Enter the total number of plants and the total area (ft^2) into the Calculator. The calculator will evaluate the Plants Per Square Feet. 

Plants Per Square Feet Formula

PLSF = P / A

Variables:

  • PLSF is the Plants Per Square Feet (plants/ft^2)
  • P is the total number of plants
  • A is the total area (ft^2)

To calculate Plants Per Square Feet, divide the total number of plants by the total area.

How to Calculate Plants Per Square Feet?

The following steps outline how to calculate the Plants Per Square Feet.


  1. First, determine the total number of plants. 
  2. Next, determine the total area (ft^2). 
  3. Next, gather the formula from above = PLSF = P / A.
  4. Finally, calculate the Plants Per Square Feet.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of plants = 100

total area (ft^2) = 12

FAQ

What factors should be considered when calculating plants per square foot?

When calculating plants per square foot, consider factors such as the mature size of the plants, the growth habit (upright, spreading, etc.), the sunlight requirements, and the soil conditions. These factors will help ensure that plants have enough space to grow and thrive.

Can the plants per square foot formula be used for any type of plant?

Yes, the formula can be applied to any type of plant, but it’s important to adjust for specific needs of different species, such as spacing requirements for optimal growth. Some plants may need more space than others to reach their full potential.

How does calculating plants per square foot help in garden planning?

Calculating plants per square foot helps in garden planning by ensuring that the space is used efficiently, preventing overcrowding, and promoting healthier plant growth. It also assists in estimating the number of plants needed to fill an area, which can help with budgeting and purchasing.

Is there a difference between calculating seeds per square foot and plants per square foot?

Yes, there is a difference. Calculating seeds per square foot considers the germination rate and the thinning process, as not all seeds will germinate and some seedlings will be removed. Calculating plants per square foot focuses on the space needed for mature plants. Both calculations are important for different stages of garden planning.
