How to grow

Plant seeds according to packet spacing and depth recommendations. Most varieties prefer full sun and well-draining soil. Squash, corn, and zucchini thrive in warm temperatures, while asparagus and Brussels sprouts benefit from thoughtful long-term planning. Water consistently during dry spells and support taller plants as needed. Pick zucchini and summer squash at the tender 6 to 8 inch stage, and harvest Brussels sprouts after a light frost for improved sweetness.

Flavor profile

Sweet corn and summer squash grill up sweet and tender, Brussels sprouts sweeten after frost, zucchini stays mild and savory, asparagus is grassy and fresh, and bunching onion adds a light, sharp finish.
