Light-Colored Plastic Pots Affect Poinsettia Root System

Subject:

Light-Colored Plastic Pots Affect Poinsettia Root System

Abstract:

While investigating a chlorotic foliage condition in 'Annette Hegg' poinsettias at a Half Moon Bay nursery, researchers in California made a surprising observation. Plants growing in white and light-green plastic pots had a poor, greenish-colored root system visible on the outside of the soil ball. Plants growing in a similar location in dark-green plastic pots had excellent white root systems. Chlorotic foliage was most pronounced on plants growing in the white and light pots. Symptoms were minimal on plants in dark-green containers.
