A: There are a lot of soil-testing kits on the market. A trip to your local garden centre should turn up some simple testing kits where the solution just turns yellow/orange for acid, green for neutral and a darker green for alkaline soil.
Have you thought about pH meters? They cost under £10 and can give an answer quickly - just stick the probe in the soil and watch the scale. To get a reasonably accurate reading, I would take several tests over the bed or border concerned.

Sally, about nine months or so ago, you recommended MO Bacter for the removal of moss from lawns. I thought you might be interested to know the results of my applications.
The application made at the end of March was a total failure and I thought it was a totally useless product. But I have since changed my mind and I can only put the initial failure down to the ground being too cold and, by the time the ground had warmed up, the product had leached out of the ground.
I received a partial replacement from the main distributor, DJ Turfcare in Dunsfold, Surrey, and made a second application. And now I can say the results have been quite spectacular.
It is an interesting product. It removed the moss and the grass thickened up dramatically. I did have a bit left over, so I applied a little more and I would suggest the minimum rate of application should be increased by 25 per cent.
