I'm keen to learn but I don't quite get what you mean by them not liking to follow immediately after sod. Pls explain. Is it to do with putting in horseshit too early?

I've been wondering about what I could add to the potatoes by way of nutrients, and indeed if I need to. I've got some 'compost juice' (liquid veg matter) which I'll add to the water once the earthing up is over.

Thanks for commenting. I appreciate any thoughts or pointers from you as I'm sure you will have plenty of experience :D.
