Do n't leave houseplants on windowsills behind the curtains on frosty nights, especially if your windows are not double glazed.
The best place to start if you're new to keeping plants is buying a few houseplants.
Before you go shopping for houseplants, consider where you would like to have plants in your house.
Light requirements vary from plant to plant, though most houseplants will do better in high light than in low light.
When choosing houseplants, pick plants that look healthy and are not incredibly root bound (where the roots have grown in circles around the pot).
