Using Floral Foam, Do I need to add water to the vase, or is there enough water from what it soaks up?

They will be used as centerpieces and the flowers need to last for about 8 hours.

The foam absorbs a lot of water itself, but 8 hours ought to be okay for what the foam absorbs.
Reply:You need to soak the floral foam until it is saturated before you use it. Then put it in the container, then arrange the flowers, then top up if necessary.
Reply:Yes, you will need to add water but the kind of flowers will make a difference. I would never leave a centerpiece that long without checking it.
Reply:add a quarter cup, unless directed otherwise on a package.
Reply:you should add water just in case, you never know how fast the water will evaporate!
Reply:I have a vase with floral foam in it and we kept water in it so it wouldn't dry it out. i don't really know if thats what we should do or not, just trying to help.
