How to Soak Floral Foam for a Flower Arrangement

Learn how to soak floral foam for a flower arrangement from floral designer Sarah Brysk Cohen in this DIY wedding flowers video from Howcast.


Now I'm going to show you how to work with floral foam.

Floral foam comes in these bricks. And they're dry and very light and they need to be soaked in order to be ready for flowers in an arrangement. So there are always two sides to a brick of floral foam. There's the top, and then the bottom with all of these little holes. And the holes are the way that the water soaks through in the floral foam.

It's really critical that the floral foam is totally soaked before you start working with the flowers. And as you drop it in the water, you want to make sure that you just really drop it. Don't submerge it. Don't force it. Just let it soak up and it will sink as it soaks. And the really key part of working with floral foam, as I said, is getting the foam totally soaked with water. If you push it, submerge it, mess with it at all, there can be dry spots in the center of the foam, and if you had a flower that got placed in that dry spot, that flower would die in the arrangement and we certainly don't want that.

So you can see it's starting to sink as it goes down. And you want to leave the floral foam to soak for at least about 15 or 20 minutes, making sure that it's thoroughly, thoroughly wet.

And that's how you soak floral foam.
