How do I keep my plan growing?
I am having trouble growing a Calathea,I have indoor lights on 24/7,a heater that the temperture around 60 degree. The leaves rool up,brown spots start appearing on the leaf.
Answer
Calatheas prefer indiret light, high humidity and moist soil in spring/summer. The plant requires less watering in the winter. It is not necessary to use lights and a heater. The plant does prefer warmth but indoor heat should be enough. Fertilize the plant regularly.
