Star Jasmine overgrown when to prune?

Hi Lee, I’ve just watched your latest useful video about winter jobs and think I’ve made a big mistake by chopping away at a very overgrown Star Jasmine climber!  As it’s an evergreen I now realise I should have waited until spring! Do you think it will be ok?

I’ve not chopped it right back and have kept alot of green on it but it still looks quite straggly. I thought I’d wait until spring them maybe cut it back again. Any advice please. I’ve also got a chocolate vine that has gone crazy with tons of dead wood underneath the green and would like to have a go at that, but will wait until the Spring for that one.

thanks, Helen

Hi Helen,

Thanks for your question.

Ideally, you would only prune an evergreen Jasmine (Trachelospermum jasminoides) at the earliest in spring. The best time would be to prune it late summer once it has flowered to prevent losing flowering the following year.

However, it won't harm the plant but it may mean that you get reduced flowering this year. I'd give it a good mulch in spring with some peat free compost to help it along. You may also want to follow my easy pruning guide here to show you how to prune properly.

Pruning a chocolate vine / Akebia quinata

Choclate vines (Akebia quinata) are semi-evergreen vigorous climbing shrubs. They flower in spring and provide berries/fruit in Autumn. The best time to prune them is in spring once they have flowered. They will cope with a hard prune then as they are really tough and fast-growing so that would be the best time Helen.

There's also more help for other readers in watching my winter garden maintenance guide below.

Happy gardening!

Hello Lee,

I thought I tag along onto the conversation as I've a similar question.

I want to attach posts for a pergola to my existing post and rail fence and would ideally like to the retrain my jasmine up the pergola. My question is will it harm it to unwrap it and then rewrap it around the new post, or should I just cut it right back after it's flowered and then it will regrow? I'm loathe to lose all the growth its got as its taken about 4 years for it to get this big, and it's only really started to get going this year. I don't want to accidentally kill it!

Many thanks for all your wonderful videos on YT, so inspiring and helpful. 

Kind regards

Emma

Hi Emma,

Many thanks for the kind words about my YouTube Gardening Guides.

The Jasmin you have is evergreen Jasmin (Jasminoides trachlepspurmum), not the faster growing deciduous type. Hard pruning should be avoided as they are super slow to grow. 

It won't harm it to unwarp it and retrain it though, we do it all the time on Garden Rescue to peoples badly neglected climbers. Give it a good mulch once you've fiddled with it as a slow-release feed. Otherwise it won't need much love or attention, just full sun!

Happy gardening!
