Challenges of Growing in Alberta
1. Short growing season
Albertans are subjected to limited growing seasons with a brief peak period for gardening between the months of June and September. It’s important to monitor the weather and utilize a combination of indoor and outdoor gardening to extend this growing period.
2. High Altitude
The high-altitude mountainous regions of Alberta may experience a range of challenging growing conditions such as drastic temperature changes, low humidity, poor soil characteristics and more.
The Benefits of Using a Greenhouse in Alberta
Although the frost-free timeframe may be relatively short, a greenhouse will help extend the growing season in this region by several months. Alberta’s sunny climate pairs perfectly with a greenhouse by trapping the warmth and regulating the temperature inside throughout the colder seasons. Not only is this a wonderful way to maximize your growing time, but it also allows you to grow a variety of other plants that may struggle in an outdoor setting.
1. Extend your Growing Season
Without a Greenhouse:
Alberta’s planting season tends to last around 3-4 months each year. This short timeframe means many vegetables will be unable to reach maturity before the first frost without some indoor growing assistance.
With a Greenhouse:
Enjoy fresh vegetables well beyond the typical growing season by utilizing a greenhouse. Your planting season can extend to around 7-9 months annually, with the potential for even longer with Alberta’s sunny weather.
