Tips for Winter Gardening in Your Garage

Gardeners in colder climates often despair when the gardening season ends and the long winter moves in. If you have a garage, with the right equipment and knowledge, you can extend your gardening season through the winter. Here are some tips to help you out from Hibiscus and More.

Weatherproofing Your Garage to Regulate Temperatures

Garage doors and windows are not made to be weatherproof, and let in too much cold air for successful winter gardening. If you have a single garage, covering the door with heavy plastic sheeting is effective at keeping out cold air. If windows are in good shape, they can also be covered with plastic sheeting, but this is a good time to assess the need for window repair or replacement. Garage windows are usually smaller, so repair and replacement costs average around $300 per window. Costs vary based on your locality and whether you need simple window repair or a total window replacement. Generally, the cost is offset by grocery savings on fresh, organic food.

Assessing Growing Space

Most homeowners already have numerous things stored in the garage, so creating space for growing plants involves some organization. First, determine how much you want to grow and how you are going to grow it. With inexpensive shop light fixtures and utility shelving, you can grow micro- and mini-greens efficiently and quickly, harvesting a few crops over the winter. For larger plants, such as tomatoes, five-gallon buckets are sufficient and can be placed under an array of lights or single spotlight grow-lights. Spacing suggestions are found on the back of seed packages or online.

Choosing Lighting for Best Growth

Proper lighting is essential for healthy plants. There are several lighting options to choose from, but these two are the most commonly used and more suitable than more powerful solutions for small-space growing.

•             CFL bulbs. The cheapest and often most sensible solution is regular fluorescent bulbs in an inexpensive shop-light fixture. Because they don't produce much heat, they can be used on each shelf of a shelving unit without burning the plants. They are the best choice for growing seedlings and small plants such as micro- and mini-greens.

•             LED lights. LEDs are more expensive initially than CFLs but use less energy. Less expensive LED grow lights often do not produce good results. They are more effective and powerful than CFLs but may not produce the full spectrum of light for some plants.

Controlling Heat, Humidity, and Air Circulation

In colder climates, an uninsulated garage needs supplemental heat, despite putting ample plastic sheeting on the walls. Your heating system must maintain a temperature of 65-70 degrees Fahrenheit for optimal growth. Using a propane or natural gas heater requires ventilation and the use of a carbon monoxide alarm system to prevent the gas from leaking into your home. Electric heat costs more but is ultimately safer. The best way to control humidity is with proper air circulation, which requires fans pointed in at least two directions to keep the air moving at all times.

Upgrades to Consider

There are several upgrades to consider that can not only make this space more functional for your green endeavors but also potentially add value to your home. First, consider installing proper insulation to maintain a consistent temperature, crucial for plant growth. Ventilation is another key aspect; installing an exhaust fan can help regulate humidity and air circulation. For watering convenience, you might also think about setting up a small sink or water source. Remember to document your work meticulously, as these enhancements can be appealing to future buyers who might appreciate a versatile, well-equipped garage space. Not only will these upgrades support your winter gardening, but they could also increase the overall appeal and value of your property.
