While Minnesota’s climate is not ideal for taro cultivation due to cold winters and shorter growing seasons, you can create favorable conditions by using certain strategies outlined below.
Some taro varieties are better suited for cooler climates. When choosing seeds or corms for planting, look for cold-tolerant varieties such as:
These varieties may have a higher chance of success in Minnesota’s environment.
Select a sunny location in your garden where taro can receive at least six hours of sunlight daily. If your area lacks sufficient sunlight, consider using grow lights or planting near reflective surfaces that can enhance light exposure.

In Minnesota, due to the short growing season, it’s crucial to time your planting carefully. Start seeds indoors approximately 6–8 weeks before the last expected frost date (typically late April). Transplant them outdoors after all danger of frost has passed when soil temperatures are consistently above 60°F (15°C).
Maintain a temperature of around 70°F (21°C) using heat mats if necessary.
Transplanting Outdoors:
Taro requires consistent moisture; hence watering becomes crucial:
A balanced fertilizer high in potassium will support healthy growth:
While taro is relatively pest-resistant, it’s essential to monitor your plants for common pests such as aphids or spider mites:
To prevent diseases:
