1st early spuds then sweetcorn

i dont think ya gonna get away with it matey but heres an idea for ya . get some black plastic sheeting .in maybe a yard wide now lay it out down ya garden  you may wanna fold it in half . now slit a hole every 12 inch or so and just scoop a little soil to one side  through the hole and pop ya tatties in through that bury the edges of the plastic or cover them with heavy fence post type wood . now leave a space between the next row of plastic and  when ya sweetcorn is ready to plant out ,put it direct in the soil between the rows of plastic covered tatties ,the tatties will sprout through the slit in the plastic sheeting and you can just plant your sweetcorn at the normal time
