Growing Taro Root: How to Plant, Care for, and Harvest Taro

Growing Taro Root
Growing taro root kicks off best in warm, damp conditions—plant the corms in rich, loamy soil and keep the ground consistently moist. Full or partial sunlight suits taro perfectly, and regular feeding with organic compost boosts growth. Be sure to plant taro roots 3 to 4 inches deep for healthy foliage and hearty tubers, then read on to master harvesting and enjoy your homegrown bounty.

Choosing Your Taro Variety and Preparing the Soil
Growing taro root brings me right back to a humid afternoon in Maui, hands deep in damp earth, marveling at the plant's broad, heart-shaped foliage.
To get started, first pick your variety—I prefer the hearty Colocasia esculenta, known for its impressive leaves and dependable root growth.
Once you've decided, select a spot in your garden with partial shade and rich, loose soil. This tropical plant thrives in warmth—ideally between 70-85°F (21-29°C)—and absolutely hates frost.
Taro Loves Moisture—But Don't Drown It!
If there's one thing I learned quickly, it's that taro adores moisture but despises stagnant water. It enjoys consistently wet feet, but standing water spells disaster.
To strike the perfect balance, add generous organic matter like compost or aged manure to your soil, which helps retain moisture while promoting excellent drainage.
"Good drainage isn't optional—it's mandatory. Taro growing in waterlogged conditions quickly develops root rot and fungal trouble."
Planting Your Taro Root
Once your garden bed is ready, here's how you plant your corms step-by-step:
- Select healthy, firm taro corms or tubers with visible buds.
- Dig holes about 6 inches (15 cm) deep, spaced 2 to 3 feet (60-90 cm) apart, allowing ample room for growth.
- Place corms with their budding tips pointing upward and gently backfill the soil.
- Water generously immediately after planting to settle the soil.
Ongoing Care and Feeding
While taro is fairly easygoing, it's voracious when it comes to nutrients. Feed your plants every six weeks with organic fertilizers rich in nitrogen and potassium to encourage healthy foliage and vigorous root growth.
When I first began growing taro, I underestimated its appetite—big mistake. Now I regularly mulch with compost or feed diluted fish emulsion, which keeps my plants flourishing.
Maintaining Ideal Moisture Levels
Taro relishes humidity and moisture. Keep the soil consistently damp but never soggy.
On particularly hot summer days, misting the leaves mimics its natural, humid habitat—your taro will thank you by growing lush and vibrant.
Protecting Your Plants from Pests and Diseases
While taro isn't notoriously pest-ridden, watch out for aphids and spider mites—they can't resist tender leaves. Spray plants gently with water to dislodge these critters, or use an organic neem oil solution if they persist.
The only serious problem I've encountered was fungal leaf spot during an exceptionally wet season. To combat it, I removed infected leaves promptly and ensured proper air circulation around plants.
Harvesting and Enjoying Your Taro Root
Patience pays off—taro takes 7-9 months to mature. You'll know it's ready when foliage begins to yellow and wilt.
Gently loosen the soil around the base of the plant and lift the root cluster carefully, shaking away the excess earth. Harvested taro roots can range anywhere from tennis ball to rugby ball-sized corms, depending on variety and growing conditions.
"Cook fresh taro thoroughly—never eat it raw—as it naturally contains calcium oxalate crystals that irritate the mouth and throat."
Roast your harvested taro root, mash it, fry it up into crispy chips, or try traditional Hawaiian poi. There's something uniquely satisfying about growing taro root at home and tasting your gardening success fresh from the earth.
Frequently Asked Questions About Growing Taro Root
What soil conditions best support taro plants?
Taro thrives in rich, loamy soils that stay consistently moist and drain well. Blend organic compost into the soil before planting to supply nutrients and maintain ideal moisture levels. Slightly acidic to neutral soil, with a pH range of 5.5 to 6.5, promotes healthy root growth.
How much sunlight do taro plants require?
Taro plants prefer partial shade to bright indirect sunlight. Direct sunlight during extremely hot afternoons may scorch their broad leaves. Providing dappled shade through trees or shading structures creates suitable growing conditions for vigorous foliage.
How frequently should you water taro?
Maintain consistent moisture by watering taro regularly, ideally keeping the soil slightly saturated but not standing underwater. Aim to water once or twice a week, providing enough moisture to permeate at least 12 inches (30 cm) deep, adjusting frequency according to rainfall and climate conditions.
What temperatures suit taro cultivation best?
Taro grows best in warm conditions, ideally between 70°F to 85°F (21°C to 29°C). Protect plants from temperatures below 50°F (10°C), as lower temperatures can slow growth and damage foliage. In cooler climates, consider planting taro in containers to move indoors during colder months.
How do you fertilize taro plants effectively?
Apply a balanced, slow-release fertilizer at planting time to promote steady nutrient availability. Supplement periodically with a nitrogen-rich organic liquid feed or compost tea every four to six weeks to encourage vigorous leaf and corm development.
What signs indicate taro roots are ready to harvest?
Harvest taro roots approximately 7 to 9 months after planting, when leaves begin to decline and turn yellow. Carefully remove the soil around the base to assess corm size—mature taro corms typically measure 4 to 8 inches (10 to 20 cm) in diameter and feel firm to the touch.
How can you safely handle and prepare harvested taro?
Raw taro contains calcium oxalate crystals, causing irritation if eaten raw or handled without protection. Wear gloves when harvesting and handling, and thoroughly cook taro by boiling or baking until tender to fully eliminate any irritants before consumption.
Growing taro root rewards patience and attention. Start with rich, moist soil, and keep those roots well-watered—taro won’t forgive a dry spell. Shade helps, but don’t skimp on sunlight. Watch for pests, and harvest only when those leaves yellow and corms feel firm beneath the soil. If you’re after unique flavors or want to try your hand with other intriguing edibles, mashua or tiger nut might be your next plotmates. Mastering growing taro root brings a taste of the tropics straight to your backyard, and nothing beats pulling your own corms from the earth after months of care. Here, patience pays off—one harvest at a time.
