In an experiment, Dr  Farouk studied houseplants that had flourished for years  Over a three-day period he spoke to the plants encouragingly  He then transplanted them outside into a garden and stopped talking to them  Although he continued watering and fertilizing the plants, they soon wilted  When they had not recovered after two days, Dr
Farouk became so concerned that he started talking to them every hour; the next day they began to recover
Plants always need at least two days to adjust to transplantation.
