Pomato (Tomtato)

Pomato: The Incredible Plant That Grows Both Potatoes and Tomatoes

Imagine picking fresh, juicy tomatoes from a plant and then digging beneath the same stem to harvest plump, starchy potatoes. Sounds like science fiction? Enter the Pomato – a marvel of modern horticulture and grafting ingenuity.

What is a Pomato?

The pomato (sometimes called a tomtato) is a grafted plant that grows tomatoes above ground and potatoes below ground. Both belong to the Solanaceae family – often called the nightshade family – which includes tomatoes, potatoes, eggplants, and peppers. While not genetically modified, the pomato is created through a process of manual grafting, uniting the shoot of a tomato plant with the rootstock of a potato plant.

This hybrid doesn’t occur naturally, but it’s a great example of what happens when science meets sustainability.

How Does It Work?

Grafting is an ancient agricultural technique where two plants are physically joined so they grow as one. In the case of the pomato:

The tomato shoot (scion) is cut and placed onto the potato rootstock.

The point of contact is sealed and nurtured until both grow together.

Over time, the tomato plant flourishes above, while the potato tubers mature below.

The result is one plant that gives you two crops – and saves space in small gardens.

Why Grow a Pomato?

1. Space Efficiency:

Perfect for urban gardeners, balconies, and small backyard spaces. One pot, two crops.

2. Educational Value:

Great for schools and plant lovers. It demonstrates plant biology, family relations, and grafting techniques.

3. Sustainability:

Double harvest means better yield with less soil, water, and fertilizer.

4. No GMO Worries:

It’s a natural union, not a genetically modified organism. Just smart horticulture.

Tips for Growing Your Own Pomato

Purchase a grafted plant or try grafting your own if you’re experienced.

Use a large container with rich, well-drained soil.

Support the tomato vines with stakes or cages.

Harvest tomatoes first; then carefully dig for potatoes at the end of the season.

Provide full sun, regular watering, and balanced nutrition.

Fun Fact

The idea of the pomato isn't just a novelty. It's being explored as a solution to food scarcity and urban agriculture challenges. Companies in the UK and New Zealand have even commercialized the plant under names like "TomTato".

Final Thoughts

The pomato is more than just a clever garden trick – it’s a symbol of innovation in agriculture, a creative response to limited space, and a practical teaching tool. Whether you're a gardener, a teacher, or just a fan of odd-yet-useful plants, the pomato is sure to impress.
