How to Grow and Care for Calathea Musaica

Calathea Musaica Care

While this calathea is known for being a little less of a diva than some species in the genus, it still isn’t an ideal beginner houseplant. Here are the main care requirements for growing a Calathea musaica:

• Place in bright, indirect light or filtered sunlight.
• Plant in moist but well-draining potting soil.
• Water the soil just before it dries out completely.
• Fertilize monthly during the growing season with a balanced liquid fertilizer.
• Provide a high-humidity, warm, and draft-free environment.

Light

Try mimicking the dappled light these plants get in their native tropical habitats on the rainforest floor with filtered light through a window. Or, keep your Calathea musaica in an area of bright, indirect light.

Too much intense, direct sunlight quickly results in brown spots and leaf scorch, and the striking patternation will fade. But, if you go too shady, the variegation can diminish and the foliage won’t flourish.

Soil

Calathea has delicate roots, so you want a loose, lightweight potting mix, but it also needs the right balance of moisture retention and drainage. These plants are thirsty, but root rot sets in quickly if they are waterlogged.

An African violet mix is a ready-to-go option, or you could make your own blend using equal parts peat moss (or sustainable coco coir), perlite, and vermiculite. Peat moss retains moisture, while perlite helps improve drainage.

Water

These plants like to be kept evenly moist but are sensitive to overwatering, and root rot is common in soggy soil. Wait for the top few inches of soil to dry out, but don’t leave it too long after that, and don’t rely on sight to assess dryness.

Pop a finger in, and if the soil feels damp and comes off on your finger, hold off for a couple more days before rechecking. The leaves of the plant also start drooping when it needs a drink. If you’re unsure, use a moisture meter.

Temperature and Humidity

These tropical beauties won’t thank you if you stick them in a chilly room or one that experiences temperature swings or drafts. Consistent warmth and high humidity is the key.

It’s no wonder plant enthusiasts often pop Calathea musaica in steamy bathrooms. You’ll want a spot where temperatures remain above 60 degrees for continual growth, with the sweet spot being around 65 to 80 degrees.

One advantage of this calathea species is that its thicker leaves are more tolerant of dry air than some others in the genus. However, it still appreciates humidity levels of around 60 percent to produce the most impressive foliage.

To increase the humidity levels, try grouping tropical species, pop your plant on a pebble-filled tray with water, or invest in a humidifier.

Fertilizer

Fertilizing in moderation during the spring and summer growing period is best for Calathea musaica. Feeding too often or too much can scorch the foliage, so stick with a weak dose of nitrogen-rich fertilizer around once a month.

Pruning

You won’t have to habitually hack your Calathea musaica with shears. These plants need little to no pruning. It’s just a case of removing dead or dying leaves at the base of their stems. This saves your plant from looking untidy and directs the energy to healthy growth.

Potting and Repotting Calathea Musaica

Calathea musaica aren’t fans of having their roots disturbed, so tread carefully when repotting this plant. Thankfully, they are relatively slow-growing, so you should only do this every two to three years.

Don’t try to get all the old soil off the root ball—loosen it gently, move the plant to a pot a couple of inches bigger, and then fill it with some new nutrient-rich, loose potting mix.

Common Pests

Because your Calathea musaica loves high humidity, they can sometimes be bothered by pests drawn to muggy conditions. Look out for fungus gnats and mealybugs, and if conditions are too dry for your plant, spider mites might settle on this species.

Thankfully, if you get in there quickly, you can get rid of pests like mealybugs before major infestation sets in. Clean each leaf with a damp cloth and then use neem oil or insecticidal soap to keep any bugs from making a comeback.

Common Problems with Calathea Musaica

While caring for a Calathea musaica can be tricky, thankfully, the plant offers some early warning signs that you need to adjust conditions before you kill it off. Watch out for the problems below.

Leaves Turning Brown

Browning leaf tips and edges usually indicate you need to increase humidity levels or cut back on watering. Brown spots can also develop if your Calathea musaica is sitting in a location where it’s subject to too much intense direct sun.

If it’s only older leaves that are browning on the tips, it might not be cause for panic. This happens naturally, no matter how diligent you are with the plant’s care.

Curling Leaves

Prayer plants like the Calathea musaica close their leaves at night before reopening them at dawn. However, if the lush, large leaves of your plant are staying curled up during the day, consider if you’re letting it get too dry.

Drooping Leaves

Occasional leaf drooping during the day is normal on even the healthiest Calathea musaica. As long as they perk up again at night, it isn’t something to worry about. When they stay droopy, it’s typically a sign your plant needs more water or higher humidity levels.

Leaves Turning Yellow

Yellowing leaves on your Calathea musaica usually mean you’re going overboard with water or that your plant is in a spot where it’s receiving too much direct sunlight. If you’ve ruled both things out and your plant’s leaves are still discoloring, you could have it sitting in a drafty or cold location.
