I have been growing potatoes very successfully for a couple of years now, and how do I do it? I grow them in old tires. Yes tires! Good old tires – It does not get greener than that!
Here is how it works:
You can cut your potato in pieces, make sure each piece has a least 3 eyes, let them dry a few hours and then you are ready to plant.
You will need 2 to 3 tires of the same size per plant (where to get tires? I got 2 of mine from a neighbor who just changed hers, and the following year we needed to change the tires of our car so I got 4 more. Ask around, a lot of people do have unwanted tires in their garages. You can also go to a local tire center and ask if they can give you a few)
Place your first tire in the ground and add a layer of good planting soil inside the tire, you can also put some small stones to add drainage.
Put your potato seeds inside 4 to 5 per tire, no more.
Cover the potatoes with another layer of soil. Water and wait.
In a few days you will see the potato plants sprouting out of the soil. Every other day you will take more soil and cover the plants leaving only one set of leaves out. Keep doing this until the tire is full of earth and the plants are poking out again. At that time, stack a second tire on top of the first and repeat the process again. You can do a third tire if you wish. Remember the potatoes grow on those stalks that you are covering up all the time.
I will be posting photos of the process as my potatoes grow so you can see it.
After about a week - you can see the potato plants coming out!
Here is a list of following posts throughout the season so you can see the whole process working!
