My allotment is semi-nodig, I don't do any autumn or winter digging, and I cover beds with manure I collect from a nearby field whever I can. The only time I dig is to cultivate potatoes, plant out seedlings/young plants, and control my three worst weeds: bindweed, couch grass and creeping buttercup. The lockdown and exceptional weather has freed up spring evenings to work on my plot which I wouldn't normally be able to use due to commuting then having to cook an evening meal, and I have taken advantage by applying manure and controlling perennial weeds. One good thing I have noticed this year is that despite the arid weather, the condition of the soil is not bad, and is workable, despite being primarily heavy clay, so the application of manure every year is clearly having the effect of improving the soil. I understand there is a way to cultivate potatoes without digging.
