Harvest Timing: Asparagus is picked early; strawberries take over later, using space efficiently. Shade & Moisture: Tall asparagus ferns provide shade, helping strawberries keep soil moist and cool. Weed Control: Strawberries act like a mulch, reducing weeds. Space Use: They share space and resources, boosting garden productivity sustainably.
