When translating this into a room you should place the plant within 1.5m (5ft) of a north, east or west-facing window.

Watering: The lancifolia should be watered around once per week but you should always first check if the plant actually needs it. The top inch (2.4cm) of soil should be dry before watering, which you can check by using your finger. Alternatively, to make things easier and more accurate you can get a moisture meter, which will tell you when the soil is wet or dry.

Ailments: Most Calatheas including the lancifolia are prone to some pests with the most common being spider mites. Spider mites are very small and are very difficult to see, in fact, it’s more likely you’ll see the small thing webbing or the damage they leave behind. You can get specialist sprays to rid the bugs but a drop of dish soap and water in a spray bottle can work just as well. Spray the plant until dripping every three days, be sure to keep going for an additional day even if it looks like they are gone.
If you spot the edges of the leaves browning then this is likely a sign of the environment being too dry and you’ll need to increase humidity. If you start to notice that the leaf patterns aren’t as vivid as they once were then this is probably down to too much light.
