Thank you both for the information and advice. The plants were in individual pots and the pots placed in a larger window display planter which had gravel in the bottom. The roots had grown through the pots and into the gravel display planter. The plants are in a warm room on the window sill and it also has a dehumidifier running so the humidity is kept at a set level. How long would you suggest to let them dry before replanting? They were soaked last night and today feel almost dry. Is the idea behind not watering straight away to allow the roots to recover and grow before they get soaked again? Many thanks.
