Summer in Chiclana de la Frontera calls for cooling the house down, and the air conditioning becomes our best ally against the heat. However, that fresh atmosphere has a less friendly side for indoor plants: it dries out the air and can leave their leaves with brown, crispy tips. At Losteflor we explain how to live with air conditioning without your plants suffering for it.
Why air conditioning dries out your plants
Air conditioning cools the room by drawing the moisture out of the air. That dry air feels comfortable for people, but the tropical plants we usually keep at home —such as pothos, peace lilies or ferns— come from humid environments and quickly feel the lack of ambient humidity. The first sign is usually unmistakable: the tips of the leaves turn brown, dry and brittle, and the green colour loses its shine. It is the same effect we notice on our skin or lips after spending many hours in an air-conditioned room. The good news is that you do not have to give up comfort in summer: with a few small changes of location and routine it is easily solved, and your plants will look lush again within a few days.
1. Move your plants away from the direct air conditioning flow
It seems obvious, but a cold, constant draught is lethal for a plant. The direct jet from the unit dries out the leaves within days and stops them recovering any moisture. Move them to a spot where the air does not hit them head-on: sometimes it is enough to shift the pot a couple of metres or turn it towards a more sheltered corner of the living room. Spaces near a window, but out of the line of the split unit, tend to be a good refuge.
2. Group your plants together to create a microclimate
When you place several plants together, they hold the ambient humidity better between their leaves and protect one another. This way you create a small humid «microclimate» that cushions the drying effect of the air. It is a trick that is as simple as it is decorative: grouping specimens of different sizes in the same corner of the living room improves how they look and, at the same time, their wellbeing. The denser the arrangement, the more humidity they share.
3. Place a tray with pebbles under the pot
Put a saucer or a tray with stones and a little water underneath the pot, making sure the base does not touch the water. As it evaporates little by little, that film creates a bubble of humidity around the plant that offsets the dryness of the air conditioning. Remember to top up the water every few days, especially when the unit runs for many hours at a stretch. It is a discreet and very useful solution for the most sensitive species.
Calatheas and ferns: the plants that warn you first
If you have calatheas or ferns, pay attention to their leaves: they are the first to warn you when the environment is too dry. Their thin leaves curl up or turn brown before those of hardier plants, so they work like a natural humidity thermometer at home. When you see them looking dull, it is time to review your routine and protect the rest of your plants from the effect of the air conditioning.

Frequently asked questions about plants and air conditioning
Does air conditioning kill plants?
It does not kill them outright, but a cold, constant jet dehydrates them little by little until the leaves dry out. By keeping them away from the direct flow and adding ambient humidity, they live perfectly well alongside the cooling system.
How do I know if my plants are suffering from the dry air?
The clearest clue is brown, crispy leaf tips, along with dull or curled foliage. Calatheas and ferns are the first to sound the alarm.
Can I keep indoor plants with the air conditioning on all day?
Yes. You just need to keep them out of the direct flow, group them together and give them an extra bit of humidity with a pebble tray. With those simple gestures, your plants will look healthy all summer long.
