When you’re not actively grwing veggies empty any rotted down compost from your heap (leaving the unrotten on the heap) and put a layer over your veg beds. Then watch the worms take it all down into the subsoil – they will do a fantastic job at breaking the matter down, aerating and improving the quality of the soil, leaving your bed ready and prepared for the following spring.
When you grow your own, you’re really a keeper of soil, which you grow plants on. I really don’t believe in digging over your veg plot – there is absolutely no need if you do as mentioned above.
