There are various factors to consider when determining the best soil mixture for raised beds, but generally, the best starting point is a blend of topsoil, compost and organic matter.

Organic materials, the key ingredients for healthy soils, abound. You can add fallen leaves, garden debris, kitchen scraps, and even apples raked from beneath fruit trees to soil. Chop organic material directly into the top 2 inches of soil with a heavy bladed hoe and cover with mulch.

If you do have an issue with compacted soil, try amending it with compost. Avoid adding sand. Compost is a better fix. The organic materials both break up the soil and attract worms and microorganisms that will further break it down.

In general, with proper maintenance, the soil in a raised bed can last for many years. Here are some guidelines for how long raised bed soil can remain viable: Soil that is well-maintained and regularly amended with organic matter can last for up to 10 years or more.

Eventually, the plants will take all the nutrients from the soil—there is not an endless supply, even if you start with the best soil. That means you need to be adding compost into the mix frequently. Before planting something new, add a 1- to 2-inch layer of fresh compost to renew the nutrient base for your plants.

Organic matter, such as compost, is one of the best ways to amend garden soil. Not only does it improve texture and drainage, but it also adds nutrients naturally.

Whether deep or shallow, raised beds give a gardener a way to create ideal soil conditions on an even larger scale. While potting mix alone is too light for use in raised beds, creating a 50:50 blend of potting mix and Miracle-Gro® All Purpose Garden Soil will give just the right balance.

To re-wet, repeatedly sprinkle the surface lightly, making sure there is no run off. Covering the surface with a mulch such as straw, leaves, wood chips, or compost will also help. Eventually the soil will become moist enough to break up. A gentle, steady rain will also do the trick.

Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don't need more.

Raised garden bed soil needs special attention because, over time, soil settles in the beds. Regular compost applications help aerate soil and improve water-retention and drainage. Sowing cover crops and turning them will also help improve raised soil.

Add organic matter such as compost, peat moss or leaf mold is the best method to improve the soil. Compressing soil because of weight. Vehicles parked or driven over an area, construction activities and even places with a great deal of foot traffic can become compacted.

Soil compaction can cause many problems in the garden bed and result in plants not being able to access the beneficial things they need from the soil in order to thrive. Plants need water, oxygen, and nutrients from the soil, and they take that in through their root systems.

It can be dumped directly out of your containers and into established beds and borders. You can use it in raised beds or wherever your yard has holes or eroded areas.
