Gerberas stay the best if they stand up to 1.5 cups water, preferably without other types of flowers in a vase.
Fill the vase with a little lukewarm water and a little chlorine. This prevents the gerbera stem from taking on too much fluid. The stem of a gerbera is in fact just a sponge.
A piece of wire or prevents the stem of a gerbera to gerbera 's wilt, but make sure the wires are not against the vase arrive otherwise you get rust in your vase.
