Using Oasis® Wet Floral Foam.

Soaking
Fill a clean tub or container with fresh water and if you wish a measured amount of flower food. Place the floral foam brick (or any portion of it) onto the top of the mixture and allow the foam to float freely down into the water. DO NOT FORCE THE FOAM into the water as this will create air pockets and prohibit the transfer of water from the foam to the flower stem. Please remember that water must be added to your floral foam to replenish supply on a daily basis.

A standard brick of OASIS® Brand Floral Foam can absorb approximately 1.9 litres of water in about 50 seconds and gives the flowers water when needed.

Storing 
If kept in good conditions OASIS® Floral Foam will not deteriorate with age. Avoid extreme heat and humidity as this can, in some cases, reduce water retention properties.
