leaves rapidly, but then black spots begin to form on the stem of the leaf. the black then spreads and the leaf eventually falls off. I have done searches and can't find anything like my issue. it's not black tip fungus or black sooty mold.

any help is appreciated

thanks

Those plants look young. Are they recently rooted? If so, they need to develop a bigger root system.

Sometimes that is a sign of being too wet.

I only water once a week, same as the others. Could it be anything else, or is there anything I should do?

Others may have a different diagnosis but it appears to be black tip. There are as many ideas on treating it as there are growing methods. If you were in a warmer climate, some good strong sunshine and warmth would help. Are the tips a bit spongey? I used straight lemon juice on a plant last year that just wouldn't heal on its own and it seemed to stop it. You might also try to remove the black portion of the tip and treat with a fungicide. Hopefully someone else will give you other ideas. kb

This is year 4 for my Plumerias. I have two that I have grown side by side from cuttings. This year I have one that is doing well with 3-4 inch healthy leaves. The other has not been able to sustain any leaf growth. The young leaf tips have been turning black and falling off. I do not believe it to be black tip, the growth tips are healthy and green. I did have one slip up about a month or so ago where they were both left out overnight at/just below freezing. I am in central North Carolina.

Some new leaves turn black

This happens every year, and the problem eventually goes away as my plants leaf out. In a couple of weeks all the leaves will look healthy, but I sure would like to know why this happens. I'm in Georgia, and it's been nice and warm (or hot) and they're in a sunny spot, not getting too much water. Any idea what causes this?

how long ago did you get them ... what does your seller say ... are As ok in z9 .. someone will chime in ... were they greenhouse or shade house grown.. and in what zone in regard to sun intensity ... did you properly harden them off to your sun intensity .... sun tolerance is not relevant.. for a newly shipped in plant.. unless it was locally grown .... even a damaged leaf can process sunshine into energy ... i would stop cutting them off ... others will also answer if this is some sort of endemic A problem ...and if there is a chemical solution ... ken

should I not water at all right now? I thought my leaves were long enough.

If it is being rooted then I would hold off on watering and place the plant on heat mat or outside on warm concrete (but not in direct sun if you are in a hot area of the country). The objective is warm and generally dry to promote rooting.

I also have this problem. I planted them 6 months ago, they flourished outside (even got flowers), then were moved inside as the temp. became cooler. I have them now under artificial light (where I first started them 6 months ago), and they are growing but the leaves turn black and fall off after reaching an inch or two in size. I suspect some watering issues, change in light, as well as temp. Aka stress. Just not sure if they are going to make it. Also, I they do need nutrients from time to time, which I have not done. I don't have any answers - just throwing out the things I am considering and still looking for more definitive answers.

Just bought one 4 days ago that was extremely wet & took inside with my others. I think it was too soaked when I bought it. I have 4 others that I have had & they're fine. I think its due to overwatering. Hoping I can save it! Try taking it out of pot carefully with dirt & letting it dry out. I am too- will let you know if mine works👌

Has anyone ever found an actual solution to this? My indoor plumerias are having this happen to them as well, although the stems still seems to be green and solid. Is it because it's gone into dormancy or something? Or overwatering?
