Soil facts and preparation

Quick facts..

  • Soil Type Fertile and Well Drained
  • Ideal Ph range 5.5 to 7.0
  • Site Full Sun
Courgette plants require fertile, well drained soil with plenty of organic matter. Choose a sunny site and dig holes at least half a meter deep and 1 meter apart. Fill with well rotted manure or compost creating a slight hill.

Courgettes can also be grown in large containers filled with fresh compost sited in a sunny spot.

Sowing and planting

Quick facts..

  • Germination 5 to 10 days
  • Sow 25mm deep
  • Sow Spacing 1000mm
  • Rows 1000mm apart
Courgettes like warm soil and will not tolerate frosts. Do not be too hasty to sow outside to early in the season if you live in an area where spring frosts occur. You can of course start plants inside or in the greenhouse in 10cm pots or containers and then transplant.

Sow 3 seeds 3cm apart in each location or container and thin to a single seedling when approx 5cm tall. Cut thinnings at the base of the stem rather than pull them.

Growing a bumper crop

Keep weed free and water regularly, trying to keep an even moisture level in the soil.

When watering try to avoid wetting the leaves of the plant and water early in the day so the top of the soil dries out during the day. This will help prevent disease and mildew.

Mulching around the plant can help retain moisture in the soil. Use a dilutable liquid fertiliser once a week once the plant begins to flower.

Harvesting the fruits of your labour

Quick facts..

  • Yield 1520g per plant
Pick when the fruits are between 10cm and 20cm in length. Regular picking will encourage continual production of courgettes.

The plant will produce both male and female flowers, the female flowers base will swell to become a courgette. Both male and female flowers are edible and can also be used as a garnish to dishes.

Courgettes do not store well so consume within 3 days of harvesting.

Courgette varieties


A very heavy and early cropper, defender yields are nearly twice that of other courgette varities. Courgettes are dense, mid-green and solid and have a noticably good flavour. The plants will produce courgettes over a long period of time especially if harvested regularly when courgettes are small. The open habit of this variety enables easy access to fruits. Bred to be resistant to Cucumber Mosaic virus, defender is one of the most reliable varieties of courgette.


The Safari variety produces dark green courgettes with light green stripes. Plants have an open habbit making it easy to see and cut fruits from the spine free stems. A prolific cropper of tasty, eye-catching fruits from plants with silvery leaves makes this a worthwhile and novel variety to grow.


The uniformly shaped yellow fruits of the sunstripe variety have white stripes running length ways. This variety should not just be considered for its novel appearence, the flavour and texture are both great too. The plants are bushy and have an open habit making it easy to spot and pick the fruits. The leaves of the plant also have yellow markings and the stems are spineless so no scratches when picking. Regular harvesting of a single plant will yield in excess of 20 courgettes.
