Each stem in your bouquet has an internal wire which is coated in plastic. Depending on the stem, this wire can be fairly lightweight or pretty thick. Thicker wires can be slighter harder to cut.
1. Measure the height of your vase.
2. Take the vase measurement and measure from the bottom of the flowers and foliage area towards the bottom of the stem.
3. Mark the measurement and cut any remaining stem off.
4. If in doubt, leave the stems a little longer. You can always trim them again.
To cut the stems, we recommend using strong wire cutters. If you don't have any of these to hand use pliers or scissors to score the plastic. Then bend them one way, then the other, which will weaken the wire to the point it breaks cleanly.
