Tips for improving garden soil

Poor soil grows poor plants. Unless you drew the lucky card and have a garden full of black gold, you’ll need to know how to improve soil. Improving garden soil is an ongoing process as the plants leach nutrients, leaving the soil inadequate for their needs.

Whether your soil is nutrient deficient, compacted, heavy clay or any other issue, here’s a little soil amendment info to get you started.

Soil amendment can be as simple as mixing in leaf litter or it can be as complicated as running drainage pipes.

The condition of your soil needs to be adequate for sustaining plant needs. Compact or hard soils are actually great for starting a lawn, as long as you add a little sandy topsoil if starting from seed. Plants like fruits and vegetables, however, need loose, nutrient rich soil with plenty of organic amendments added every year. There is no rule on the best soil for gardens, but there are some basic guidelines and some easy fixes.

How to Improve Soil

In most cases, the need for amending soil arises from having poor, compacted soil or nutrient deficient soil. Here are some general tips on improving your soil:

Poor, Compacted Soil

Dense, hard soil may be the result of construction or simply little ones running across it constantly in play. The depth of compaction is important to know how to deal with it. If you have very deep, hard areas, you may have to rent equipment to dig it up and loosen it. Loosen the soil to a depth of at least 12 inches for most plants and up to 2 feet for trees and larger specimens. Garden soil preparation by manually shoveling is usually sufficient in most cases. Once the soil is loose, you may need to add several inches of compost or fine bark to keep it loose and workable.

Mixing the Best Soil for Gardens

There isn’t an actual recipe for soil; however, it needs a good balance of macro-nutrients and micro-nutrients, should drain freely and have a balance of carbon to offset the nitrogen.

Acid and alkaline soils can be amended with lime to sweeten the soil and sulfur to increase the acidity. Wood ash and oyster shells also naturally make acidic soil more neutral. Test kits are available at most garden centers to see if your soil is high or low in pH.
