The primary challenge to using kura clover as a cover crop is that seeds are sometimes difficult to find, and farmers must exercise some patience as it grows.

“It’s a bit of a tortoise-and-hare story,” Baker said. “Kura clover puts much of its initial resources into roots and rhizomes (root systems that grow horizontal roots and shoots at various intervals), so initially it will look like the weeds have the upper hand. However, each time it’s mowed, the kura comes back stronger and, eventually, the grower is rewarded with a healthy, vigorous cover crop that can last for decades.”
