Try sowing in modules and then planting them out. Something must be eating the seed because it should germinate fast and easily.

go buy some young plants.. and plant them ... asap.. subject to current heat wave ...

im not sure you have enough season left to start and finish these long season plants in the midwest from seed .... i know they are supposed to be left out thru the first frost or freeze for best flavor . but crikey.. you have to have mature sprouts on the plant in october to do that ...

i think these should have been sown outdoors in early april... but i might be wrong on whether these are the type of plants that the seed can be planted in cold spring soil ...just bringing up the planting time.. i would defer on this part ...

Thanks, I never have a problem with growing season here, I just might not get as many.

understood .... but do you have another month to wait to see if seeds may or may not sprout????

May be you have a batch of expired seeds?

I would think that now is a really bad time to attempt to grow Brussel sprouts. They are a cool season crop that struggles in summer heat. Even in my very cool summer climate. Instead, start seeds in early July to plant out for a fall harvest. Sprouts taste best when they have experienced a good frost or two.
