Can I make my snapdragons flower again?

[Weepingwillows12]

I had a few snapdragons that survived the winter and due to the lovely weather have been flowering since April. They are pretty much done now but I was wondering if I cut them right back whether they might grow and flower again for July? Has anyone done this.

Just cut off the spent flowers, they do the rest.

The whole stalk or the individual heads?

Cut the stalk below where the dead flowers are, just above the first side shoots coming from the stem. The side shoots will grow and flower. If there are no side shoots, cut the stem below the dead flowers.

Thank you
