Calathea louisae aka goeppertia louisae is a striped light and dark green house plant that grows naturally in Brazil.
No direct sunlight, but give it as much indirect sunlight you can. It will be ok in medium light, but will grow best in brighter light. I would keep them in an East- or West- facing window.
How Often To Water Calathea Louisae
You want to keep the soil moist but not wet. So check the soil twice a week and water the plant if the top third of the soil is dry.
They can be prone to fungal infections so try not to wet the leaves.
Tip: make sure you tip out all excess water so the plant does not get water logged. Make sure you just filtered water. I use a brita water filter and let it stand over night, they hate hard water and can be really fussy about it.
Feed them with a balanced plant feed every 3 or 4 weeks in spring and summer. Always be cautious when diluting your fertilizer and over-dilute so you don’t give the plant a fertilizer burn.
They like a really light, airy soil, that is rich, good quality and drains well. Add perlite to a good potting compost if you like, make sure it has about 20% perlite to 80% potting compost.
When to Repot Calathea Louisae
Check the roots each year to see if they are getting crowded and move the plant to a bigger pot if needed. A good time to check is early spring so you know they have enough space to grow over the warmer months.
60-70% is good for them, they really thrive in higher humidity levels, and they can dry out and crisp up if not given enough. They like high humidity, but make sure there is circulating air, to avoid fungal issues.
Aim for 18-28°C (64-82°F) during the daytime, and try to keep them above 10°C (50°F) at night.
How to Propagate Calathea Louisae
Propagate them by division at the base when they are big enough. When they start to mature they can spread out, at which point you can divide them. Take the plant out of its pot and shake off as much soil as possible. Then divide off the smaller plants, be as careful as you can to avoid damage to the stems or root system. Then you can plant each plant in it’s own pot and put the main plant back in its original pot.
