Calculadora de Cobertura Morta (Mulch)

The Mulch Calculator helps determine the exact amount of mulch needed to cover a garden area. Simply enter the area in square meters and the desired depth in centimeters. The calculator converts depth to meters, multiplies by the area to get volume in cubic meters, then divides by the bag volume (also in cubic meters) and rounds up to tell you how many bags to buy.

This tool is useful for gardeners, landscapers, and anyone applying mulch to flower beds, vegetable gardens, or around trees. Mulch helps retain moisture, suppress weeds, and regulate soil temperature. With the calculator, you avoid buying too much or too little material, saving time and money.

Important precautions: measure the area accurately, especially if the terrain is irregular. Recommended mulch depth ranges from 5 to 10 cm, depending on the material (pine bark, straw, etc.). Too deep can smother plants, while too shallow won't control weeds well. Always check the actual bag volume, as it may vary by manufacturer.

For irregularly shaped areas, divide into smaller rectangles or circles and sum the volumes. The calculator assumes a flat surface; on slopes, mulch may wash away, requiring adjustments. Use quality material free of weed seeds for best results.
