The first step in winter greenhouse gardening is planning. As the rest of your garden is winding down, plant a few hardy or quick-maturing crops. Some cold-hardy cruciferous vegetables tend to do best when grown in cooler temperatures such as broccoli, cauliflower, cabbage, and kale. You can plant root vegetables like carrots, beets, and parsnips that also grow well under cold conditions. Quick-growing plants like lettuce and spinach are also great options because they mature so quickly and as for flowers and herbs, choose ones that tolerate the cold well such as snowdrops, camellia, witch hazel, chives, thyme, and parsley.
Before you make it a winter greenhouse, clean out any remaining organic material. Luckily, Palram – Canopia greenhouses are maintenance-free, but this is a good time to check on any equipment and make sure everything is working before the winter gardening months.
Control the Heat and Humidity with greenhouse heater
The colder it is outside, the more heat you need in your greenhouse. Because of this, you will want to set up a winter greenhouse kit to control the heat and humidity. If you have not yet, now would be a good time to invest in a greenhouse heater and hygrometer. The best option for winter gardening is fast, energy-efficient, and in addition to heating your plants, balances the humidity to prevent diseases.
An important thing to remember in winter gardening is that unlike spring or summer, winter harvests should be spread out to cover the entire season. Look at your schedule beforehand, harvest when necessary, and allow plants that can regrow to do so.
