It worked very well. (Using it reminds me of my mother's old washing machine which was woman powered by a rotating handle on the top.)
A wheel-barrow full of compost later....
18 Kestrel in two rows in bed 6 next the brassica tunnel and 6 in a small raised bed.
Method for bed 6: ditch along each long side, soil piled in middle, some potato fertilizer sprinkled in the bottom, seed potatoes about 18 inches apart. Then a shovel of sieved garden compost for each potato. The soil from the ditch will be replaced as the potatoes grow (said she confidently).
Method for the raised bed: as it is only half full of soil I just dug a hole, mixed the bottom soil with fertilizer,and put the seed potato in. Then a shovel of garden compost for each hole. I will earth them up with the soil improver which is being delivered next week.
I would've put a picture up, but I forgot AGAIN to take the camera or phone, and a picture, now they are planted, would be just a bed of soil, which I am sure you have seen before.
Later... Just to keep everybody happy, a picture of a bed of soil.
