I live in zone 9.
If they have the same soil, water, and light requirements, and the container is large enough to accommodate both rootballs.

Many of my star jasmine leaves are showing the browning in the attached photo. What do I need to do? Thank you.
Unfortunately, your photo did not come through. I am unable to assess the damage.
If there has been rain in the area, or the soil has stayed too moist, then I could suspect infection. Fungicides will be in order, here. This article will help:
..my son in law has an abysmal display...his plant is more like a bush and does not send out any runners to train upwards... The photo with a white circle round is my son in laws and it is sharing an arch with a clematis that was planted to cover the bare top...the second photo is my plant lovely specimen
Is it possible he accidentally got the bush variety?
Here are some care articles he can check against what he provides.
This can be normal. I don't see any signs of disease, but I do see signs of a need for feeding.

Hi there, I have a Star Jasmine for about 3 years now. The year before last, all the leaves on it died so I cut it back and it produced lovely green leaves and flowered for the summer. However, last year the leaves turned red early in the year and stayed red for the whole year and it didn't flower at all last summer. The leaves are still red so I want to know what I can do, if anything, to get the leaves back to green and for it to flower again this summer. It's in a very large pot with a climbing frame. Any help would be really appreciated. Thank you.
The consensus on red leaves seems to be overwatering. If you don't think you are watering too often it may be the pot is too large, which can cause the plant to absorb too much moisture. I am including a link to care instructions so you can see if all its cultural needs are being met, i.e., watering, pruning, fertilizing.
My jasmine has been sitting in a 7-gallon pot since last spring...it has not grown since! It will develop new leaves but then they dry up and die!!! Do I need to downsize the pot, put plastic jugs in the bottom, give it to someone who knows what the heck they're doing, and has a true green thumb?? I am soooo waiting to see the flowers and smell that scent...PLEASE HELP! Thank you Karen
That is quite a bit of extra space, and if the container does not allow all extra water to drain out, then this can cause fungal/bacterial issues. I do see a saucer, which is a good sign. Never let water sit in the saucer. It would be a good idea to make sure that the soil dries, thoroughly, down to about 3 inches before watering again.
These plants grow, extremely, slowly. Any attempts to speed the growth up may hinder the process. It is very important to maintain proper soil moisture, though.
Here are a couple of articles that will help:
The jasmine was one of two left (but well covered) in the balcony during the winter...one of them has remained healthy but the other is shedding leaves of a yellow colours. They were both only lightly watered but now are given water once a week. What to do?
It may have gotten more cold exposure than the other, depending on how the containers were sitting. Remove the yellow leaves, and follow these care instructions below. Also check the leaves for any pests that might be hiding. It also wouldn't hurt to spray it with Neem oil, which helps fungal problems as well as pests.
