Plant potatoes in the soil with the eyes facing up allowing for the plant to start growing quickly. Cover gently in soil. As the leaves begin to sprout over the top of the soil add more soil to encourage the plant to grow upwards creating new roots and potatoes as it goes. How are potatoes grown?
You see, when the weather is hot, the top part of the plant respires heavily, reducing the amount of food material that can otherwise be put into storage in the tubers below ground. This helps to explain that while potatoes may be a summer crop up North, they’re a late winter, spring or fall crop in the South.
The next thing we asked ourselves was: how do potatoes grow from cuttings?
One source stated when conditions are right, these buds will sprout, whether the potatoes are in the ground or in a kitchen cupboard. The sprouts then develop into independent plants. The cut potato piece or “seed” piece provides the new sprout or seedling with nourishment from its supply of stored starch.
This begs the query “What kind of potatoes can you grow from seed?”
This is what we learned. Use small but healthy potatoes for seed potatoes. If your seed potato is larger than a chicken egg, you can cut it in half or thirds. There should be at least two eyes or sprouts per piece. You can grow any variety of potato you like, but make sure you’re using spray-free potatoes that haven’t been treated.
The answer is that Potatoes do not grow on trees but are a root-like tuber that grows underground. Potatoes grow best in rich, soft, well-drained soil so they have room to expand. French fried potatoes (AKA fries) also don’t grow on trees.
The next thing we wanted the answer to was; can you grow potatoes from supermarket?
This is what my research found. This makes conventionally grown potatoes from the supermarket less than ideal for growing potatoes in your garden. Plant potatoes in the soil with the eyes facing up allowing for the plant to start growing quickly. Cover gently in soil.
You plant a whole, small potato, or a piece of a larger one for a new plant. The whole potato or cut piece has several slightly recessed, dormant buds or “eyes” on the surface.
How do they grow potatoes on Mars?
Mark Watney (played by Matt Damon) survives by fertilising Martian soil with his faeces, slicing up potatoes, and planting the cuttings in the soil. This eventually grows him enough food to last hundreds of days. Growing potatoes and other food on Mars is not just a sci-fi curiosity.
Some articles claimed it’s unlikely potatoes will ever be grown freely on the surface of Mars.
I discovered now, a NASA-backed “Potatoes on Mars” experiment is showing that Watney’s fictional feat might actually be possible.
Can potatoes grow in the shade?
Potato plants can grow in partial shade. However, they will grow best and produce more (and larger) tubers with some direct sunlight every day. Potato plants can grow in partial shade, but will do best with 6 or more hours of direct sun per day.
Here is what my research found. although potato plant leaves need light to grow, their tubers and roots do not need light. In fact, potato tubers will turn green and produce a toxic substance (solanine) when exposed to light. Potato tubers turn green and produce the toxic substance solanine when exposed to sunlight for too long.
How would Watney grow food on Mars?
Aside from bringing along an extra crop or two—say, some salad greens—he’d grow the plants using hydroponics instead of Martian soil, or regolith, as Watney does. Watney has no choices given the equipment on hand, but hydroponics would make it way easier to control the recycling of nutrients and water.
In “The Martian,” Mark Watney uses the Martian soil to grow potatoes in the controlled environment of the “Hab.” In reality, the soil on Mars actually does have the nutrients plants would need to survive on Mars!
