Jicama is a mild, crunchy root vegetable that’s easy to grow and great for snacking. Here's everything you need to know, to plant and grow jicama in your garden.

“Jica-what?!?” the kids shouted, when I got my first jicama seeds in the mail.

Jicama (pronounced hick-uh-mah) is a tasty root vegetable that’s easy to grow and great for snacking. It’s mild and crunchy, and tastes like a cross between an apple and a water chestnut.

We eat jicama raw, add it into green salads, and make Zesty Summertime Slaw. It's also popular as a snack with chile and lime.

It's been several years since that first batch of seeds arrived, and I've learned a lot about how to grow jicama since then.

It grows happily in the garden all summer long and doesn't need much attention. Then in the fall, you get to enjoy the fruits of your labor (roots of your labor?).

Growing Jicama: Varieties

Even though jicama looks like a potato, you can’t chop up a jicama root and plant it like a potato. It has to be grown from seed, and it’s an annual (you have to replant it every year).

Jicama is a specialty vegetable and you probably aren’t going to find it at your local big-box garden store. I usually order mine from Kitazawa Seed in Oakland, CA.

Jicama seeds are large and sort of square. You get about 25 seeds in a packet, which lasts me for a couple of years.

Sun, Water, Soil

Jicama needs lots of sun, because it’s a tropical plant. It has a loooooong growing season (150+ days), so choose a spot where the plants can grow, undisturbed, for the whole summer.

Jicama grows best in sandy loam soil with good drainage. Because my soil has lots of clay, I grow it in raised beds with plenty of homemade compost and worm castings.

They also like to have extra potassium in the soil. You can add high-potassium organic fertilizer, or--believe it or not--by burying a chunk of banana peel along with the seedling.

You can grow jicama in containers; a good rule of thumb is one plant per 7-gallon container. I like to grow jicama in Smart Pots because they're durable, made in USA, and won't overheat like plastic pots.

If you're growing in a pot or container, remember to water frequently so the soil doesn't dry out. Learn more about container gardening here.

Growing Jicama: Planting & Spacing

Jicama seeds can be tough to start. I like to start mine in a damp paper towel to ensure they are viable. After the seedlings have sprouted, I plant them outside. Because they have such a long growing season, I plant as soon as possible after our last frost date (usually in March).

Space seedlings 12 inches apart. The jicama is a root/tuber that grows underground and the plant makes a vigorous vine. You could train the vine to go up a trellis--I usually just leave it grow along the ground.

The vine and leaves are poisonous, so don’t eat them. You want all of the plant’s energy to go to the root, so don’t let it go to seed. Pinch off any flowers as you see them.

You’ll get one jicama tuber per plant (on rare occasions you might get two smaller ones).

Pests, Diseases, Companion Plants

Once your jicama plants are established, there isn’t much that will bother them. They aren’t bothered by aphids or other garden pests. This is because the leaves, stem and seeds contain the poison rotenone. Don’t let your garden helpers munch on this plant!

Companion plants are plants that help each other grow better. There's a great reference book about companion planting, called Carrots Love Tomatoes (a must-read for any vegetable gardener).

How to plant and grow jicama in your garden.

While there aren’t specific companion plants that help jicama grow, I usually plant them at the back of the garden bed because of the long vines they produce. They’ve shared a garden bed with my carrots and zucchini plants for the last couple of years, and everything has done well.

Harvesting & Eating

After about 150 days, the plant will start producing the root underground. The vine might die back at this point, and if it does that's a sure sign that it's time to harvest. Otherwise, about 6 months after you planted, it’s time to harvest your jicama.

Follow each vine back to the tuber in the soil. Using your hands or carefully using a shovel/fork, lift the jicama out and dust off the excess soil. Cut off the vine.

Depending on how well they grew, your jicama may be as small as an orange or almost as big as a football. Sometimes they can be woody if they get too big, so don’t be upset if they come out pretty small.

Do not store the jicama in the ground until ready to eat, as you would carrots. They will rot from the inside as soon as a bit of frost touches them (ask me how I know).

Congratulations! You’ve harvested your what? Wash off the outside and cut off the brown skin and fibrous coating underneath.

You can eat the jicama root raw in a salad, make Zesty Summertime Slaw, or add it to stir-fry. We enjoy it raw, cut into sticks and dipped in Caesar dressing. Yum!

    Hello! Thanks for all the info on Jicama.
    I do have a few questions regarding if it is the right time for me to start planting Jicama seeds in my garden. I live in Arizona and it is already approaching over 100 degrees daily these days in May, and it will only go up in the coming weeks. I now understand it needs a long growing season, so should I plant them now? Or is that too hot for them? My first frost date isn’t till early to mid December so I will have a long season. I can’t seem to find any specific details and tips elsewhere on the internet about growing jicama in Arizona, but I also know it grows well in Mexico, which has similar see if hoy summers. Please do let me know any advise and tips you may have regarding the same. I spent a hefty sum to get hold of 22 jicama seeds and I don’t want to waste them. Thank you in advance!

      Good question, Carol! I did some searching and it sounds like planting them now will be OK. If you notice the leaves starting to burn, make sure the plants are getting enough water and shade them during the hottest part of the day. I put a patio umbrella over my tender plants when it gets really hot here. 🙂 Happy growing!

      • Carol on May 15, 2021 at 2:53 pm

        Thank you so much. Most of the seeds havr sprouted and I am keeping them indoors rigjt now till they grow to a healthy level and then I will transplant to an area like you suggested. 🙂

          Awesome! Keep me posted!

    I grew jicama for the first time this year. Some of them were enormous while the rest were merely huge! The largest is a 7 pounder. Some of the jicama were strangely shaped, almost pumpkin shaped. Is there something I can do to insure they are globe shaped? I wondered if the soil might be a factor. I cannot find anything online and hope you can help.

    what’s the best way to store extra harvest as I find they spoil quickly when I buy jicama

    • Pam on April 30, 2019 at 6:08 pm

      Good question! I leave mine on the counter until I’m ready to use it. If the skin is intact, it can last for a few days.

  5. William on April 11, 2019 at 4:57 pm

    Well done, Pam! After checking at least a dozen sites, for some well written, comprehensive instructions, on how to grow Jicama. So far, yours are the best I have found! Many thanks, not only for the basic growing steps, but for personalizing them, with your own tips & experiences.

    • Pam on April 15, 2019 at 7:29 pm

      Excellent! Glad these tips are helpful to you. Happy gardening!

    About 6 years ago we got one in our bountiful basket and I really did not know what it was, so it sat on the counter for 2 months or so. It got pushed to the side and kinda forgotten. Well every few months I strip everything off the counter and do a deep clean, moved a big basket and it was behind it, growing from the tip! Just a little sprout. So I stuck it in a pot of soil next to our pellet stove (this was November I think) it got about 2 hours of sunlight a day and it GREW LIKE CRAZY!! The vine was probably 15 foot long. I ended up giving it to my Dad because we had a 9 month old and could keep him away from it. I don’t think it last long at his house because his wife has a black thumb lol. But it was a pretty cool experience.
