Sweet potatoes are great items to include. For this, you get a stalk or a sweet potato top and push it into the soil. If successful, you can have a bucket-full of potatoes in one harvest period. What makes them great is that sweet potatoes don’t demand too much attention. All they need is the right soil with the right moisture.
Put the plant under sunlight and make sure the soil is loamy. Loamy soils result in healthy roots. If the roots grow with irregular shapes, then there must be something wrong with the kind of soil your sweet potatoes are growing in.
