2013 Which? Best Buy composts for containersBest Buy composts for pots and hanging baskets
22 February 2013
We've tested 23 composts, including top brands B&Q, J Arthur Bower's, Levington, Miracle-Gro, New Horizon and Westland, to find the best for the flowers and veg in your pots and hanging baskets this summer.
We've tested composts every year since 1985 and never cease to be amazed by how much the quality varies.
This year, only three of the 23 composts we tested are good enough to be Best Buys. Some are such poor quality that plants struggled to grow.
All three Best Buys are widely available. And one is a cheap, peat-free growing bag.
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.
