Premium Compost is an excellent choice when your existing garden or landscape soil needs additional organic material. It can be mixed into established garden beds, added when preparing new planting areas or applied around existing plants.

Rather than replacing all the soil in an area, compost can be incorporated into the soil you already have.

What Is Premium Compost Used For?

· Improving existing garden beds

· Preparing flower gardens

· Preparing vegetable gardens

· Adding organic material around plants

· Mixing into existing landscape soil

· Refreshing soil before a new growing season

Adding Compost to Existing Soil

Compost is generally mixed with existing soil instead of being used alone as a complete replacement for garden soil. The appropriate amount will depend on the current soil conditions, the plants being grown and the depth of the planting area.

If you are filling an entirely new garden or raised bed, one of our prepared soil blends may be a better choice. Our team can help you compare Premium Compost, Garden Blend, Raised Bed Soil and 3-Way Soil.

How Much Compost Do You Need?

Measure the length and width of the area and determine how deeply you plan to apply the compost. These measurements can be used to estimate the amount required. Contact us if you need help calculating the correct quantity for your garden or landscaping project.
