When To Plant Taro Root

The best time to plant taro root is in the late spring or early summer, once the soil has warmed up to at least 60°F (15°C) and all danger of frost has completely passed.
 
If you’ve been wondering when to plant taro root in your garden, this timing is your golden rule because taro is a tropical plant that thrives in warmth and absolutely hates cold weather.
 
Planting taro root too early, when the ground is still chilly, can cause the corms to rot or simply sit there without sprouting, which is a total waste of your effort.
 
On the flip side, planting taro root too late means you might run out of growing days before the cooler fall weather arrives, leaving you with small, underdeveloped corms.
 
In this post, we’ll take a close look at the best windows for planting taro root, how soil temperature and your local climate play a role, and some practical tips so you know exactly when to plant taro root in your own backyard.
 
Let’s dig into the details and get you set up for a thriving harvest of this starchy, delicious root.
 

When To Plant Taro Root: The Best Timing Explained

When to plant taro root really comes down to understanding that this plant is a warm-season crop that needs a long, hot growing season to mature properly.
 
Taro root, also known as colocasia esculenta, is native to Southeast Asia and has evolved to grow in marshy, tropical conditions where the air and soil stay warm for months on end.
 
So, when you’re deciding when to plant taro root, you need to think about replicating those warm, humid conditions as closely as you can in your specific growing zone.
 
Generally speaking, you should wait until nighttime temperatures are consistently above 50°F (10°C) and the soil temperature at planting depth has reached at least 60°F (15°C).
 
For most gardeners in temperate regions, this perfect window for planting taro root opens up about two to three weeks after your last expected frost date.
 
Let’s break down the key factors that influence this timing so you can pick the exact right moment for planting taro root in your garden.
 

1. Soil Temperature Is The Real Boss

The single most important thing to watch when trying to figure out when to plant taro root is the temperature of the soil itself, not just the air.
 
Taro corms will not even begin to wake up and sprout if the soil is anywhere near 50°F (10°C) because they essentially go into a state of dormancy in cold ground.
 
You want to use a soil thermometer and check the temperature at about 4 inches deep in the morning when the soil is at its coolest.
 
If that reading consistently shows 60°F (15°C) or higher for a week straight, then that’s your clear signal that the time to plant taro root has arrived.
 
Planting taro root in soil that’s too cold will not just delay sprouting; it will likely cause the corm to turn mushy and rot underground, and you’ll have no chance of seeing a plant emerge.
 

2. Your Last Frost Date Is A Crucial Marker

Since taro is so sensitive to cold, your last frost date is a major clue for determining when to plant taro root in the spring.
 
You should never plant taro root before your last frost date, as even a light frost can kill the tender new shoots if they happen to emerge early.
 
A safe rule of thumb is to wait at least two weeks after your last frost date, but really, a full month after is even better for ensuring the ground has had time to warm up.
 
Many seasoned growers will watch the local forecast and wait for a stretch of warm nights with lows above 55°F (13°C) before they commit to planting taro root.
 
You can also give your taro a head start by planting the corms in large pots indoors about 6-8 weeks before you plan to set them out, which helps you stretch the season in cooler climates.
 

3. Climate And Growing Zones Change The Calendar

Your specific location on the map plays a huge role in when to plant taro root because you could be gardening in Florida or in the northern US.
 
If you live in USDA hardiness zones 9 through 11, where winters are mild and frost is rare, you might have a much longer window for planting taro root.
 
In these warmer zones, you can often plant taro root as early as March or April, and sometimes even in late winter if the weather stays warm.
 
On the other hand, if you’re in zones 6 or lower, you’ll likely be looking at planting taro root in late May or even early June because the soil warms up much later in the year.
 
Gardeners in cool climates might also need to consider planting taro root in containers or raised beds where the soil heats up faster in the spring sunshine.
 

How To Prepare For Planting Taro Root At The Right Time

Once you’ve figured out when to plant taro root based on your climate, the next step is getting your garden bed ready so those corms take off running.
 
Taro loves moist, rich soil, so you’ll want to work in plenty of compost or well-rotted manure before you plant taro root.
 
This not only feeds the plant but also helps the soil hold onto moisture, which is critical because taro is quite thirsty and can’t stand drying out.
 
Also, think about planting taro root in a spot that gets full sun to partial shade, with at least 6 hours of direct sunlight each day for the best growth.
 
If you live in a hot desert area, a little afternoon shade can actually be a lifesaver for your taro plants during the hottest part of the summer.
 
And because taro naturally grows in wet, boggy conditions, you can even plant it along the edge of a pond or in a shallow trench that stays flooded.
 

1. Soaking And Pre-Sprouting Taro Corms

Before you plant taro root, it’s a smart idea to soak the corms in lukewarm water for about 24 hours to rehydrate them and kickstart growth.
 
You can also pre-sprout your taro by placing the corms in a warm, shaded spot with slightly moist soil for about two weeks before planting.
 
This gives the eyes of the taro a chance to swell and start pushing out little shoots, which shortens the time it takes to see growth above ground.
 
Pre-sprouting is especially helpful if you’re planting taro root later in the season and want to give it as much time as possible to mature.
 

2. Planting Depth And Spacing For Success

When you’re ready to plant taro root, dig a hole that’s about 3 to 4 inches deep, square, so the corm sits just below the soil surface.
 
Place the taro corm with the pointed top facing upwards and the flat bottom down, then cover it with soil and water it in well.
 
Space your taro plants about 3 feet apart in rows that are 3 to 4 feet apart, because each plant can get quite large and needs room to spread.
 
If you’re growing taro in containers, make sure each pot is at least at least 2 feet wide and deep, and you can plant one single corm per pot.
 

Tips For Extending The Taro Growing Season

Even if you’ve nailed down when to plant taro root, you might still face a short season, especially up north, and there are tricks to stretch it.
 
One popular method is to start your taro indoors as early as 6 to 8 weeks before your last frost, so you have big, established plants ready to go.
 
You can also use black plastic mulch on the soil surface before you plant taro root, as this warms the ground much faster in the spring.
 
As the fall approaches and nights start getting cool, covering your taro with a floating row cover or building a cold frame can add a few extra weeks of growth.
 
And if you’re worried about frost coming before your taro is fully mature, you can always dig up the corms early and let them finish curing in a warm, dry place.
 

1. Watering And Feeding Schedules

After you plant taro root, you’ll want to keep the soil consistently moist, but never soggy, since taro loves water but hates waterlogged roots.
 
A deep watering about two to three times a week is usually perfect, but you’ll need to increase that during hot, dry spells.
 
Feed your taro plants with a balanced fertilizer, like a 10-10-10 formula, about a month after planting and then again every six weeks.
 
Taro is a heavy feeder, so giving it regular nutrients ensures you get big, juicy corms when it’s time to harvest.
 

So, When To Plant Taro Root?

When to plant taro root is all about waiting for warm soil and stable, frost-free weather to give your plants the best start.
 
You’ll want to plant taro root in the late spring or early summer, aiming for soil temps of at least 60°F (15°C) and mild nights.
 
You can also plant taro root earlier in warm climates, but cool-climate gardeners must be patient and wait until late May or June.
 
So, when to plant taro root in your own garden is a matter of watching your local weather and soil conditions closely.
 
That perfect time to plant taro root will reward you with beautiful green leaves and a hearty harvest of earthy, delicious corms.
 
Get your timing right, and you’re well on your way to enjoying homegrown taro in soups, stews, and roasted dishes.
 
Happy planting, and may your taro patch be as lush as a tropical paradise.
