1. What is the Plant Spacing Formula?

The plant spacing formula calculates how many plants can fit in one square foot based on the distance between plants. This helps gardeners and farmers optimize space usage and plant health.

2. How Does the Calculator Work?

The calculator uses the plant spacing formula:

Where:

• Spacing — Distance between plants in feet

Explanation: The formula calculates the inverse square of the spacing to determine plant density per square foot.

3. Importance of Plant Spacing

Details: Proper plant spacing ensures adequate room for growth, prevents overcrowding, and optimizes resource use (water, nutrients, sunlight).

4. Using the Calculator

Tips: Enter the center-to-center spacing between plants in feet. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the ideal spacing for common vegetables?
A: Tomatoes typically need 2-3 feet, lettuce 6-12 inches, carrots 2-3 inches.

Q2: How does spacing affect yield?
A: Too close reduces air circulation and increases disease risk; too far wastes space and reduces total yield.

Q3: Should I measure from stem or leaf edge?
A: Measure from center of one plant to center of the next (stem to stem).

Q4: Does this work for square foot gardening?
A: Yes, this is the fundamental calculation for square foot gardening layouts.

Q5: How to convert to metric units?
A: First convert cm to feet (1 cm = 0.0328 ft), or modify the formula to use meters.
