There is a technique called Bastard Trenching. (see capital letters. Noun.) It's probably some down home countryside phrase. In the same way that Asparagus is called "Sparrow Grass" in Norwich.
Well, there's a website ,dear reader, that I regularly visit which is far more knowledgeable about vegetables than my happy little site. I've been advised by people on that site that what I've been doing is not double digging. Not even a little bit.
I fear I've lead you astray dear reader and for that I can only apologise.
Some calcification is required. Double digging involves digging a trench twice the depth of your spade head. That's the double bit I guess. Then you dig another double trench next to the first trench and fill the first trench.....You know what ? Here's a picture.
What I was doing was none of these things. Still at least I gave clear instructions so that those that know, were able to set me straight.
But I did your digging.
So, technicalities aside, if you like my style of digging and feel like adopting it for your own plot then I have provided a suitable hybrid name in the above title. Nothing flash or self titled. It's just so that when someone asks, you can tell them what you're up to. I dare you!
