How to Keep Your Houseplants Alive in Fall and Winter.<br />Many people struggle to maintain <br />their houseplants during fall and winter.<br />Here's how to make sure your <br />oxygen-giving friends stay alive.<br />1. Keep them warm, but not too warm, 65-75 degrees Fahrenheit during the day and above <br />50 degrees Fahrenheit at night are ideal.<br />Seal windows and doors, move to warmer rooms and keep away from heat sources such as fireplaces, radiators and heating vents.<br />2. Reduce watering, Most houseplants go dormant in fall and winter.<br />Only water if the soil is dry about <br />an inch or two below the surface.<br />3. Increase humidity in your home, Plants like humidity levels of about 50%.<br />If you don't have a humidifier, keep your plants together in the most humid rooms of your house, such as bathrooms or kitchens.<br />4. Clean them, Every couple of weeks, spray your <br />plants and wipe off their leaves.<br />By keeping your plants clean and dust-free, they're more able to soak in what little light winter offers.<br />5. Provide plenty of light, Plants need light more than <br />anything else in colder months.<br />Rotate your plants as needed or <br />shine a full-spectrum light bulb <br />on them for at least 12-14 hours a day
