Globe artichoke 'Romanesco'

Romanesco is generally regarded as a half hardy plant, so it will need protecting in periods of cold weather. Romanesco needs a loamy and sandy soil with a ph of 5.6 to 6.6 (weakly acidic soil).

Try to ensure a gap of at least 1.95 feet (60.0 cm) when sowing to prevent overcrowding your seedlings. For optimal germination, soil temperature should be a minimum of 18°C / 64°F.

By our calculations, you should look at sowing Romanesco about 48 days before your last frost date.

Romanesco is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
