Wallflowers to Sweet peas

AsarumAsarum East AngliaPosts: 567
I have some wallflowers in a large container which I want to replace eventually with some Sweet peas. The wallflowers have only just come into flower while the sweet peas are in 5cm pots, about 10-12 to a pot. Should I pot on the sweet peas individually, and when do you think the wallflowers will be over? I’m new to sweet pea growing.

    Hi Asarum - yes, you'll need to split the peas up as they won't have enough nutrients. Ideally - a pot that size would only take one - or two seeds at most, and then you would plant them out or into a bigger pot. They like a deep root run, so it's better to plant them in a reasonable size of pot from the start, or use the specially made root trainers. I normally put three in a 3 or 4 inch pot if I start them off earlier in the season, and then plant out the entire potful in their final place once conditions are right.
    If you can separate now before they get too big, they should be ok - or most of them will. Grow them on until they're a decent size before you get them in their permanent spot.

    I think you'll need to find somewhere else for them though - the wallflowers will continue for a while, and there would be too much competition if you plant sweet peas in with them. They need lots of food and water. If it's a decorative pot, you could always plant the sweet peas into a plastic pot or container which will fit inside that one. When you remove the wallflowers, you can simply drop the sweet pea pot inside it.   :)

    Thank you for your thoughts Fairygirl. I thought I would have to wait for the wallflowers to go over. As there is no other place for them to go maybe I could pot them up, 2 per tall 10cm wide pots and cosset them, with support until they can go in the main container.  The pots are the ones they usually grow Clematis in.

    I grow most of mine in large pots anyway, and they do well. I put around eight to ten in big 15 to 18 inch wide pots in various places in the garden or on hard surfaces.
    I think you'd be best to pot them into smaller pots initially - two in a regular three or four inch pot - then move them on to your clematis ones once they're bigger and sturdy  enough. They'll be a bit 'lost' if they go from being split up straight into something that size. A small cane for each one might be a good idea too, as you won't be able to disentangle them easily  to go in the big pot. You can then attach that to a full size cane.  :)
