Tips for Maintaining Your Greenhouse During the Winter

Keeping a greenhouse running during the winter months can be a challenging task, especially when dealing with cold temperatures and shorter daylight hours. But with some careful planning, you can ensure your plants stay healthy and thriving even in the harshest weather conditions!

The Importance of Winter Greenhouse Maintenance

During the winter, greenhouses can provide a vital lifeline for your plants, protecting them from the harsh elements outside. However, the colder months bring about their own set of challenges. Lack of light and cold temperatures can negatively impact your plants, causing them to wilt or even die. 

Moreover, maintaining a warm and well-lit environment in your greenhouse can become an expensive endeavor, with heating and lighting costs quickly adding up. Hence, it's crucial to find effective ways to maintain your greenhouse that won't break the bank.

Keeping Plants Healthy During Winter

1. Insulate Your Greenhouse

Insulation is key to reducing heat loss. Bubble wrap is a cost-effective and efficient insulator, and covering your greenhouse with it can significantly help retain heat

2. Install a Greenhouse Heater

To ensure your greenhouse stays warm enough during the coldest months, consider installing a heater. At Heartland, our premier greenhouse heating system is the RSI Greenhouse Heating System.

3. Use a Light System

With fewer daylight hours in winter, your plants may not get all the light they need for photosynthesis. Supplemental light systems can help combat this issue.

Winter Watering Requirements

During winter, plants' water requirements decrease due to slower growth rates and lower evaporation levels. Overwatering can lead to root rot and other diseases, so it's important to be mindful of your watering schedule.

Generally, you should water your greenhouse plants early in the day to give them enough time to absorb the water before the colder night temperatures set in. Always check the soil moisture level before watering; it should be dry to the touch at about an inch below the surface. 


In conclusion, maintaining a greenhouse during the winter months requires some extra effort and planning. However, by following these tips, you can ensure your plants stay healthy and vibrant throughout the season, ready to burst into life come spring.
