SOW
When to Sow Broccoli Early Purple Sprouting in the UK
Sow from April to June, transplanting sturdy young plants into their final positions in summer.
Use that window as a practical starting point rather than a fixed deadline. In colder or exposed areas, delay outdoor sowing and planting; in mild sheltered areas, the earlier end of the range may work. Tender crops should remain protected until frost risk has passed.
Sowing Indoors
Sow in modules or a protected seedbed and give seedlings strong light. Potting on promptly avoids the check to growth that can spoil cauliflower and other brassicas.
Sowing Outdoors
Sow Broccoli Early Purple Sprouting in a prepared seedbed or plant module-grown seedlings into firm soil. Protect young plants with fine mesh from the day they go outside.
PLANT
Spacing and Planting Out
Allow 45–60cm between plants. Firm the soil around roots so tall plants do not rock in wind.
Before planting outside, harden off indoor-raised plants over 7–10 days unless the crop is fully hardy and already accustomed to outdoor conditions. Water the planting hole or container first and avoid leaving young roots exposed to sun or wind.
SMALL SPACES
Growing Broccoli Early Purple Sprouting in Pots and Containers
This is possible in containers but not a tiny-pot crop. Use one plant per sturdy 30–40 litre tub at least 30cm deep, firm the compost well and stake tall plants in windy positions.
Container checklist
- Use drainage holes and raise pots slightly so surplus water can escape.
- Fill with fresh peat-free compost suited to edible crops.
- Leave a watering lip below the rim and check pots more often in sun or wind.
- Use a strong support at planting time if the mature crop will climb or become top-heavy.
CARE
Watering and Feeding
Water deeply during dry spells and never allow young plants to stall. A balanced feed at planting and an occasional high-nitrogen feed during leafy growth can help container plants, but avoid overfeeding near harvest.
Variety note: Net against pigeons and caterpillars, and keep cutting side shoots after the main spear is removed.
WATCH FOR
Common Problems
Cabbage white caterpillars
Use fine mesh supported above the leaves and check undersides for eggs. Repair gaps immediately.
Pigeons
Birds can strip winter brassicas quickly. Secure netting so birds cannot become trapped.
Clubroot
Stunted, wilting plants with swollen roots may indicate clubroot. Use clean compost in containers and rotate brassicas in beds.
PICK
Harvesting Broccoli Early Purple Sprouting
Cut purple spears from February to April the following year.
This is a long-season crop: allow six to twelve months, with harvest commonly arriving after winter. Harvest in the coolest part of the day where practical and handle produce gently. Regular picking encourages continued cropping in fruiting and cut-and-come-again plants.
GROW TOGETHER
Companion Plants
Lettuce or radish can be grown temporarily between young brassicas and harvested before the canopy closes. Strong-smelling companions do not replace mesh against caterpillars.
QUESTIONS
Frequently Asked Questions
Can I grow Broccoli Early Purple Sprouting in pots?
This is possible in containers but not a tiny-pot crop. Use one plant per sturdy 30–40 litre tub at least 30cm deep, firm the compost well and stake tall plants in windy positions.

This is a long-season crop: allow six to twelve months, with harvest commonly arriving after winter.
Why is my Broccoli Early Purple Sprouting not forming a crop?
Interrupted growth from dry soil, root restriction, loose planting, heat or late sowing is often responsible. Keep plants firm, evenly moist and moving steadily.
