How to grow potato in water

In this post, we are going to learn how to grow potato in water for your science experiment project.

So, how can you grow potatoes in water? Let’s explore the step-by-step process:

1. Preparing seed potatoes

Cut the seed potatoes into smaller pieces, making sure each piece has at least one eye or bud. This will serve as the starting point for the new plant.

Or, just leave the potato in an indirect sunlight. After a few weeks, eye sprout should be visible on the potato.

2. Hold potato in place

Next, stick a few a toothpick on the potato so it stays in place in the container where the water can cover around two thirds of the potato

Maintain a consistent water level. Keep the container in a well-lit area with temperatures between 60-70°F

3. Transplant into container

In 1 or 2 weeks, the potato piece will develop roots and shoots, the it is ready to be transplanted into soil.

Choose a suitable container that is at least 16 inches deep with adequate drainage holes.

Fill the container with nutrient-rich soil, leaving a few inches at the top.

Plant the rooted potatoes in the soil, leaving a few inches between each piece if you plan to plant more than one seed potato. Keep the soil moist and fertilize regularly. Make sure the container is not waterlogged.

Harvest when the leaves yellow and die back. That’s going to take about 70 – 100 days.


The idea of growing potatoes in water may seem unconventional and even a bit strange at first.

However, it is a fascinating experiment that challenges our traditional notions of gardening.

While it may not be the most efficient or practical method for growing potatoes on a large scale, it certainly offers a unique and engaging way to explore the wonders of nature.

So, why not give it a try and see what surprises await you in your own potato-in-water gardening adventure?
