Houseplants are natives of different climates and regions and this origin of the houseplants becomes extremely important while caring for them in different weather conditions. Several houseplants are natives of the warm tropics; some are desert dwellers, and some are native to cold climate.

Most foliage houseplants prefer temperatures between 65 and 70 degrees, so repeated cold waves and blasts of freezing air from an open door could be threatening for such houseplants.

Windowsills also provide a challenge. A temperature of 40 degrees can cause damage to tropical houseplants, and temperatures near windows, even double paned windows, can dip near that number.

You need to minimize the possible damage due to cold weather. Just make sure plants that sit on windowsills don’t have leaves touching the glass. At night, a heavy curtain drawn between the plants and the glass will provide extra protection.

Furnaces although keep homes warm, but they also lower down the humidity for the houseplants .Watch for brown tips on the leaves, one of the first signs that your houseplant is suffering from low humidity or that it is in a draft from the furnace register.

It is always better to water plants more to compensate for all this dry air. However, plants aren’t growing as actively in the winter because of shortened day length and cooler temperatures and don’t absorb as much water from the roots. That makes it easy to over water houseplants in the winter.

Plants that require watering once a week in the summer might only need water every 10 to 14 days in the winter. Make sure the top couple of inches of soil are dry before watering. Yellowing leaves or leaf drop is a sign of too much water.

You may create a microclimate by grouping several plants together and increase humidity. Set plants on trays or oversized saucers with a layer of gravel and water in the bottom. As the water evaporates from the tray, it humidifies the plants. This provides continuous humidity as opposed to an occasional spritz from a mister.
