I started a no dig garden on bare soil last autumn with cardboard, manure, 10-20 cm straw. I didn't put on the final layer of soil and the straw is dry on top and only slightly rotting on the bottom. No sign of worms, only under the cardboard.
The broad beans and peas I have started in modules and planted so their base is on the soil are looking a bit straggly.
We are now in late spring. Is it still worth adding the top layer? Can I use garden compost or do I need to use topsoil?
