Look to ensure a distance 11.7 inches (30.0 cm) between Blackthorne seeds when sowing to make sure your seedlings have enough space.

By our calculations, you should look at sowing Blackthorne about 42 days before your last frost date.

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