Ensure that your soil's pH level is 6.5 or lower. Three tires are needed to maintain a proper height for growing potatoes. Let's begin with the procedure now.
If all the tires are not of the same size, determine which is the biggest and lay it down first. This acts like a base. Now, fill the tire with soil. Plant your potato seeds in this tire, keeping a little distance between each chunk. Plant a maximum of three chunks.
Add another tire and lay the soil around the stalk once the plant is around 8 inches tall. To avoid suffocation of the plant, leave a few inches uncovered. Repeat this process after the shoot grows 8 inches further. Don't place all the tires at once.
Now that you have planted the potatoes, water the taters well and ensure a thorough drainage of water. Water the seeds a bit more than usual immediately after planting, when it is in the flowering mode. If possible, do this in the morning, because if the leaves stay damp overnight, they are more prone to diseases.
By the end of summer, when the foliage would turn brown and die back, stop watering. The harvest time has not yet arrived; there is still time for potatoes to be ready. Before the commencement of the initial showers of rain, harvest the taters, or else they would rot in the ground. Post the procedure of gigging them up, keep them in a dry place.
Watering the plant regularly in the mornings is very important. The first time you grow potatoes, it might be a little difficult to gauge the watering time, the soil adding time, and the harvest time. However, the second time onward, you'll know exactly what you're dealing with.
