Hi all.
I know there was a bit of banter recently about covering clay or bad soil with some manure for the year. I did it last year and the soil this year is 2000% better and dug easily. I only did 1/3rd of each plot though, and this year doing another 3rd of each, and going 1 step better and planting gourds in it. I did some yesterday and today so thought I'd share it with you all :)
Sooooo I dug 12" cubed holes, 2ft apart in all directions (for courgettes first - I know its a bit close for pumpkin & squash but I might stick to it anyways and limit the fruits). I filled these with manure and soil mixed to make a low mound. It took 1 barrow to do the 4 holes (big barrow well rotted manure).
Then I just barrowed manure to mulch all around. Took 3 or 4 barrows. I will make a big hole in the top of each mound and fill with potting compost to stick the seeds in (as I couldnt start them at home - no room). As the soil is just too sticky to germinate a seed in.
This is the soil that I tried digging which I am covering with the manure. I dug this bit about a month ago and have looked after it just like I do any other bit. But it goes rock hard a day after any rain. Breaking it up was almost impossible - actually today while digging the holes, I bent the end of a spade only stuck in 1/2 a spit - its rock hard clay!!).
This is the soil I had covered with manure last year and left practically idle. I got a big flush of annual weeds (probably from the manure) but there was no more perennials than there was before manuring IMHO.
As you can see the difference is remarkable!!! So I personally recommend it. I suspect I will need to top it up mid-late summer, because of the squashes (which I will break up and mulch over end of season). But its free and improves the soil much better than carpet or plastic!
