Description
The pumpkin is the great spectacle of the autumn garden and delivers everything from soup fruit to giant. ‘Hokkaido’ tastes nutty and can be cooked with the skin on, ‘Atlantic Giant’ becomes a record attempt. It needs plenty of space, sun and nutrient-rich soil, preferably right on the compost heap.
Care instructions
Raise it from April (week 16) indoors or sow it after the ice saints (mid-May, week 20) directly into the warm bed. Water generously at the root, never over the leaves, because it is a thirsty heavy feeder. Lay ripening fruits on a board or straw so they do not rot from below, and harvest before the first frost.

legume family (Fabaceae)
Beans and peas enrich the soil with nitrogen, which cucurbits, as heavy feeders, can make good use of.

Rather not
nightshade family (Solanaceae)
You should avoid planting potato and cucumber together because they share disease pathogens such as leaf and brown rot and stand in each other's way as strong feeders.
