I’ve got wonderful Devon clay, it’s been improved over the years using dung and compost. But deeper down I still have poor drainage, Although the winter was wet the spring and summer in my area has been a good growing season. I only plant a few rows of Rocket spuds, I got one part row to dig. The last two rows have some slug damage but I’ve had worst. Around here farmers first cut was 50% up on some years, also hedgerows full of fruit and nuts. So is this nature preparing for a harder winter, we shall now more about that next spring.
