Sweet Peas on Obelisk

Can you grow sweet peas on an obelisk?

Yes, you can grow sweet peas on an obelisk. Sweet peas need something to grow up and an obelisk provides all the support they need.

Any obelisk will work just fine but be aware that you will probably need to tie your sweet peas in at first. Use twine or a twist tie to attach them to the structure.

Just make sure that you do not fasten the ties tight as this could damage the plant. You can leave it pretty loose, it just needs to hold the sweet pea in roughly the right place.

Over time the plant will do the rest and attach itself to the obelisk using its tendrils. If you are thinking of other ways to support your sweet peas then have a look at my sweet pea support ideas. Or read my post about growing sweet peas on a trellis.
