This plant wants water when the top of the soil is dry, but you can still feel moisture just below the surface. This plant will often fall into a once-a-week watering cycle, but remember that your watering should be based on the moisture left in the soil, which will depend partly on the moisture in the room and the weather outside. The soil 'surface' goes a bit deeper for larger pots; for example, a plant in a 14-inch diameter pot should dry out a couple of inches deep before you water it, while a plant in a 4-inch pot will only want to dry out in the top half inch or so of soil. | |

Notas de cultivo
Calathea are dramatic foliage plants that fill out from the base over time. Many have dark undersides to the leaves. This can be a dramatic contrast from day to night and against light walls or fixtures when placed at an elevated position.
It is natural for older leaves to dry up and remain at the base of plants. If they do not come off with a light tug, they are easily pruned off to keep your plant looking tidy. You can prune your lower leaves once they begin to brown, without worrying about hurting the plant.
Brown crispy tipping is common on this plant when it is grown in direct sun, or too dry of a room. Try moving it to a bright spot or a bathroom or kitchen near a sink, if you see this.
Interés especial
During the day leaves spread out, showing off graphic patterns on their tops. These plants evolved their characteristic patterns to convince bugs and other predators that they've already been eaten and only the leaf skeleton remains. Amazingly, at night the leaves fold upwards and inwards. The undersides are dark, helping to cloak the plant from any predators. This upward nightly posture gives this plant its common name: the prayer plant.
Most houseplants are poisonous to cats and dogs, but calathea are not!
