Begin by unwrapping your wet foam and placing it in a bowl of cool water. It will start to absorb all of the water just like sponge. Leave it in the bowl until it is fully saturated.
Remove the foam and press it into your container of choice so that it is nice and secure. If it is too large, you can use your knife to slice away any extra.
Trim the ends of your greenery stems so they can best absorb the water. Press them one at a time into the foam. Start by placing your longer, taller stems in the center, and fill around them with shorter stems. Finish the piece by adding your tiniest stems wherever you see gaps.
Your fresh greenery centerpiece should stay fresh for a week or more. You can add water after a few days if you wish to rehydrate the foam, but it should continue to feed the greenery just fine.
