Plant Spacing Formulas

1. Plants per Square Foot

                        Plants/sqft = 144 / (Spacing in inches)²
                    

Example: 24" spacing = 144 ÷ (24×24) = 0.25 plants/sq ft

2. Plants per Acre

                        Plants/acre = 43,560 / (Space per plant in sq ft)
                    

Example: 24"×24" spacing (4 sq ft) = 43,560 ÷ 4 = 10,890 plants/acre

3. Plants for Rectangular Garden

                        Plants = (Length × Width) ÷ (Space per plant)
                    

4. Quick Conversions

• 1 acre = 43,560 sq ft

• 1 hectare = 2.47 acres

• Space in sq ft = Spacing² / 144
