Jasmine - 2nd and 3rd year tips

Hi,

I planted a Jasmine in a smallish planter (approx 60cm diameter, hexagonal) in Spring 2012. After a strong first year of growth and flowering it has continued to grow strongly this year but has produced very few flowers at all. Is this a natural part of its growth cycle or am I doing something wrong?
It gets full sun from first light to around 2pm-ish, shade thereafter. I mulched it with fresh compost and lightly pruned back dead growth in Spring this year. I have watered it regularly but not fed it much. It is currently around 2m high, reaching the top of the supporting trellis, and I am hoping to continue to train it over the top of a gate and along another fence.
Any tips on how to get a better showing next year much appreciated. I'm concerned the planter may be too small but transferring it is not a job I like the idea of much unless absolutely necessary.

Cheers

 

60cm diameter is a HUGE planter, why do you say it is smallish?

Huge, really?! If you say so.
I have plenty of bigger ones in my garden, and in comparison to the height and vigour of the plant it doesn't seem very large to me. But if planter size is not the problem I'm taking that as good news.
Would welcome any suggestions as to what I can do to inspire more fragrant blooming next summer

 

Well, this has got me curious now, are you sure that the pot is 60cm diameter!!

Hi

is it the white form ?? Jasmin official ?.

The trick with this is to prune as soon as the flowers have fallen and to train them vertically so the sap slows down to help induce flowers , the ones I have on the trellis only flower at the top on the new growth so I think this is what's happening with yours

Early flower flushes develop on the previous year’s growth, but later flushes develop on the tips of the current year’s growth. Pruning after flowering gives the new growth time to mature and flower early next season.


so is the pot 23 inches by 23 ? , as long as you keep up on daily watering all through the summer and a high potash feed ie tomato food it should flower I would steer away from anything that is high in nitrogen as this will produce lush growth and very little flowers

Hope this helps

If it is, it's not what I would call a "smallish planter"

Had another look and to be fair it's prob more like 40cm diameter.

 

This is very helpful, thanks. I'll use more feed and prune after flowering next year (although tbh this year there was v little flowering to prune after, so not sure what to do if it's the same next year?!)

How much should I prune back each stem after it has flowered would you say?

Thanks for your help
