Frequently asked gardening related questions
Understanding your soil's pH (acidity or alkalinity) is fundamental for choosing the right plants and ensuring their health. The pH scale ranges from 0 (very acidic) to 14 (very alkaline), with 7 being neutral. Most garden plants prefer a slightly acidic to neutral pH (around 6.0-7.0). The easiest way to determine your soil's pH is by using a soil testing kit, readily available from garden centres or online. These kits usually involve mixing a soil sample with water and adding a chemical indicator, which changes colour to reveal the pH. You can also observe indicator plants: rhododendrons, camellias, and azaleas thrive in acidic soil, while plants like lavender, clematis, and delphiniums prefer alkaline conditions. Once you know your pH, you can choose suitable plants or amend the soil (e.g., adding lime to raise pH, or ericaceous compost/sulphur to lower it).
