Care For Your Calathea Medallion They grow best where they get medium to bright, indirect light. Being the tropical plants that they are, Calatheas should be watered regularly so that the soil is always at least lightly moist but never dry.

While some might appreciate being misted, take care not to mist them directly on the top of the leaves (or have moisture fall into the tightly raveled straws the new leaves make). Spray from the bottom up, and higher overall humidity is preferred over misting.
If your Calathea is not closing at night, it is due to not getting a complete dark condition at night. An artificial source of light is continuously penetrating the leaves of your plant and hampering its diurnal cycle.
Limp or rotting stems or drooping leaves could be caused by overwatering, although more likely by cold temperatures or exposure to drafts. If the plant remains in these conditions the damage will not be reversible so make sure to move the plant to a warmer spot or away from the cold draft immediately.
Calathea plants like to be on the moist side, but they do NOT like to dry out completely. A good rule of thumb that I like to use for these plants is to allow the surface of the soil to dry out, and then water again. Maybe the top inch or so smaller pots. If you have a huge pot, maybe allow the top 2 inches to dry out.
Direct sun burns the leaves of most houseplants and causes their vibrant colors to fade. Water: The leaves of Calathea plants are easily damaged by the quality of the water you use. Hard water or soft water, water with a high chemical content (fluoride, chlorine, or salt), or water of poor quality causes leaf burn.
Calatheas thrive with a perfect balance of moisture and light, and browning edges is not uncommon and usually caused by one of two things: A lack of humidity, either in the environment or in its soil, which can also be expressed by the leaves curling. Overwatering, which leads to a build up of moisture around the roots …
Brown edges on leaves are common with calathea and may result from either fertilizing when the soil is dry or uneven watering. … Trim away brown leaf edges with scissors by following the natural curve of the leaf. It is not necessary to remove the entire leaf, as it will continue to grow even after trimming.
Simply cut the leaf with a sharp knife or a pair of scissors near the steam and discard the damaged leaf. Then your plant should turn its efforts to promoting growth in new leaves instead of trying to save dying leaves.
The most important thing is to keep it away from direct sunlight! Calathea leaves are very thin and sensible, they will easily burn if you expose them to direct sunlight. I often switch my plants from place to place, to give all of them as much light as they can get.
Calathea leaves can droop or die for a few reasons, such as either underwatering or overwatering. Dry air and cool air can also cause problems for Calathea leaves. So make sure to keep the plant in a warm area with some humidity, and water it regularly.
Repotting – It is a good idea to repot your calathea once every year or every other year to give it fresh soil and nutrients.
Start with watering when the top half inch or so of soil is dry, and give it little sips of water. You don’t need to drench the soil so much that there’s a lot of water draining through the bottom of the pot. Make sure your calathea is in a container with holes as well, as it absolutely can’t stand to sit in water.
As time passes, Calathea plants will also need repotting. This should be done in the spring about every two years. These plants do not like to be pot bound. If there are several rosettes at the base of the plant, now is the time to divide.
Water heavily, drench them, right after you repot. The water on the surface will evaporate relatively quickly, but moisture will still be trapped in the deeper soil… so that’s where the roots will do. You’ll be encouraging deep, healthy roots that anchor the plant AND provide it more access to water and nutrients.
Calathea prefer soil that is consistently evenly moist at all times but not soggy. If the top 2” of the soil become dry then your plant is ready to be watered. If you let the soil dry out too much, you may see browning, yellowing, or curling leaves, but don’t fear.
Whether grown as houseplants or in outdoor containers, potted plants require periodic repotting or they outgrow their pot. … Removing most of the old soil and repotting the plant can also help minimize disease and pest buildup in the soil that could affect the health of the plant.
Breaking up the root ball with hands or a knife prior to setting the plant into the hole helps to encourage root growth into the surrounding soil. Failure to do so usually causes the plant to continue to be root-bound (most plants are to some degree when they are purchased in containers).
Often, simply re-potting a plant after washing the roots will improve the health and vitality of houseplants and give them renewed vigor. … Place the houseplant onto the newspaper and use your fingers to gently remove as much soil as possible from the nooks and crannies of the roots.
Plants soak up everything that’s in their potting soil, including any chemicals or pesticides. Therefore, experts recommend washing the chemicals from the soil, also known as leaching, and replacing it every year before planting something new. “Potting soil often contains fungus spores or pests that have taken root.

Repotting doesn’t necessarily mean changing a plant’s pot: It can mean changing its soil or potting mix. … The size is important here: Typically when you move your plants to a larger pot, you‘re inclined to water more. Small plant + oversized planter + lots of soil + overwatering = killing with kindness.
When planting: Water plants as soon as you get them in the ground. Allow the water to soak in, then water again until the soil is thoroughly moistened. Week one: Water plants daily or every other day. Recently planted roots will absorb moisture from a small area until they begin to grow.
Prolonged root rot may lead to death of the plant. In extreme cases, plants affected by root rot may die within 10 days. Root rot is usually lethal although it is treatable. An affected plant will not normally survive, but may potentially be propagated.
