Brussels Sprouts ‘Abacus’ F1 (Brassica oleracea)

A replacement for ‘Diablo’ and in our trials here has proven to be just as impressive. These are the best Brussels Sprouts strain I’ve ever grown and I’ve tried twenty or so. Abacus produces crops over a long period from late autumn through most of the winter if seeds are planted no later than November. Later plantings are not worthwhile.

When to sow: Mid October-November
Where to sow: Seed trays, pots or outside seed beds.
Depth to sow: 5mm
Aspect:  Full sun or as sunny a spot as possible.
Soil:  Prepared, well drained, fertilised soil. Add lime if soil is too acid.
Spacing:  Between plants  40-60cm
  Between rows 80-90cm
 

Directions: Mid October to early November is the best and really the only time to plant Brussels Sprouts seeds either in seed trays, pots or outside seed beds. Any later planting is more than likely to end in disappointment. In windy areas staking may be necessary. When harvesting break off the leaf below the sprout and snap off the sprout. Plant seed no later than November and transplant to permanent position by early January at the latest.
