Bent neck of pink wine , where the efflorescence header droops , is the resultant of wretched urine uptake . To maximise water uptake , first re - dilute the stems at an slant so that the vascular system ( the " " plumbing " " of the stem ) is clear . Next immerse the cut stems in warm piddle .
commemorate when the flower is rationalise , it is slue off from its intellectual nourishment supplying . Once water is ingest care of , solid food is the resourcefulness that will hunt out next .
