Challenges of Growing in Oregon
1. Severe Weather
The extreme weather conditions across the region present a variety of difficulties for gardeners. Raised garden beds and protective coverings are recommended to keep your hard work safe from the floods and winter storms in the area.
2. Temperature Extremes
Despite the generally mild climate across the region, Oregon will experience extreme temperature fluctuations throughout the year. Severe heatwaves in the summer months are expected, so it’s suggested to utilize indoor and ventilated growing to keep your plants alive and well.

The Benefits of Using a Greenhouse in Oregon
A Planta greenhouse can offer Oregonians an extended growing season, protection from extreme weather and early frosts, and a cool, ventilated area for pants to thrive even during a heatwave. Additionally, gardeners will have the ability to grow a much wider variety of plants than traditional outdoor growers.
1. Extend your Growing Season
Without a Greenhouse:
The growing season varies dramatically across the region and can sit anywhere between 90 and 250 days, depending on where you’re located. However, it’s important to note that various difficult weather conditions may create a challenging environment for gardeners despite the extended planting season in some parts of the state.
With a Greenhouse:
A Planta Greenhouse will allow gardeners to double or triple their growing seasons in Oregon. In higher altitude areas, the planting season can easily be extended between 7-9 months, while those living on the coast and in the valleys can potentially grow all year round.
