Growing a pomato plant lets you harvest both tomatoes and potatoes from a single plant, making it a fun and efficient gardening project. This grafted wonder combines two crops in one, perfect for small spaces or curious gardeners.
Have you ever wished you could grow two vegetables in the space of one? Meet the pomato plant—a clever, space-saving marvel that gives you both juicy tomatoes and hearty potatoes from a single stem. It sounds like something from a science fiction garden, but it’s 100% real and surprisingly easy to grow. Whether you’re a seasoned gardener or just starting out, the pomato plant offers double the harvest fun with half the effort.
The pomato isn’t a naturally occurring plant. Instead, it’s created through a process called grafting, where a tomato plant (the scion) is joined to a potato plant (the rootstock). This fusion allows the upper part to produce tomatoes while the roots develop potatoes underground. The result? One plant, two delicious crops. It’s a fantastic way to maximize your garden’s productivity, especially if you’re working with limited space like a balcony, patio, or small backyard.

What Exactly Is a Pomato Plant?
The pomato plant is a horticultural hybrid created by grafting a tomato shoot onto a potato root system. This technique has been used for decades in commercial and experimental gardening, but it’s now becoming popular among home gardeners looking for novelty and efficiency.
How Grafting Works
Grafting involves joining two different plants so they grow as one. In the case of the pomato, a healthy tomato plant is carefully attached to the stem of a potato plant. Over time, the tissues fuse, allowing nutrients and water to flow between both parts. The tomato grows upward, producing fruit, while the potato develops tubers beneath the soil.
Not GMO—Just Clever Gardening
Despite its futuristic look, the pomato is not genetically modified. No lab tweaking or DNA splicing is involved. It’s purely a manual grafting technique, much like what’s done with fruit trees. This makes it a safe, natural option for organic gardeners.
Why Grow a Pomato Plant?
There are plenty of reasons to try growing a pomato plant, especially if you love fresh produce and creative gardening.
Double the Harvest
Imagine picking sun-ripened tomatoes in July and then digging up fresh potatoes in October—all from the same plant. That’s the magic of the pomato. You get two crops without doubling your planting space or effort.
Perfect for Small Spaces
If you’re gardening on a balcony, rooftop, or in a tiny backyard, space is precious. The pomato plant thrives in containers, making it ideal for urban gardeners. A single large pot can support one pomato plant, giving you both tomatoes and potatoes without needing rows of garden beds.
Educational and Fun
Kids and adults alike are fascinated by the pomato. It’s a great way to teach children about plant biology, grafting, and where food comes from. Watching two different vegetables grow on one plant is like having a living science experiment in your yard.
How to Grow a Pomato Plant
Growing a pomato plant is similar to growing regular tomatoes and potatoes, but with a few special considerations. Here’s how to get started.
Choose the Right Variety
Not all tomato and potato varieties work well together. Look for pomato plants that are already grafted and sold as a unit—many garden centers and online nurseries offer them. Popular tomato varieties used include cherry or beefsteak types, while the potato rootstock is often a standard white or red variety.
Start with a Large Container
Because the pomato plant produces both above- and below-ground crops, it needs deep, spacious soil. Use a container that’s at least 18 inches deep and 12–14 inches wide. Make sure it has drainage holes to prevent waterlogging.
Use Quality Potting Mix
Fill your container with a rich, well-draining potting mix. Avoid garden soil, which can compact and hinder root growth. Mix in some compost or slow-release fertilizer like Osmocote Smart Release Plant Food to give your plant a nutrient boost throughout the season.
Plant in Full Sun
Pomato plants need at least 6–8 hours of direct sunlight daily. Place your container in a sunny spot—south-facing patios or balconies are ideal. Without enough light, the plant may produce fewer tomatoes and smaller potatoes.
Water Consistently
Keep the soil evenly moist but not soggy. Tomatoes hate dry soil, and potatoes don’t like wet feet. Water when the top inch of soil feels dry. In hot weather, you may need to water daily. A moisture meter can help you stay on track.
