Useful Tips

• Account for settling: Order 5–10% extra; soil compacts after watering and use.
• Irregular shapes: Divide into rectangles/triangles or average the depth.
• Bag size varies: Common bags are 1.5–2.0 ft³—match to your store’s size.
• Plan access: Bulk deliveries need driveway or tarp space for dumping.
• Drainage layer? Most raised beds don’t need gravel; focus on good soil structure instead.
• Moisture content: Wet mixes are heavier and can settle more after filling.
