These are my Cabbage, Lettuce and Turnip that are about half grown and I decided to give them a treat. My Beetroot and Brussels also got the same treat.
First I added a light side dressing of blood and bone at about a hand full per sq/mtr.
Then a side dressing of compost. I used about a bucket per sq/mtr
And then I covered it all over with my mulched prunings, again about a bucket per sq/mtr.
