Arugula goes to seed so quickly that it’s frustrating. But I read this great idea and thought I’d try it. After arugula flowers, and as it starts to seed, just make sure that the seed pods are above the soil where you want your greens to grow. Let it go to seed, then break open the seed pods and sprinkle the seeds on the soil. Perfect.
It worked really well. I tied my long spindly arugula up in loose knot to keep the seeds over the soil of the planter. You can see the new baby sprouts growing up among the mature leaves.
