Dig a trench around 3 to 5 inches deep depending on the variety of potato.
Add a light sprinkling of horse manure to the trench before planting.
Plant early potatoes about 12 inches apart with 16 - 20 inches between the rows.
Plant second earlies and main crops about 15 inches apart with 30 inches between the rows.
With the shoots pointing upwards, cover the potatoes lightly with soil.
As soon as the shoots appear, cover each plant with a ridge of soil so that the shoots are just buried.
Do this at regular intervals until the end of the season.
Sow the seeds thinly on a sunny, dry day in shallow drills approx 1 inch deep and cover the seeds once in place.
Once the seeds have germinated and are showing their first rough leaves, thin the seedlings to 2 inches between plants.
The plants need little other attention during their growth period, although they should be kept well watered as too little water results in coarse, woody roots.
Set the sweetcorn plants 12 inches apart with 24 inches between rows to form a block.
Keep plants well watered and the soil weed free, taking care not to sever the surface growing roots of the sweetcorn.
Corn is ready when the silky tassels at the end of the cobs turn brown - but check this by peeling back the leaves and pinching a kernel - the juice should be milky.
Create a seed bed and sow one bean 2 inches deep and 9 inches apart.
Sow in double rows or blocks and stagger the plantings to make the best use of space.
As the plants grow you will need to stake them to prevent the fragile stems from bending or breaking.
When ripe, pick from the bottom up and continue to harvest frequently.
Add a sprinkling of horse manure to the soil to provide much needed nutrients.
By steeping some composted horse manure in water for around a week, you will produce a nutrient rich horse manure compost tea - ideal for using as a liquid fertiliser!
