Quick Answer
COLD WEATHER GARDENING CAN BE ACHIEVED WITH PROPER PLANNING AND EQUIPMENT. USING GREENHOUSES OR COLD FRAMES CAN EXTEND THE GROWING SEASON BY 2-4 MONTHS, WHILE CONTAINERS CAN BE MOVED TO PROTECTED AREAS. PREPARING THE SOIL WITH COMPOST AND MANURE CAN ALSO IMPROVE FROST TOLERANCE.
Choosing the Right Crops
For cold weather gardening, choose varieties that are bred for cold tolerance, such as broccoli, kale, and spinach. These plants can thrive in temperatures as low as 25°F (-4°C). When selecting varieties, look for “cold hardy” or “frost tolerant” labels. Plant crops that mature quickly (40-60 days) to maximize the growing season.
Using Greenhouses and Cold Frames
A 4x8 foot cold frame can cost between $200-$500 and can extend the growing season by 2-4 months. Greenhouses can be more expensive (starting at $1,000 for a 4x8 foot model) but offer better insulation and temperature control. Consider using a hoop house or a poly tunnel for a more affordable option. These structures can be built in as little as a weekend and can provide a significant yield increase.
Soil Preparation and Mulching
To improve frost tolerance in your soil, add a 2-inch layer of compost and manure before the first frost. This will help retain moisture and provide nutrients for your crops. Mulching with straw or wood chips can help retain heat in the soil and protect roots from extreme temperatures. Apply a 2-3 inch layer of mulch in the fall to prepare for the cold weather.
