Compare cost and convenience
Best for:
Small areas, precise placement, easy transport
Best for:
Large areas, lower cost per yard, fast coverage
At 1.85 cubic yards, bagged mulch may be more convenient and avoids delivery fees.
Ideal Depth: 2-3 inches
Suppresses weeds while allowing water and air to reach roots. Going deeper wastes material.
Keep Away from Trunks
Leave a 3-6 inch gap around tree trunks and plant stems to prevent rot and disease.
Refresh Annually
Add 1-2 inches of new mulch each year as it decomposes. No need to remove old mulch.
Landscape Fabric First
For permanent beds, lay landscape fabric before mulching for superior weed control.

| Type | Cost | Lifespan | Best For |
|---|---|---|---|
| Wood Chips | $ | 1-2 yrs | General landscaping, paths |
| Shredded Bark | $$ | 2-3 yrs | Flower beds, slopes |
| Rubber Mulch | $$$ | 10+ yrs | Playgrounds, permanent areas |

Organic mulches
Wood, bark, straw, pine - decompose and enrich soil
Inorganic mulches
Rubber, stone - permanent, no decomposition
Mulch is an essential part of landscape maintenance. It suppresses weeds, retains soil moisture, regulates soil temperature, and gives garden beds a clean, finished appearance. The right amount of mulch depends on the area you need to cover and the depth appropriate for your mulch type. This calculator supports both rectangular and circular bed shapes, making it easy to plan for any garden layout.
For most garden beds and landscaping, a mulch depth of 2-4 inches is recommended. Two inches is sufficient for decorative stone or rubber mulch, while 3-4 inches is ideal for organic mulches like wood chips and bark that decompose over time. Avoid going deeper than 4 inches, as it can smother plants and prevent water from reaching the soil.
One cubic yard equals 27 cubic feet. A standard bag of mulch is 2 cubic feet, so one cubic yard equals about 13.5 bags. Buying mulch in bulk by the cubic yard is usually cheaper than buying bags — especially for larger areas.
Organic mulch (wood chips, bark, straw) typically needs to be replenished annually as it decomposes. You may only need to add 1-2 inches on top of existing mulch each year rather than starting fresh. Inorganic mulches like rubber or stone last much longer and only need occasional topping off.
