Plants near a radiator
Plants can stand in a room with a radiator or heater, but not on it or right up against it: the hot air rising off it dries their leaves and makes the soil dry out fast. The ones that cope best near the heat are plants that tolerate dry air, such as snake plant, ZZ plant, cast iron plant, and succulents like jade plant and aloe.

How to tell if the air is too dry for your plant
Look at the tips and edges of the leaves. If they turn brown and crisp, or leaves, buds and flowers drop early, feel the soil a few centimetres below the surface. If it’s still damp down there, the air is too dry. If it’s dry there too, the plant is more likely thirsty.

What a radiator changes for a plant
The soil dries sooner
With the heating on, the pot loses water faster than it would in a cool corner.
Feel the soil a few centimetres below the surface and water only if it’s dry down there.
Dry air
Central heating dries the air indoors, and tropical plants suffer for it.
A wide saucer of wet gravel, or a few plants grouped together, keeps the air around the leaves a little more humid.
Leaves against the radiator
A leaf that touches the radiator, or sits in the hot air rising off it, dries out and scorches.
Move the pot to one side or further away, until no leaf feels the heat.
Questions about plants near a radiator
How far from a radiator should a plant be?
Far enough that the leaves don’t feel the hot air. With the heating on, hold your hand where the leaves are: if you can feel the heat rising, move the plant.
Can a plant sit on the windowsill above a radiator?
A succulent can, as long as no leaf hangs over the radiator. A tropical plant such as a monstera or a fern will suffer from the dry air there. At night, don’t leave it shut between the curtain and the glass, where it gets cold.
Does misting the leaves help with dry air?
Not much: the water evaporates within minutes, and leaves that stay wet are more prone to leaf spots. A wide saucer of gravel and water does more, with the bottom of the pot sitting above the water.

When you switch the heating on, you note it on the plant, and it asks you to feel the soil, which now dries sooner.
