Challenges of Growing in Newfoundland and Labrador

1. Extreme and unpredictable weather

Newfoundland and Labrador regularly experience extreme weather conditions ranging from flooding to blizzards. Unfortunately, these weather events tend to be unpredictable, leaving gardeners with very little time to prepare and protect their crops. Therefore, greenhouse growing is recommended to avoid unexpected damage from the temperamental weather in this region.

2. Cool climate

The relatively cool climate presents another set of challenges for gardeners hoping to experiment with a wider variety of vegetables. Generally, heat-loving crops such as tomatoes and bell peppers won’t be able to grow solely outdoors in this province. Indoor growing or greenhouse growing is necessary to create the ideal environment for more warm-season crops.

3. Short growing season

​​Gardeners in this area face a variety of challenges due to the limited planting season. Without some type of indoor cultivation, many plants will likely struggle to mature in time, forcing gardeners to opt for more cool-hardy crops in an effort to avoid damage from early or late frosts.

The Benefits of Using a Greenhouse in Newfoundland and Labrador

A greenhouse is an effective tool to lengthen your growing season in Newfoundland and Labrador. Additionally, it will help protect your garden from severe weather and allow you to maintain the ideal climate for your crops. Gardeners will also be able to experiment with a wide range of vegetables, flowers, and more, that typically struggle to grow outdoors in this region.
