This afternoon's #allotment job was to work on the long raised beds on the polytunnel plot. First trenching along the edges then lining with plastic sheet* before levelling off. Next we will top these with as much compost as we can scrape out of the oldest bay (mainly year+ old horse manure) and then they're ready for planting.
These beds were part of the original design for the plot but for four seasons have just been long mounds as we didn't have timber for sides. The timber is spare from a deadwork building project, we put it in place at the end of last season. I've been wedged on doing fancy metal stability stakes for it for ages but finally just went with screwing it together as we need beds really soon.
Now their usable area will increase from about 50cm to over a meter, should double the productivity! 
* plastic sheet/membrane also left over from deadwork, I wouldn't buy it for the purpose but I'll use it if it's effectively free and surplus.
