Taking care of Jar Calathea

We just can’t get enough of the beautifully patterned Calathea. That’s why we decided to use three different Calathea species in our Jars!

The Calathea plant

All three species of Calathea have a distinctive and striking look. Though their appearances differ, their growth habits and resilience are similar. An equal combination of beauty and toughness.


Condensation is part of the natural water cycle inside of the Jar and is a great indicator of how suitable the position of your Jar is. Ideally, one side of the Jar will be fogged up during the day. The plant will need about a week to acclimatise to a new spot.

If the Jar is completely foggy after 2 weeks, it is probably because the temperature in that spot changes often. Try moving the Jar somewhere with a more stable temperature.

If this does not do the trick, leave the Jar slightly open for a day or two to balance the humidity. Or open and lift off the top to wipe away the moisture with some clean paper towels.

Yellow or brown leaves

It is normal to see yellow or brown leaf tips. Should the discolouration spread throughout the leaf, this can mean that the leaf is ill. This does not necessarily mean that the illness will spread, but feel free to open the Jar and remove the discoloured leaf if it bothers you.

Wet stains on leaves

Large dark, wet stains on the leaves are a sign of an infection in that part of the plant. These stains can grow over time and eventually the leaf might fall off. If a leaf has a stain like this, get in there and remove the leaf!

Fungus on a leaf

Sick leaves are prone to attract fungus. If you see a carpet of fungus forming on a sick leaf, open the Jar and wash away any fungus you see with water.


Small insects can sometimes emerge from the soil. Little flies or spiders usually do not cause any harm. You can open the Jar and let them out if you want. 

Caterpillars, however, have a huge appetite and will damage the leaves. If you spot half-eaten leaves there, you should keep an eye on your Jar. Find and remove the caterpillar, and remove any damaged leaves to prevent disease.

Spilled soil on the glass

We do our best to prepare your Jar for the dangers transport poses to a fragile product. However, if your Jar has been jostled or shaken too much, soil can spill onto the glass. It would be a shame to let that spoil your view! This can easily be resolved by opening up the Jar and wiping the inside with some clean paper towels.
