Allotment Items (Cherwell Heights OX16)

Image is borrowed from the internet; it’s not mine.

I just got my first allotment. It’s a bit of a disaster and needs a lot of work. Does anyone have any allotment type items: I don't need tools (except for something to cut the grass path without electricity) but thinking.
* Compost bin
* wood scraps to build beds, or bean poles
* fencing post stakes; because I cant cement fence posts into the soil
* wire mesh
* something to help things grow up (like an arch)

Im not entirely sure; very new to this but appreciate the helping start.