Support the Plant
As the tomato part grows, it will need support. Use a sturdy stake or tomato cage to keep the plant upright. This prevents branches from breaking under the weight of fruit and keeps the foliage off the ground, reducing disease risk.
Fertilize Regularly
Feed your pomato plant every 2–3 weeks with a balanced liquid fertilizer. Once tomatoes start forming, switch to a fertilizer higher in potassium to encourage fruit development. Avoid over-fertilizing, as this can lead to lush leaves but fewer fruits.
Caring for Your Pomato Plant
Like any plant, the pomato needs attention to thrive. Here are some care tips to keep it healthy and productive.
Watch for Pests and Diseases
Tomatoes and potatoes are both susceptible to pests like aphids, whiteflies, and potato beetles. Check your plant regularly and remove pests by hand or use insecticidal soap. Diseases like blight can affect both parts of the plant, so ensure good air circulation and avoid overhead watering.
Prune for Better Growth
Prune suckers (small shoots that grow between the main stem and branches) on the tomato part to encourage stronger growth and more fruit. Don’t prune the potato part—it needs all its leaves to feed the tubers below.
Mulch to Retain Moisture
Add a layer of mulch—like straw or shredded leaves—around the base of the plant. This helps retain moisture, regulate soil temperature, and suppress weeds.
When and How to Harvest
One of the best parts of growing a pomato plant is the dual harvest. Here’s how to know when it’s time to pick.
Harvesting Tomatoes
Tomatoes are ready when they’re fully colored and slightly soft to the touch. Pick them gently to avoid damaging the plant. Cherry tomatoes ripen faster than larger varieties, so you may start harvesting in mid-summer.
Harvesting Potatoes
Potatoes are ready about 10–12 weeks after planting, or when the foliage starts to yellow and die back. Carefully dig around the base of the plant with a small trowel to avoid damaging the tubers. Let the potatoes dry in the sun for a few hours before storing.
Storing Your Harvest
Store tomatoes at room temperature for the best flavor. Potatoes should be kept in a cool, dark, dry place. Avoid refrigerating potatoes, as cold temperatures can convert their starches into sugars, affecting taste.
Common Challenges and How to Solve Them
Even with the best care, pomato plants can face issues. Here’s how to troubleshoot.
Yellowing Leaves
Yellow leaves can signal overwatering, nutrient deficiency, or disease. Check soil moisture and adjust watering. If the problem persists, test the soil or apply a balanced fertilizer.
Few or No Tomatoes
This could be due to insufficient sunlight, poor pollination, or too much nitrogen. Ensure your plant gets enough sun and consider hand-pollinating flowers with a small brush if grown indoors.
Small Potatoes
Small tubers may result from overcrowding, poor soil, or early harvesting. Make sure your container is large enough and harvest only when the plant has fully matured.
Is the Pomato Plant Right for You?
The pomato plant is a fun, productive addition to any garden—but it’s not for everyone. It requires consistent care and attention, especially in terms of watering and feeding. If you’re new to gardening, start with easier plants like spider plants or polka dot plants to build confidence before tackling grafted hybrids.
That said, if you enjoy experimenting and want to grow more in less space, the pomato is a fantastic choice. It’s also a great conversation starter—imagine showing off your dual-harvest plant at your next garden party!
Final Thoughts
Growing a pomato plant is more than just a gardening project—it’s a delightful adventure that rewards you with two crops in one. Whether you’re short on space, love novelty plants, or want to teach kids about nature, the pomato delivers fun and flavor in equal measure. With the right care, sunlight, and a little patience, you’ll be enjoying homegrown tomatoes and potatoes by season’s end.
So why not give it a try? Grab a grafted pomato plant, a large pot, and some quality soil, and get ready to double your harvest fun. Your taste buds—and your garden—will thank you.
