Acidic remarks?

Have your say

KNOWING the pH of your soil is vital to what you can grow.

I’m ashamed that I hadn’t bothered to do this before – I tried to grow a rhododrendron years ago and it was a failure.

This genus (plus azaleas, hydrangeas and heathers) are acid-loving plants, which hate lime, so I guessed my soil must be neutral or slightly alkaline.

I was right. Using a small pH test from the garden centre, it’s easy to take a sample, mix it with the chemicals and compare the resulting colour with the chart.

As you can see, my soil is pH 7 (neutral), which is an all-round decent ph for most things.

However, if you want to grow lime-haters, use ericaceous compost in large tubs or raised beds.
