Each square toes is planted with 1 , 2 , 4 , 9 , or 16 individual crops , count on their ripe size . For example , one grid might hold one Brassica oleracea italica plant , 2 cucumbers , 4 electric-light bulb onion , 9 spinach plants , or 16carrots . Tall plant are trellised on the north side of the garden bottom to avoid shading smaller plants . Once a grid or “ square ft ” is harvest , another crop is planted to take its lieu , creating time of year - long production .
Square Foot Gardening incorporates many of the value ofcrop rotationandcompanion planting . Once a plant pass on adulthood , it ’s harvest and that grid is planted with a dissimilar vegetable or herbaceous plant ( craw rotation ) . Different plants grown in gamy density create a polyculture , which is thought to have positive impacts on pest and disease resistor ( companion planting ) . It also creates living mulches and suppresses dope ( thickly planted crop fill in out weed seeds ) .
