FAQs

What is the main advantage of 'Resistafly' F1 Hybrid carrots?

The primary advantage is its good resistance to carrot root fly, which helps ensure a higher yield of undamaged, tasty carrots.

How far apart should I thin the carrot seedlings?

Thin seedlings to approximately 5cm (2 inches) apart once they are large enough to handle. This allows adequate space for root development.

Can I grow these carrots in containers?

Yes, Carrot ‘Resistafly’ F1 Hybrid can be grown in deep containers or troughs, provided they have good drainage and are filled with a suitable compost.

When is the best time to sow Carrot ‘Resistafly’ seeds?

You can sow outdoors from April to July for a continuous harvest. Early sowing under cloches is possible from March, and maincrop sowing runs from April to June.

Why is it important to prepare the soil in autumn?

Preparing the soil in autumn allows it to settle and avoids the use of fresh manure, which can lead to excessive leaf growth and potentially forked roots instead of well-developed carrot roots.

How long does it typically take for the seeds to germinate?

Germination usually takes between 10 to 20 days, depending on soil temperature and moisture levels.

What is the expected height and spread of the mature plants?

The carrot plants will reach a height of up to 30cm (12 inches) and spread up to 15cm (6 inches) when fully established.

Troubleshooting

Poor germination

Ensure seeds are sown at the correct depth (1cm), soil is consistently moist during germination, and within the recommended sowing dates. Very old seed may have reduced viability.

Forked or stunted roots

This is often caused by inconsistent watering, compacted soil, or growing in soil with fresh manure. Ensure soil is loose and well-drained, and water evenly.

Green crowns on roots

This occurs when the top of the root is exposed to sunlight. Lightly earth up the soil around the base of the plants as they grow to cover the crowns.

Pest damage (e.g., slug holes)

While resistant to carrot root fly, other pests may still be an issue. Use appropriate slug deterrents or netting if necessary, and maintain healthy soil conditions.

Pros and Cons

Setup, Compatibility & Care

Sowing Instructions:

  1. Soil Preparation: Choose a sunny position with fertile, light, well-drained soil. Prepare the seed bed well in advance, ideally in autumn, to avoid fresh manure which encourages leafy growth over root development.
  2. Sowing Time:
  • Early Varieties: Sow under cloches in March, or outdoors from April to July.
  • Maincrop Varieties: Sow outdoors from April to June.
  • Forcing Varieties: Sow under glass from November to February.
  1. Sowing Method: Sow seeds thinly, 1cm (½in) deep, in drills spaced 30cm (12in) apart.
  2. Germination: Expect germination in 10 to 20 days. Water well to encourage this initial stage.
  3. Thinning: Once seedlings are large enough to handle, thin them within each row to about 5cm (2in) apart. This is crucial for allowing roots to develop properly.

Care:

  • Watering: Water only when necessary to keep the soil moist after germination. Avoid overwatering, which can promote leaf growth at the expense of roots.
  • Earthing Up: As the roots grow, earth them up slightly to prevent green tops (crowns) from developing.

Compatibility: Suitable for direct sowing outdoors, under protection (cloches/glass), and in containers.
