Mid-October to early November is the best and really the only time to plant Brussels Sprouts seeds according to Lambley Nursery so here we go! LAMBLEY NURSERY. https://lambley.com.au/plant/brussels-sprouts-abacus-f1-brassica-oleracea 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.
