Large calla may come with a plastic sleeve. Remove this and cut the stem
with a sharp knife before placing in water at least half way up the
stem to help hydrate completely. This could be up to six hours for
complete hydration. Mini calla come in bunches. Place only 1-2 inches of
water for the mini calla.
To make your calla lilies last as long as possible, avoid touching the
blooms and handle them as little as possible. Keep them in a cool place,
out of direct sunlight and away from fans or drafts.
