What a great forum is this. I hope you understand my not so good english.

I bought a 3 year old plumeria last summer but it didn't flower. It has 3 branches, like a fork. It is overwintering in a greenhouse by temperatures between 40-50 degrees.

Now there is since 1 week, at 2 branches, a softy area, about 1 inch below the tip. The tip is still green and glossy.
The color of the softy area is a little grey and is about 1 inch long, all around the branche. I also noticed that the spots, where the leaves were atached to the branche, are black in this area.

Is this cool damage and must i cut it now, or shall i wait till the temperatures rises again?

Thanks, emenbritt

40 degrees is a bit low for plumerias if they remain that cool for a long time. Is the greenhouse warmer during the day?

Have they been getting some moisture? There are many other factors. I had one that got a weird spot about 4 inches down from the tip, but it eventually dried up and is OK. I think it burned from being too close to a light source but not sure.

Thanks for the info.

I have put the plummie in our loft now. There is the temperature around 62 F day and night. The plummie still have a few (brown) leaves.

I sticked a pin in and there was nothing coming out. I watch it carefully the next days.
