As with all Canadian provinces, it’s important to note that the growing zones in this country do not use the same method as the USDA. Canadian zones consider climatic variables such as frost-free days, rainfall, and minimum temperatures and should not be used interchangeably with planting zones in the USA.

Characteristics of Alberta Planting Region
Alberta has a predominantly continental climate and experiences more sunshine than any other province in Canada, averaging 312 sunny days annually. Across the region, winters are typically dry, cold, and sunny, while summers can be warm and wet, with long bright days.
The average elevation of this region is 975m above sea level, and the province is known to have the most comfortable weather year-round than any other area in Canada.
Although this may vary across the province, on average, the frost-free growing season will begin towards the end of May and finish around mid-September. However, it’s always best to check the exact dates for your location.
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.

- Outdoor gardeners are more limited in their options due to shorter growing timeframes. However, some vegetables that will grow comfortably in Alberta’s outdoors include:
- Swiss Chard
With a Greenhouse:
The short planting seasons in this region make Alberta a prime candidate for greenhouse growing. Additionally, the sunny climate will keep your greenhouse warm and allow your plants to flourish.
