If the pot you moved it into is much larger than the pot it came from - it might actually be too wet and rotting off at the roots.

If the terracotta pot has only a small drainage hole (or none) then water could be sitting at the bottom of the pot for too long.

If your potting mix has a lot of peat in it - that can be unsuitable for many plants which prefer good drainage and air spaces around their roots.

You might want to downsize your pot to a plastic one that allows no more than an inch all round from the size of the original one. You could use your terracotta one as a cache-pot with some pebbles in the bottom for the real pot to rest on. That would actually keep the roots cool, too.

Move it on before the roots start circling the pot or growing out the bottom. Next move could be early spring but be ultra-careful about watering and temperature changes then. It can be so easy to overwater then be caught by a cool spell and lose a lot of roots (or even plants) to rotting off.

As the plant is still quite small and you will, hopefully, be upsizing the pots for a while to come then a simple arrangement of canes might be easier to cope with than anything like a trellis.

thank you for your response. I think I got to excited over nothing, my Italian jasmine is growing very well now. It is growing new shoots all along the branch and the tips are growing new buds. I am grateful for the response from vetivert8. It is doing great after all.
Ciao, Maggie
