We have grown a squash outside in the north east of England - he is called Pascal. Pascal is a magic squash plant as we have never ever planted any squash plants.

For a peat to form you don't just need wet conditions you also need stagnant conditions

When we say sphagnum carpet I am not sure that you are supposed to be able to pick it up and fold it. This year's Sphagnum pioneers at Hatfield form a mat that dries out and detaches in ephemeral ponds. @durhamearthsci.bsky.social

Spring reminder, as people start to think about gardening: NEVER buy compost with peat it in (inexplicably still on sale). If it does not say "peat free" in big letters, do not buy it. Peat is incredibly valuable in peat bogs, for rare biodiversity and as a carbon store. Don't put it on your garden!
