1. What is the Compost Calculator For Pots?

The Compost Calculator For Pots helps determine the amount of compost needed for potted plants based on the pot's volume and the desired compost fraction.

2. How Does the Calculator Work?

The calculator uses the compost equation:

Where:

• \( \text{pot\_volume} \) — Volume of the pot in liters
• \( \text{compost\_fraction} \) — Fraction of the pot volume to be filled with compost (typically 0.2-0.5)

Explanation: The equation calculates the volume of compost needed by multiplying the total pot volume by the desired compost fraction.

3. Importance of Proper Compost Measurement

Details: Using the right amount of compost ensures proper plant growth, prevents over-fertilization, and helps maintain soil structure.

4. Using the Calculator

Tips: Measure your pot's volume accurately. Common compost fractions range from 0.2 to 0.5 (20%-50% of pot volume).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical compost fraction for pots?
A: Most plants do well with 30% compost (0.3 fraction), but this can vary by plant type.

Q2: How do I measure pot volume?
A: For regular shapes, use geometric formulas. For irregular pots, fill with water and measure the water volume.

Q3: Can I use 100% compost in pots?
A: Not recommended. Pure compost may retain too much water and lack proper aeration for roots.

Q4: Should I adjust compost amount for different plants?
A: Yes, heavy feeders may need more compost, while succulents typically need less.

Q5: How often should I refresh compost in pots?
A: Typically annually, or when repotting. Some fast-growing plants may need more frequent refreshment.
