Sweet pea support

[annie8]

Saw these for sale in Waitrose. Wasn’t planning to buy I was just surprised at how densely planted the sweet peas were and that they were planted to grow up in the inside of the canes. Haven’t grown sweet peas before but had been planning to put them outside the canes and much fewer per structure. Can anyone advise?

Depends on how you are fixed for outside space really - in the ideal world a nice large bed, ready dug and liberally manured to plant them in - failing that then the biggest containers you can manage to find and fit in the available space - 20L paint buckets for example with holes drilled in for drainage.

Good rich compost, but free draining.

Your'e quite right that the plants are too close together - when everything else is ready and you have somewhere to put them, knock the plants out of their current containers and dump the bottom half in a bucket of water - carefully separate one or two plants at a time, putting them back in the water to keep the roots damp - when you've finished disentangling the root-ball, plant them up and give a good watering - repeat for the other containers - sit back and have a cup of tea and a pat ion the back.

Don't forget to snip off all flowers when they come out even if you throw them away- if you stop picking, the plants stop flowering.

It looks like each container has ten canes & it looks like there’s ten plants,sweet peas cling on to each other & can get in a tangle but you can guide them each up a cane early on,twirling it around the cane. I think it looks alright,the roots will find a space,I had two sweet peas flowering in 3” pots once they looked good on a table edge dangling over.

If you pinch out the growing tip of each plant you will get many shoots.
I would think it will be difficult to train them up the canes..
If you have the space take them out and plant individually.
I grow mine up green chicken wire.
