When to Sow Purple Giant Beetroot Seeds

Indoor Sowing: Beetroot seeds can be started indoors or in a heated greenhouse at any time of year. Ensure the pots or modules are placed in a sunny location for optimal germination.
Outdoor Sowing: Sow seeds outdoors from late spring (April) to early summer (July) after the risk of frost has passed, and the ground has warmed.

Step-by-Step Guide to Growing Purple Giant Beetroot from Seed

Preparing the Seeds

Soak the Seeds: Place beetroot seeds in a warm water bath for approximately one hour before sowing. This softens the seed coat and maximises germination rates.

Sowing the Seeds Indoors

Choose the Right Containers: Use seed pots or modules filled with fine-grade compost or loose, well-draining soil.
Plant the Seeds: Sow the seeds 1 cm deep and cover lightly with compost. Water gently to settle the soil.
Provide Light and Warmth: Place the pots in a sunny location, maintaining a temperature of 15-20°C for optimal germination.
Germination Time: Seeds typically germinate within 7-14 days. Keep the soil moist but not waterlogged during this period.

Sowing the Seeds Outdoors

Prepare the Soil: Ensure the soil is loose, well-draining, and thoroughly worked. Avoid clumped or compacted soil.
Planting Depth: Sow seeds 1 cm deep in rows, leaving 30 cm between rows to allow space for growth.
Watering: Water the soil lightly after sowing and keep it consistently moist during germination.

Transplanting Seedlings

Timing: Once indoor-grown seedlings are 5 cm tall, they can be transplanted outdoors after the last frost has passed.
Spacing: Space plants 8 cm apart to give them ample room to grow. Gradually harden off seedlings before planting them outdoors.

Caring for Purple Giant Beetroot Plants

Watering: Keep the soil evenly moist, especially during dry spells, to promote even growth and prevent the roots from becoming woody.
Feeding: Apply a balanced fertiliser to the soil before sowing or transplanting to provide essential nutrients for growth.
Weeding: Regularly remove weeds from around the plants to reduce competition for water and nutrients.

Harvesting Purple Giant Beetroot

Roots: Beetroot is ready to harvest when the roots reach the desired size, typically between 6-12 cm in diameter. Gently lift the roots from the soil with a fork to avoid damage.
Leaves: Harvest young leaves as needed for salads or garnishes. Avoid removing too many leaves from a single plant, as they support root development.

Common Questions About Growing Beetroot in the UK

Can beetroot seeds be sown directly outdoors? Yes, beetroot seeds can be sown directly outdoors after the last frost, as long as the soil is warm and workable.

How often should I water beetroot plants? Water beetroot regularly to keep the soil moist, but avoid overwatering, which can lead to root rot.

What soil conditions are best for growing beetroot? Beetroot thrives in loose, well-drained soil enriched with organic matter. Avoid heavy clay soils unless amended with compost or sand.

How do I prevent bolting in beetroot plants? Ensure consistent watering and avoid sudden temperature fluctuations. Sow bolt-resistant varieties, like Purple Giant Beetroot, to minimise the risk.
