Looks dead to me. If a few inches of the tip was still firm you could have cut it and started over but it looks to late for that. I think you have to thow it to the compost pile and try again with another stem. Good luck. |
If you try again, don't water until it has roots to take up the water. |
Plumeria cuttings need to dry off before you plant them. Say the cutting needs to grow sort of a callous for around two weeks. Then it will be ready for planting and keep the soil on the dryer side. |
I am up in Nova Scotia, where particularly right now, it is very cold. I have several Plumeria started from seed, about 8" tall. Several times I have noted distress because of my overwatering. Same with my many Desert Rose plants. Too much water, and they rot. |
Looks like your plant should be in a much larger pot. Maybe 4 x larger. I have lots of Plumarian plants, a couple over 40 years! I had a cutting that didn't look good like that & moved it to less sun and less water and it recovered. The plants do not like Cold. I bring mine inside from end of October & out in May since I live in the SF Bay area. In San Diego you can probably keep outside longer. I agree to not over water and use cactus soil. |
I live in the San Bernardino County area and I have several Pluarian plants one is now over 8ft tall and I have them planted in the ground and I leave them out all year in the spring I give a good dose of fertilizer with a high phosphate level and it has bloomed from middle spring to fall |
