Sow at a depth of approx.
0.78 inches (2.0 cm) and aim for a distance of at least
5.85 inches (15.0 cm) between Beetroot plants. Soil temperature should be kept higher than
13°C / 55°F to ensure good germination.
By our calculations, you should look at sowing Mammoth Red Mangel about 14 days before your last frost date.
As Mammoth Red Mangel is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
Pick small for table use, or let grow (up to 20-pounds) for animal feed.
