Hanging baskets - in need of a prune?

The the first time ever I made up four hanging baskets this year. The plants in them are petunias and pansies.

All of the plants look pretty healthy but the ones planted in the side holes are drooping badly - they used to grow quite upright but now I guess their weight is dragging them down.

Most affected are the pansies, but the petunias are also affected to a lesser degree.

To get them to grow upright again is it just a case of heavily pruning them?

 

Maybe those are meant to cascade
When you water do you do so generously?
can you post a picture?

 

Unfortunately they are cascading too much. They were fine when there wasn't as much growth but now they are weighing themselves down. Yes, I water when required. Sorry, no photo yet.

 

Ah yes, but mine aren't the trailing variety - at least, I recall that they are "spreaders". As for the pansies, they really do look a mess. Perhaps I should have put more trailing plants in the very top of the baskets to cover up the gaps in the sides.

Ah well, live and learn.
