What Grows Well In Alkaline Soil

What Grows Well In Alkaline Soil

Different soils have different properties that should be considered when growing different things in them.

In this short guide, we outline what might grow well in alkaline soil.

 

Characteristics Of, & Profile Of Alkaline Soil

Alkaline soils:

  • Have a pH over 7
  • Can contain limestone or some type of calcium/lime rock deposit underneath the soil
  • Chalky soil is usually alkaline

 

Working With, Amending & Improving Alkaline Soil

Alkaline soils can be amended or balanced to come back to neutral, or become more acidic, with the additions of acidic fruit compost scraps, or elemental sulfur, or peat moss.

The addition of ash or lime will make soils more alkaline if you have acidic soils.

Note that there are differing levels of alkaline soil. Some plants for example may grow in slightly alkaline soil (just about 7), whilst some might like more alkaline soil. So, pH range does matter. 

You can test pH with a simple pH testing kit you can buy online or at the local gardening or home/outdoors store. You can also get soil professionally tested.

A Note On Soil Types, & What Ultimately Impacts How Things Grow

Before we look at what grows well in alkaline soil, it’s important to note that all soils are slightly different in composition depending on the location, there are different external factors acting upon each soil, and ultimately, there are many physical, chemical and biological factors that determine how well something grows in a particular spot or under particular conditions.

This is just a guide on alkaline soils in general, without going into extreme depth about all these other factors (factors like soil fertility, soil health, soil quality, fertilizer added, top soil added, pesticides added, tilling practices and so on).

It would do you well in the long term to get information on the type of soil in your location (what it is and what is the best way to manage it), the pH, the climate in your location (temperature, rainfall etc.) and the growing seasons (for example – the US has different planting zones), the plants or things you want to grow and the conditions they need – and come up with a specific plan for your situation.
