Strong plants produce good quality, solid stems topped with high quality medium sized heads of good flavour.
The heads mature in approx 80 days from transplanting and stand well for a longer harvest period.
Sow - April to May
Plant Out - May to July
Harvest - July to September
Where to Sow - Sowings can be made in trays or modules under glass at 13°C. Later sowings can be made into a seed bed in shallow drills 2cm (3/4") deep in short rows.
What to do Next - As soon as glasshouse seedlings show their first pair of leaves, prick off into trays 5cm (2") apart or thin modules to one seedling per cell. Gradually harden off before planting out, spacing plants 45cm (18in) apart between plants and 45cm (18in) between the rows.
Outdoor sowings should be thinned to 7-10cm (3-4in) apart, then once plants are 15cm (6in) tall , they can be lifted and transplanted to their final planting positions, spaced the same as detailed above.
Handy Tip - All Brassicas prefer to be planted into firm fertile ground to produce the best crops. Keep plants well-watered during very dry weather especially as heads start to form.
