Sweet peas or clematis in pots


I have lots of sweet peas ready to go out and two celmatis. I really fancy something like this growing up beside the patio doors - does anyone know whether either of these would be ok in a pot against a south facing wall? If so, any ideas about pot size - I have a 30 cm diameter plant pot...

I have read that sweet peas like a bit of depth and clematis like cool roots, so not sure about this. I'd risk it for a biscuit with a couple of sweetpeas, but not my clematis!

Thanks image

    Sweet Peas will be perfectly fine in a south facing pot. I have done this again this year.

    As for Clematis, this will also be fine BUT I would emphasise to cover the roots with either a good layer of mulch (Bark chippings are perfect) or Stones will help keep the roots cool.

  • Oh thanks - I've got tonnes of stones!

    What sort of size pot do you put your seet peas in? No idea how big they get at all to be honest.

    Sweet Peas will grow to about 8 feet or more if they have the space to climb.

    I would recommend a largish pot for the sweet peas so they can maximise they're potential.

  • I use the large double handled pots that trees are grown in ,in GCs, with a wigwam of canes. Very important to water very regularly or will brown off. Keep feeding with tomorite

    They won't stay looking good for long Louise, I'd move them as soon as you can. Just be as gentle as you can, you may not be able to separate the roots too much at this stage but they will do better out of those small pots. You could put them into a big container if you have one, I grow some in a large pot up a wigwam every year and they do well. I feed them a couple of times a week and add bfb or growmore to the mp compost I grow them in.

    The best ones for me grow in the ground so if you have that option I'd got of it, perhaps do 1 load of plants in the ground and the other in a big container. Good luck, they're wonderful plants producing smashing highly scented blooms depending on the type, I've been growing them for many years.

    Sweet peas are reaching up fast for the sun on my north-facing fence, they'll grow even faster up your wall image The bigger the pots the better.

     I also have a concrete s-facing patio 2 clematis in pots, the viticella looks spectacular every year, whereas the montana - deemed to grow anywhere - clearly needs planting out as it looks poorly, even in a large pot. I will use that tip on stones tho - thanks Mattbeer87
