Ep. 8. Watering potted poinsettias

Potted plants are arguably overwatered in the greenhouse and nursery industry. Over-watering can be considered a waste of water, results in leaching of pesticides and fertilizers, and can promote plant pathogens. In this episode, we discuss a study that uses various sensors to assess plant stress to determine how much watering can be reduced before the plant is 'too stressed'.
