How much light do Marantaceae need?

Marantaceae are often sold as suitable for semi-shaded and shaded locations.

But what does that really mean for the plants? And what is actually the ideal location?

What is the natural habitat of Marantaceae?

Marantaceae grow in the shady undergrowth of rainforests, i.e., densely vegetated and far below the giant trees, which can easily reach heights of around 50 meters.

But has anyone ever asked themselves how comparable the lighting conditions of natural space are to the dark corner in our home?

Let's briefly shed some light on the basics in order to answer this question.

What do plants need light for?

Plants, no matter which type, need light in order to perform photosynthesis. During photosynthesis, plants use light energy to convert water and carbon dioxide into glucose (sugar) and oxygen in the chloroplasts.

In this process, glucose serves as an energy source for the plant, whereas oxygen is produced as a 'waste product' of the entire process.

Photosynthesis thus forms the basis of life for all living beings.

What exactly does photosynthesis do in the plant?

If plants receive enough light, they can carry out photosynthesis actively.

Overall, this in turn strengthens the plant's health and thus also improves its defenses against pests.

Additionally, sufficient light promotes strong growth; the plants may grow faster, denser and develop larger leaves.

What is the ideal location for our Marantaceae?

Even though Marantaceae are sold as shade-tolerant, this should be questioned first. Because 'shade-tolerant' only means that they can accept this location. That they would also thrive happily there is another matter entirely.

So finally the answer: No, the light conditions in the undergrowth of rainforests are not comparable to our dark corners of rooms.

All plant shelves are equipped with additional lamps.

Marantaceae like light, and they also like a lot of light!

A good location, without the need to install additional grow lights, is by an east- or west-facing window, as the plants receive evenly distributed indirect light there.

Placing a Marantaceae at a south-facing window should be avoided if possible, as direct, intense sunlight, especially in summer, can potentially cause burns on the leaves.

It is generally recommended, however - especially during the dark season - to provide Marantaceae with additional grow lights.

A perfect location provides the Marantaceae, among other things, with a constant supply of plenty of light throughout the year, for example by installing a full-spectrum grow light.
