Growing sweet peas in toilet roll tubes

[P0ppy8557]

Yay/Nay

Do you plant them out in the tube and do they rot down?

I would. The roots will grow through the sides of the tube (if not the ends) and the tubes should rot down eventually.

Yes, it will work well. The tubes just turn to mush once you plant them.

Yes. They hate their roots disturbing. Plant deeply; make sure all the cardboard is below soil level.

Be careful with watering though.
I had to chuck my sweet peas away as the cardboard tubes became very soggy and unravelled.

Yay.

Everyone here knows to save toilet roll inners for months until I declare I have enough for the next sowing season. Sweet peas are one of the things that do especially well in them.

I used to do this with beans - worked really well and massively improved my heavy clay soil along the way.

I had problems with the tubes unravelling. I've saved the tall cartons that single cream, buttermilk and the like come in. Been using the same ones for a few years now. Just poke some holes in the bottom. The seedlings turn out of them very easily and it's nice to reuse something I'd bought anyway.

Yes. I planted seeds in toilet tubes a year ago in the autumn. Then planted the entire plant out in the tubes still in spring, they did really well. When I pulled them up last autumn there was no sign of the tubes. I’m not growing sweet peas this year as I got tired of cutting the flowers every morning for the house, so I’m giving them a rest this year.
