My Brussels sprouts also are shorter than in other years, I think it is from the deeper cold we were having this year that they are not growing as tall or as vigorous as usual. They also seem to be taking longer than normal to form the sprouts.

Woops!! I forgot to answer to your question.... I wouldn't mess with the top leaves, just leave it be and they might get taller as the season moves along and set more sprouts as they grow, but normally once the little cabbage head forms at the top they stop growing taller. With this weird weather I just don't know what to expect anymore from anything. My plants are grown from my seeds and not store bought plants and they seem to be doing the same as you describe yours are doing.

Same here,I grew mine from seed & most of the plants are very stubby.I have sprouts forming on most plants,but they are very loose in form & not tight like a sprout should be.I think we are right at the border for growing sprouts here & the constant up/down temperatures affects them.They prefer a constant cool season,rather than 75 one day & 40 the next.I think I will plant them earlier next time & hope that the sprouts have started to form as the first hard freeze hits.

I need your help? My brussel sprouts have not grown the plant is tall but i havent taste any brussel sprouts because they are to small what can i do so they can get bigger? And they have alot of grey little bugs what can i do to get rid of them.
