I just wanted to give you a update on how the potatoes are doing and on the instructions on how to add the second tier of tires.
|Before adding soil|
|After adding soil|
As the potato plants start to grow in the tires you need to start adding soil to the hole, covering the stalks as this is where the potatoes will grow. You should leave only a leaf or two and wait until they grow some more.
|Full first tire|
At some point, the first tire will be completely full of earth, then you should wait until the plants are about 6 inches tall until it is time to put the second tire.
|Second tire stacked carefully|
To do so, simply stack one tire on top of the other, being careful not to crush the leaves while doing so.
Once the tire is in, start putting soil and covering the stalks again as you did with the first tire, and repeat the whole process as you did with the first tire.
Once the second tire is full, you can add a third tire or leave the plant to mature with only 2 tires. Your choice depending on how many potatoes you want to eat!
