We’ve tested 27 composts, including top brands B&Q, J Arthur Bower’s, Levington, Miracle-Gro, New Horizon and Westland, to find the ones that will get your seeds and young plants off to the best start this spring.
We’ve tested composts every year since 1985 and never cease to be amazed by how much the quality varies.
This year, only four of the 27 composts we tested are good enough to be Best Buys. Some are such poor quality that only a third of our seeds came up and seedlings struggled to survive.
One brand dominates our list of Best Buys – but which one? And which peat-free compost do we recommend?
To find out which composts you can trust this spring – and which you should steer clear of – read the results of our latest compost trials.
