containers (at least 30cm/12inches wide) or 2 per
growbag
Outdoors in open ground - 5cm/1" deep on its side at least
45cm/18 inches apart on all sides.
After Germination
Keep well watered. Protect from slugs.
Growing on -
in Containers
Harden off indoor sown plants then transplant singly large
containers at least 30cm/12" wide and deep or 2 per growbag.
Growing on -
in open ground
Plant out at least 60cm/2ft apart on all sides.
Aftercare
Pinch out growing tips of trailing varieties when they reach
60cm/2ft long. Keep very well watered but only water around
the plants and feed with liquid fertiliser once the fruits
begin to form.
Harvesting
Continual cropping is necessary to prolong the harvesting
period. Start cutting courgettes at about 10cm/4" and
