Do not underestimate the amount of time and effort that you need to put into an allotment.
Other allotmenters will generally be very useful and handy with advice.
The tools you will need:
Spade
Fork
Hoe (dutch)
Watering Can
String
Bamboo Canes
If they have a communal compost heap that is very useful, otherwise you might want to get your own small one on your plot.
