Disinfect knives, tools, and buckets daily. Remember ethylene gas given off by most vegetables is detrimental to flower life.
- How to use wet floral foam bricks in hanging floral installation?
If you are making a hanging floral installation using fresh flowers and foliage, we would recommend using wet floral foam bricks in plastic cages. The cage structure will help hold flowers and foliage more efficiently. In some cases, you may need to wire large stemmed items to the cages. You will then need to calculate the weight of the arrangement (including the bricks) and pay special attention to how you secure this to your ceiling or structure. Some florist often use cable ties.
Depending on the weight, you might need to ask the help of professional install engineers who are used to secure such installations for weddings and events.

We recommend a long blunt blade or knife, similar to our foam cutting knife, for an even and safe cut. You can also use a number of other knives to cut your way through the soft material. No one will see the cut floral foam as it will be covered by your arrangement, so it does not need to be an engineering project.
- How do I place floral foam into my container or ceramic pot?
Place the brick over the top of your container. Cut the brick to be a little larger than the container because you need to push the foam in so it wedges itself in the container and does not move. If your container is round, you may want to shave some of the foam. Similarly, if your container is conical with a smaller base than top, you may have to shave some foam. Don’t throw away your offcuts as you can use these to wedge into any gaps and keep the foam in tight.
