Potatoes are among the simplest vegetables to grow, but a step often forgotten or neglected is earthing them up. It is as simple as regularly drawing soil, straw, or other materials around the plants to encourage more shoots and tubers to develop. Yes, it is a bit of extra maintenance, but it more than pays off come harvest time.
This simple task goes by several names; depending on where you grow your crops, it may be known as earthing, mounding, or hilling up potatoes. No matter what you call it, it is a really important part of growing potatoes, as it gives you a better yield. If you bypass hilling up potatoes, you end up with fewer potatoes to harvest and are more likely to have inedible green tubers.
