Calathea Grandifolia Care
Like many tropical indoor plants, your Calathea Grandifolia prefers a spot with ample humidity. Brown edges on the leaves indicate the air is too dry. Mist the leaves twice per week with room temperature water.
Like many plants, the Calathea Grandifolia enjoys bright light without direct sunlight. North, east or west facing rooms are suitable.
A peat based potting mix is required. 2 parts peat and 1 part perlite is one mixture that will be fine.
Your Calathea Grandifolia prefers average room temperatures from 60-80 degrees. They are sensitive to cold drafts and blowing heat during the winter months, so keep them away from windows and heaters for best results.
Maintain a regular watering schedule and keep your Calathea Grandifolia moist, but not wet or soggy. This is not a drought-tolerant plant, but it is relatively forgiving if you forget to water it from time to time. Extended periods of dryness can result in brown leaf tips or edges.
Use a general houseplant fertilizer every month during the spring and summer. No fertilizer is necessary in the winter when plant growth naturally slows.
These are propagated using the division method. Divide clumps of leaf stalks and leaves with roots when it's repotting time. To encourage new growth cover the plant and pot with polythene then once new growth appears remove the polythene.
