This cool weather plant is usually grown as a fall crop. Waiting to start seeds indoors after many other crops are already in the garden and growing. The trick to the tastiest Brussels sprouts is the harvest them after plants have been subjected to a couple light frosts which helps reduce their bitterness. Start them indoors using the same techniques as other Cole crops, with pre-moistened starting mix in trays or individual Jiffy® peat pots on top of heat mat with consistent 75°F bottom heat. Harden them off in time to get them planted into the garden around the middle of June in zone 5. Brussels sprouts are typically a long crop, so simply adjust planting times according to your zone and location.
