House Plants: Calathea Roseopicta Care Guide

The Calathea Roseopicta is part of the prayer plant family and it’s one of the most stunningly beautiful plants in the world.

Its leaves look like they were painted by Mother Nature herself, with deep green tones brushed onto the leaves.

However, even though this is one of the most beautiful houseplants you can find, it’s also one of the most difficult to care for.

Benefits of Owning the Calathea Roseopicta

Houseplants have been proven to improve our quality of life by various studies. Living with nature is a natural stress reliever and plants improve the quality of air. Of course, all plants can achieve those two goals but the Calathea Roseopicta takes it a step further by exhibiting certain chemical traits.

With that said, let’s focus on air quality since that’s where the most beneficial traits come from.

Their large leaves are carbon dioxide eating machines! They are equipped with tiny pores that fill out their large surface area, consuming carbon dioxide and replacing it with oxygen at an astonishingly high rate.

Those same large leaves also serve as dust filters. Debris floating in the air is trapped on those leaves, making them natural air filters.

The Calathea Roseopicta also adds humidity to the air, improving the quality of air in your home.

Calathea Roseopicta Watering Guide

The Calathea Roseopicta loves for its soil to be damp all of the time, but oversaturation is still possible.

This is one of the factors that makes this plant high maintenance. Most people get this wrong, so here is a guide to ensure that you don’t make the same mistakes.

For starters, always wait until the top layer of soil is dry before watering. If you catch it just when the top layer is dry, then the underneath layers will still be moist. That’s when you should water it.

Remove the plant from the collector and add water until you see it seeping from the drainage holes. Do not replace the plant until you are sure the water has stopped seeping.

Also, water needs to be at room temperature or higher for best results. So either collected rainwater or tap water that has been left out overnight are the best choices. Colder water might stunt its growth.

Potting Guide for the Calathea Roseopicta

As mentioned in the previous section, this plant absolutely loathes soggy soil. It will develop root rot and its leaves will turn all shades of colors except the one they are supposed to be. So follow all watering guidelines to the letter.

Soil that contains at least one-third perlite will drain perfectly, making it less likely that you mess up its watering schedule.

Peat soils are usually recommended, but I’ve found that coco coir works better with this specific plant.

As far as the pot goes, just make sure that it contains drainage holes and you’ll be good. Plastic pots tend to work best because they keep the lower layers moist while allowing the top to dry out. Aesthetics don’t matter since the pot will be placed into a ceramic decorative pot.

Lighting Tips for the Calathea Roseopicta

Due to its natural habitat, the Calathea Roseopicta cannot handle direct sunlight so you will need to place it away from any windows where sunlight comes indirectly.

It needs to receive bright light, but not direct light. Don’t fall prey to all of the fancy marketing either.

While it can survive dark environments, it’s not going to thrive in them. Its leaves will become discolored and its health will suffer in dark locations.

Place the Calathea Roseopicta near a window with plenty of sunlight but to the side so that the sun’s rays are not directly hitting it.

It also makes an amazing bathroom or kitchen plant since it thrives with humidity.


Proper Fertilization Tips of Calathea Roseopicta

Under the best conditions, the Calathea Roseopicta can reach two feet tall and will grow fast!

The optimal seasons for feeding the Calathea Roseopicta are during the spring and summer.

You can use standard indoor plant fertilizer once per month to satisfy this plant. If you notice discoloration or any negative effects, then increase it to two feedings per month. Never go over that.

Calathea Roseopicta Propagation Facts

With the Calathea Roseopicta, it’s best to propagate by dividing the plant. Let me explain in an easy-to-follow, step-by-step method:

1. Remove the plant from the soil and divide the roots. Then carefully untangle the two sections and replant them in separate pots.

2. Make sure you replace the soil as well. Then water accordingly. You want the soil to be moist so just follow standard watering practices.

It can take up to a month for your new plant to recover and start growing so be patient.

Proper Air Growth Tips

Calathea Roseopicta is used to living in rainforests, so they love humidity and warm air. If your home is dry, then you’ll need to replicate rainforest conditions.

Do this by lightly misting the plant with water. Not only does this help the plant thrive, but it also empowers its natural filtration ability. Just be sure not to overdo it. Mist the plant no more than once every three days.

When you mist this plant, do it in the morning so that the natural sunlight evaporates the water. That way the leaves are not soggy.

Remember that the Calathea Roseopicta is a rainforest plant, so cold temperatures will damage it. Room temperature is okay but anything lower than that will hinder its growth.

Make sure to keep it away from air conditioning vents! I also recommend that you keep it away from heaters too since the air from those systems is usually too dry.

Pruning the Calathea Roseopicta

This plant doesn’t require a lot of pruning but you will need to occasionally remove dead and/or discolored leaves. Use scissors that are sterile.

Then cut away dead or damaged leaves at the base where they connect to the stalk. You can also trim individual leaves if they are only mildly discolored.


Pests and Diseases

Root rot is the number one problem that the Calathea Roseopicta will suffer from but that’s easily avoided by following the watering section of this guide.

Certain pests can also cause problems with spider mites and aphids being at the top of the list. Avoid these by removing dust from the plant’s leaves twice a week.

Also if you notice a pest problem, immediately separate it from other plants and take care of the problem. If a leaf is infested, cut it away.

There are also over-the-counter pest treatments that you can use if the infestation is severe.


The Calathea Roseopicta is one of the best indoor plants on the market. It comes with a lot of benefits with the only downside being that it requires extensive care.

As long as you follow the tips outlined in this guide, then it will thrive and your home will reap in the rewards!
