Origin
Calathea Roseopicta is native to Central America and thrives in tropical jungles. This plant belongs to the Calathea family and grows best in warm, humid conditions.
Light
Calathea Roseopicta is a tropical plant that requires bright light to thrive. It will do well in a south-facing window, but it will also do well under artificial lights. This species of Calathea does not tolerate low-light conditions for very long. It may also stop growing or lose its leaves if it receives enough light for too long.
Watering
Water your Calathea when the soil feels dry. Don’t let the plant sit in water, and avoid over-watering; if you do, it will rot and die.
Calathea plants are one of the few where you should under-water them. In general, this species can tolerate a bit of under-watering without consequences if Calathea doesn’t grow, water less often until its root system is established.
Humidity
If you have a humidifier, place it near your Calathea Roseopicta. It’ll increase your home’s humidity during winter. Misting the plant once or twice daily will help increase its humidity. Moving your Calathea Roseopicta to a drier location can decrease its humidity level. Levels should be kept in the range of 50-70%.
Soil
Calathea roseopicta is native to Brazil. Its ideal environment mimics its natural habitat. The plant likes soil that’s slightly acidic and well-draining. Its soil should have a pH between 5.5 and 7.0, or 6.5 to 7.5, if you use Miracle-Gro potting mix. Keep the soil moist without letting it dry out completely.
Temperature and Humidity
Calathea Roseopicta requires a temperature range of 60-80°F and humidity between 50-70%. These growing conditions are the same for Calathea Roseopicta as for most houseplants.
Pests and Diseases
Calathea Roseopicta is susceptible to various pests and diseases. Here are some common pests and diseases you may encounter in your Calathea:
- Spider mites
The webs can identify these tiny pests. They spin on the undersides of leaves, which will appear yellow or pale green. To treat spider mites, spray your plant with water from a spray bottle. If that doesn’t work, try an insecticidal soap or neem oil spray (available at most local nurseries).
- Mealybugs
Mealy bugs are white, cottony-looking insects. They feed on plant sap using piercing/sucking mouthparts. These mealy bugs can be difficult to spot as they blend well with a plant’s natural color scheme.
You can usually spot them by looking for shaped black spots. It’s where they congregate on leaves or stems. Remove damaged leaves and treat your houseplant with insecticidal soap to get rid of them. Also, spraying an alcohol solution onto infected areas. Alcohol will kill adult mealybugs once found!
- Aphids are small green insects with pear-shaped bodies. These insects have long antennae protruding from their heads. Their bites leave tiny bumps on Calathea Roseopicta leaves. These bites look like those caused by thrips infestations but don’t appear that red.
Soil
Calathea roseopicta is a low-light plant, and it’s best kept in dry soil. The tropical rainforest species need a slightly acidic soil with medium moisture. Use a cactus or potting mix to create the right conditions for your Calathea. Ensure that your mix has been amended with perlite or horticultural sand.
To improve drainage, add 1/4 cup of coarse sand to every gallon of soil (1/8″ to 3/4″). You can add extra perlite to improve drainage without losing the weight and texture of the potting mix.
Fertilizing
You should fertilize your plant every two weeks. To do this:
- Add fertilizer to the soil and not to the water. You can use a liquid fertilizer made for plants or a fish tank water conditioner.
- Add a couple of drops of fertilizer per gallon of water.
- Pour it into the potting soil around your Calathea Roseopicta.
The amount of fertilizer you use depends on how big your plant is. Start with one teaspoon and adjust as needed.
When should you fertilize?
It’s best to fertilize when your Calathea grows new leaves. It will help them grow large and healthy without getting weighed down by too much food! If some leaves are smaller than others, add more food during those times.
Repotting
If you want to keep your Calathea healthy and happy, it’s important to repot them regularly. It’s recommended that you repot every two to three years. The fertilizing frequency will depend on the soil conditions your plant is growing.
A good way to tell if your Calathea needs repotting is by looking at the roots. If there are yellow leaves or brown spots on the foliage, it needs more water or less fertilizer. If they’re getting very long and tangled, it may be time for some new soil!
Propagation
You can propagate your Calathea by taking cuttings.
- Take a cutting at least 6″ long in spring or summer, and cut it below the node on the stem.
- Dip both ends of your cutting in the rooting hormone.
- Wrap the cutting to keep it from drying out using plastic wrap. Next, place it in a warm (70-75 degrees), humid environment for about 10-14 days until new roots have appeared. (Only leave them for two weeks!)
- Plant your new plants in pots with good drainage holes. Don’t water them until they start growing again and you see white roots poking around their base. It could take several weeks!
