Find the multiplier for the number of plants needed based on rectangular or triangular pattern planting using centimetres for spacing of the plants.
You can use this multiplier to estimate the number of plants needed for an area in square metres.
Enter the amount of spacing required in the calculator. Plant spacing = 20 centimetres The multiplier for 20 cm plant spacing for rectangular pattern = 2.5. The multiplier for 20 cm plant spacing for a triangular pattern = 2.89. Square metres of area to be planted = 10m x 3m = 30 sq metre Multiply the 30 square metres by the multipliers to get the number of plants needed; 30 x 2.5 = 75 plants for rectangle pattern planting. 30 x 2.89 = 87 plants for triangular pattern planting.
