How many Star Jasmine to act as a screen?

[united4ever]

See pic. I have one star jasmine planted in spring behind the overgrown Acer (Acer to be pruned back). Trying to cover the area in red circle.

Do you think I will need a second star jasmine to get the busyness and coverage.?

I don't want to wait several years for it to grow and then realise I should have planted another. Similarly, I don't want to have more than I need and it get too full/busy.

If you think I should get another is it ok to plant in soil in November?

Container-grown plants are fine to put in the ground as long as the soil is not either waterlogged or frozen.

I'm not sure how vigorous they are, so maybe two of them? Better to have too much that wait years for it to be too little.

Thanks. Ordered a 7ft one from Primrose today. The first one I got was just a cane one about 1 meter. Should have bought a bigger one with hindsight.

In my experience Jasmine takes a year or so to get going but once it does get going it’s unstoppable. Your two will easily fill that space given a bit of time - my one gets chopped with hedge shears once a year now and still outgrows its allotted space by miles.

I would only plant one in that space as they grow eventually up to 5-10 metres tall and wide. That said, they are slow growers so if you are in a hurry, maybe grow a clematis or a regular jasmine. Alternatively, you could plant annual climbers like morning glory for a few years (they're easy from seed) to cover the space whilst you wait for the star jasmine to grow.

Like @Purplewithred I find once they get going they're pretty relentless! I had an established one in my previous garden that I was constantly hacking back-. It was covering a fence of a similar size to yours OP. I've put one in my new garden this year and was expecting it to romp away like crazy as my previous one did and its first year its done barely anything! I wish I'd put a larger plant in TBH. I expect once its had a year or two to settle in it'll grow like crazy like my previous one did.
