tepid and not too cold, add ice to the water. For optimal conditions,
you should add flower food to the water.Immediately after you have cut the stem, place it in the bucket of water being sure to cover
the whole length of the hydrangea’s stem. Soak the hydrangea’s stem for
4-6 hours or preferably over night prior to using the flowers.
Every 2-3 days you will need to cut the hydrangea’s stems again to ensure the bottom of the stem is not blocked.
If any blooms seem to not be taking up water, you can take a small sewing
needle and pierce a few holes in the stem. This will help the flowers
to absorb water faster.
Do not place them near sunlight or fans.
