Growing media sales volumes are well down this week, and only marginally better than the same week in 2014 and 2013. It’s been an almost perfect autumn for potting and planting so far in most parts of the UK but temperatures are dropping and more frequent frosts over the next two weeks may well put the brakes on demand even further, althohugh gardeners may be waiting until the frosts before clearing out their summer containers to make way for their winter and spring plants.

• Westland Landscape Bark (100 litres) is the highest climber, up 15 places in the chart.
• Scotts Levington Organic Choice Top Soil  (25 litres) shows a gain of 13 places,and so does Growise MP Compost (50L).
• Scotts Miracle-Gro  Eco Sense Bulb Compost climbs 10 places as bulb sales pick up now that summer containers are finally going over.
