You want to remove the centre of the growing tip just above a set of leaves. I like to leave two pairs of leaves but you can just leave one.

Grab the tip of the sweet pea between your finger and thumb and pinch it out. You can use the nail on your thumb as a blade to slice the tip off, it should come away fairly easily. And that is it, you are done, well for this sweet pea at least, plenty more where that came from!

Above you can see the sweet pea with its main centre stem pinched out, this would encourage the growth of new side shoots.

Why pinch out sweet peas?

We pinch out sweet peas to encourage them to grow bushier rather than taller. Sweet peas, if left untended, will grow tall but not particularly wide.

When forced to grow bushier by pinching out the tip they actually produce a lot more flowers, which at the end of the day is what we are after!

Each of the side shoots that the plant goes onto develop, because we pinched out the main stem, will be a flowering stem. So it is easy to see how we can end up with many more blooms by doing this.

You can actually do this with regular peas, this will lead to an increased harvest over letting them grow naturally.

Do you pinch out dwarf sweet peas?

Yes, dwarf sweet peas should still be pinched out just like regular sweet peas. Even though dwarf sweet peas are bushier by nature pinching them out to encourage even more side growth is still beneficial.
