BACKGROUND
I have a jasmin plant (jasminum sambac).
- Up until about a month ago it was full of green leaves, and had scented white flowers blooming
- About a month ago many of its leaves started yellowing and drying out, and now there aren't that many left
- I cut the dry yellow leaves off, thinking it was stress related, and hoping the plant would be better in time
INFO
- Light conditions: plenty of sun
- Water conditions: soil is moist when I put my finger in. Looks like it retains water properly, almost like it's "not drinking" the water. It's currently lightly watered once a week (to avoid root rot)
I also thought about water purity issues (see this question) or soil volume might not suffice (see this question), but all the other plants enjoy the same water and they're fine, and the soil volume is about 5 times bigger than the pot it initially grew to be this size in.
ISSUE
Now the last leaves also started drying out, and the stems feel like they're drying out too.
How can I save it before it's too late?
