Most books I read on planting pototoes say they need earthing up -
however as I only have limited space I want to plant the rows closer
together which means I can no longer earth them up. To counter this I am
considering planting the seed pototoes deeper. This seems to make sense
to me (but I'm not a vastly experianced gardner!). Could anyone please
comment on this as a reasonable sensible technique - or do spuds really
have to be earthed up.

Thanks
