Hi All, new here, first post, I have a Plumeria that i have had for 1 1/2 years, grown from seed, up until the last week it has been healthy, new leaves and no markings on the leaves what so ever, now it looks like this, mottled leaves, curled, some evidence of, well tiny snail trails, no oozing anywhere and also on a couple of leaves some black holes are developing. I am worried it is the FrMV, quarantined now but afraid it may have spread to my 5 cutting currently rooting but no leaves yet. I am praying it is just fungi as no signs of infestation. Sad

Where are my plants kept you may ask considering i live in Sweden, I have a grow room ( for winter time ) constant temp of 25c ( 77F ) humidity around 40 % with adequate and specific plant lighting and ventilation. Watering is closely monitored with a moisture meter, last feeding was about 1 month ago with a slow release fertilizer.

Hoping someone can tell me what i may be facing.

From what little I could find on the web that virus spreads by mechanical transmission, not a vector nor did I see any mention of seed transmission. How are thinking it may have acquired a virus? I don't know much about plumeria but have you checked carefully for sucking insects like leafhoppers, thrips etc?

Hi and thanks for your reply, thats the thing, i also checked on the net for the different diseases afflicting Plumiera, fungal infections looked like the issue i have but then so did the FrMV. I have checked the leaves and no sign of infestation, no webs, nothing crawling or leaving eggs. The plant was sprayed a few days ago as some other plants in the house, not in the grow room had green fly, affecting my geraniums mostly..

Did it have the problem before you sprayed it? If not, a reaction to the spray could be a possibility. The curling leaf edges made me think of sucking insects but if there's nothing there it can't be that unless it's leaving the plant for some of the time. For it to be a virus it would have had to come in contact with another infected plant. Presumably that's not likely?

Hi Steve, if you haven't found any insect and the leaves were like this before spraying, it may be the reaction to the fertilizer as well. And how do you fertilize it? Do you water it first,wait for a while and then fertilize?

To be honest,I'm not sure if it's the virus or the fungus or maybe just a reaction to overwater and fertilizer. But I would check the roots, maybe repot, and minimize the watering. Plumeria can be without water for a longer period.

No worries about the tiny white spots. I used to have them on some of mine as well and the plants were doing just well... Blooming too.

BTW ... winter is dormant period, it's good for Plumerias to rest for a few monts. That means they're without leaves, watered occasionally (once a month or so), not fertilized, and in the room with temperature around 15 degrees.

One more thing came to my mind 😉 ... Fertilizers with too much of phosphorus (guess I didn't write it correctly) such as with 10:50:10 NPK, make the leaves to look a bit unhealthy... They don't have the "shine" or don't have nice dark green color.
