Indoor frangipani wilting/dying

Question

We have been growing a Frangipani plant indoors since May of this year. It was originally just a dry stem we brought home. It budded after a while, much to our delight, but the stem then started to tighten and darken. This has continued to progress over the months and now 3 days ago the leaves have begun to wilt, see photos attached.

A second stem we had, never budded and was rotten from the inside out with maggots when we eventually pulled it up and looked at it. It was in a separate pot. Is there any saving this one or is it effectively dead? Any advice and especially any cure would be great fully received.

Thanks in advance,
Clive

Answer 1

This could be a watering problem, either over- or underwatering depending on whether the soil is drying out enough between waterings. A plant with few leaves will not use very much water and could develop root damage if the roots stay in wet soil too long. Also, an underwatered plant with wilting leaves will perk up after watering, while an overwatered plant will not.

There is a chance that the other plant was killed by a disease. In case that's true, make sure the soil and any plant material from the other plant has been removed from the area and any gardening tools used on the other plant have been sterilized with a 10% bleach solution.
