4. Edible Pathways: Imagine pathways bordered by ‘Mojito’ or ‘Dasheen,’ offering visual appeal and the promise of a future harvest. This truly embodies edible landscaping.
5. Shade Gardens: Many
6. Seasonal Interest: Even in cooler climates where they are treated as annuals, taro provides stunning foliage from late spring through fall, offering significant seasonal impact.
Common Mistakes to Avoid
Underestimating Water Needs: Taro is a thirsty plant. Allowing the soil to dry out, especially during hot weather, will stunt growth, reduce foliage size, and negatively impact corm development.Planting in Dry, Exposed Locations: Most taro varieties prefer moist soil and some protection from harsh, drying winds. Planting them in full, baking sun without adequate moisture can lead to scorched leaves and poor performance.
Overcrowding: While they can be planted relatively close for a dense effect, overcrowding can reduce air circulation, making them susceptible to fungal diseases, and diminish the size of individual plants and their corms.
Harvesting Uncooked Corms: Crucially, all taro corms must be thoroughly cooked before consumption. Raw taro contains calcium oxalate crystals that can cause irritation to the mouth, throat, and digestive system. Proper cooking neutralizes these compounds.
Ignoring Cold Sensitivity: Taro is a tropical plant. In regions with frost, it will die back. Failing to protect the corms or harvest them before the first frost will result in lost crops.
Using Inorganic Mulch in Wet Areas: While mulch is beneficial, using inorganic mulches like gravel in very wet areas can impede drainage further, potentially leading to rot. Organic mulches are generally preferred.
Expert Tips or Pro Insights
Soil Preparation is Key: For optimal corm production, start with well-drained yet consistently moist soil enriched with plenty of organic matter. Incorporating compost or well-rotted manure before planting is highly recommended.Fertilize for Foliage and Food: Taro benefits from regular feeding, especially nitrogen-rich fertilizers, to promote lush foliage. However, as the growing season progresses, switch to a fertilizer with a higher potassium content to encourage corm development.
The Importance of Consistent Moisture: Aim for consistently moist soil, but avoid stagnant waterlogged conditions for most varieties except those specifically adapted for bog environments. A layer of organic mulch helps retain moisture.
Harvesting for Flavor and Size: For the largest and sweetest corms, allow the plants to grow for at least 7-10 months. Harvest in the fall, before the first hard frost. You can also harvest smaller, younger corms throughout the season if desired, but they will be less substantial.
Overwintering in Cooler Climates: In USDA hardiness zones below 8, taro corms can be dug up after the foliage dies back and stored in a cool, dry, frost-free location (like a basement) over winter. Plant them again in spring after the danger of frost has passed. Alternatively, grow them as annuals.
Companion Planting: Consider companion planting taro with moisture-loving plants like hostas, ferns, or ornamental grasses for a cohesive tropical look.
Seasonal or Climate Considerations
Tropical and Subtropical Climates (USDA Zones 9-11): Taro can be grown as a perennial in these regions. Plant in early spring after the last frost. It will thrive throughout the warm season, producing multiple harvests of corms if managed well.Temperate Climates (USDA Zones 6-8): In these zones, taro is typically grown as an annual. Plant in late spring or early summer after all danger of frost has passed. The growing season is shorter, so select varieties known for faster maturity if possible. Harvest corms before the first frost.
Cooler Climates (USDA Zones 1-5): Taro is strictly an annual in these regions. Start corms indoors in pots a few weeks before the last frost to get a head start, or purchase established plants. Ensure they receive maximum warmth and sun throughout the short summer.
