When you chose plants for your garden the best way to increase your or your plant’s chances of success is by following the rule ‘Right plant, right place’. What does ‘right place’ mean? Well, it is a combination of things: soil pH, soil type, amount of sun, temperature, amount of space, climate, aspect etc. Seems like there’s a lot to understand about ‘place’ so let’s start with soil pH.
When planting in the soil in your garden you need to know is the soil acid or alkaline. You can measure how acid or alkaline your soil is with a pH tester. Soil with a pH of up to 7.0 is acidic and a pH above 7.0 indicates alkaline soil. The RHS website has more information about soil pH and how to measure it: www.rhs.org.uk/soil-composts-mulches/ph-and-testing-soil.
Plants that like more acidic soils are things like rhododendrons, azaleas, camellia, heather and magnolia. Whilst plants that like more alkaline soils include things like ceanothus, syringa/lilac, forsythia and lavender. (Neither of these lists are definitive, there are 1000s more!).
If you don’t want to rush out and buy a pH test kit just yet then have look at your soil type. Chalky soil will be more alkaline whilst clay soil will be more acidic. And I’ll talk about soil types in another post🌱.
When designing and planting your garden, you need to know whether the soil is acid or alkaline, as different plants thrive in different soils. The soil pH is a number that describes how acid or alkaline your soil is. A pH of 7.0 is considered neutral. An acid soil has a pH value below 7.0 and above....
