Description
The courgette is the most generous plant in the summer garden: a single plant supplies a whole family and delivers tender fruits continuously from high summer until frost. Harvest it young at about 15 to 20 cm; look away for a few days and you quickly find a giant club.
Care instructions
Raise it from April indoors or sow it after the ice saints (mid-May, week 20) directly into the bed in a sunny, nutrient-rich spot, ideally on the compost heap. Water generously and always at the root, never over the leaves, to prevent mildew. Harvest regularly, because every fruit left standing slows the supply of new ones.

Feeding

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

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.
