Sweet Potato Plants & Seeds Good sweet potatoes start with good seed. Sweet potato seed has to be updated constantly because it loses quality rapidly from one year to the next. Viruses can quickly infect an entire crop, resulting in low yields, poor quality, and misshapen roots. Jones Family Farms is one of only a few farms in the world that grow micropropagated, virus-indexed plants for sweet potato production. Micropropagation involves eliminating all viruses that may affect the growing potential of a sweet potato plant. This is not a genetic alteration in any way. This process simply brings the plant back to its original state-free of all viruses and other afflictions. Virus-indexed plants mean amazing yields, uniform roots, and outstanding storage capabilities. This program was created so commercial growers could obtain better seed stock, thus producing higher-quality sweet potatoes on less acreage. Whether you are a commercial grower or just need a few plants for your garden, Jones Family Farms can provide you with the plant you need to grow a better sweet potato.
