Container gardens can be a great indoor addition when the seasons change and it starts getting cold. Careful consideration has to be given to indoor plants, as this unique growing environment will pose its own set of challenges.
Plants may deal with fluctuating temperatures, dryer air, shorter days, and a lack of sunlight. For these reasons, there are changes to what a plant needs to ensure they stay in optimal health through the cold season, and growers should be aware of what they can do to support their indoor grow and keep their plants in good condition.
Here are the top 5 ways to keep your indoor plants healthy this winter:
Plants grow slower in the winter, so less water is needed to keep them hydrated. Be careful not to water as much as during the warmer months, as this can lead to root rot.
Regulate the Temperature
Indoor plants survive best in much the same temperatures humans are comfortable in: between 65 and 75 degrees Fahrenheit in the day, and above 50 degrees or so at night. To make sure your plants don’t experience extreme fluctuations in temperature throughout the day, make sure they’re not located near areas where this can happen, such as poorly sealed doors or windows, or near radiators or ovens.
Humidity drops to 10 – 20 percent in houses that are heated during the colder months, while plants are most comfortable with a humidity level closer to 50 percent. It can be a good idea to place a humidifier near your plants to keep them comfortable.
There is generally less direct sunlight indoors. Check where the sun is in relation to your plants and try to relocate them to where they’ll receive the most exposure throughout the day. Since plants grow towards the sun, you may want to rotate the pots when they’re being watered so they can receive sun on all sides.
Since the plants have slowed down their growing cycle, they don’t need any fertilizer. In fact, this will only mess with their natural growth cycle. Cut back on fertilizer until early spring to give them a boost after the long winter!
An indoor environment is drastically different from the outdoors, which means you'll want to take steps to recreate the conditions that are ideal for your plants to grow and thrive. We hope you find these tips helpful when supporting your own indoor plants.
