Hi Richard
Your confederate jasmine should recover as long as the roots don’t get frost damage. Depending on the severity of cold damage, the vines may die back but should regrow from the roots. In less severe cases, the vine will drop its leaves but can send out new growth from the leaf nodes in spring. One thing you can do right now, is to add a few inches of mulch around the base of the plant to add some insulation to the roots. If possible, cover the vines with a blanket during this cold spell which will help minimize cold damage.

Hi Kevin
The leaves will turn red in winter. By being exposed to freezing temperatures, your confederate jasmine may eventually drop all its leaves but the roots may survive. So don’t give up, the vines can resprout in spring. If not trim back any dead vines up to healthy growth.
Add some mulch (2″) around the roots to keep them insulated during the coldest part of winter.

Yellow leaves
The plant is in the original black plastic pot and I plan to re-pot it after the plant stop flowering. My balcony is south facing and it does not get much sun (only a few hours in the afternoon).

The flowers started to die now and I’ve noticed a few yellow leaves (it was all green a few weeks ago).

Can you tell me how to fix the yellow leaves, it is not enough water or is it too much? (I live in Sydney and it’s approaching summer).

HI BT
If the old leaves are turning yellow, then you vine may need a fertilizer(N). It’s been working so hard to give you flowers that it most likely needs more nutrients to keep going. Give it a balanced formula (10-10-10) follow label directions usually every 2 weeks. If the plant has been relocated in an area with less light, it will also shed some of its leaves. In the summer season, make sure your jasmine gets enough water and that it drains out from the bottom of the pot.

Hi Fran
The plant is responding to some kind of stress. Are the leaves turning yellow, red? Do you have an insect infestation? Has it been exposed to cold weather, too much water or not enough?

Hi Nancy
Jasmine polyanthum is hardy in zone 9-10. It should tolerate the warmer temperatures. It does need cool night temperaturesfor 4-6 weeks in winter (33-55F) in order to set buds to bloom.

Vines that have been acclimated to grow in one direction don’t always take well to having their orientation changed. Leaves that may have been in shade are now in higher light exposure and are wilting. Another idea is that the vines may have been damaged when being tied to the trellis.

Hi
I cannot give you a specific timing for watering. If the temperatures are hot and there’s no rain then you may have to water every day. It also depends on the type of soil, clay soil will hold moisture longer whereas sandy soil will dry out much faster. Stick your finger into the soil and see how dry it is. If the top 2 inches are dry, water it well and then wait a few days to recheck the soil. Your plant will also tell you if it needs water.

HI Stacy
Jasmine like other tropical plants such as mandevilla, hate to the dry indoor air. Low light, low humidity and cooler temperatures will make it sulk and drop its leaves. Cut the plant back in spring up to 1/3 and as long as the main stems are viable (green) it should recover.

Hi Dawn
Look at the stems (vine) and leaves, see if there are any small raised spots or bumps on the surface. If so you have scale.
