Ah.......I think differently with great respect.
Initially dug ground is ready for deeper rooting stuff. Besides when I trench in I also put as much throughout the layers to the top. There is a difference between burying compost a spit or so deep and mixing it in.
Another point of disagreement LeifUK is that compost on the top makes soil COLDER in spring. It holds more moisture....wetter soil is colder soil. It shields the soil from the early warming rays of spring sun. to support my own conviction I Have found mulched plants are slower to show in spring. Mulched soil is cooler in SUMMER too....an advantage in a hot dry summer
A poor soil a few inches below a heavily mulched one can never be as deeply enriched as one prepared a spit or more deep. my carrots,for example, are long rooted....not those roots on the show benches but EDIBLE roots. Rhubarb too....loves the deep rich soil. Try rhubarb on a poor soil but heavily mulched for proof.
Worms populate the soil better in deeper spoils...they survive better in the lower levels in winter
whilst the soil surface is GRADUALLY being enriched over the years by mulching an initial digging cuts this time by several years
LeifUK I think out my methods,,experiment and compare. Always aiming for better plants whether they be edible or ornamental
but, this is the FUN of gardening, Isn't it? No one way is right. We all have different systems and can argue....debate....the pros and cons all day long. I respect every point of view
