I am very excited at being given a 1/4 plot after waiting 3 years for an allotment. There are some raised beds already in place and I wondered if its too late to be getting manure and putting on the beds, i don't really know what the soil is like and it has been snowing so cant really get started yet! I tried to grow potatoes last year at another allotment i was sharing and they were very dissapointing, just not very many. I didn't prepare the ground very well. What do potatoes need to do well? Any advice very welcomed.
