This was about my 20th year of attempting to grow Brussel Sprouts. Can't say I did'nt try. I think I had one maybe 2 years where I had some real tasty well formed sprouts.
The seed pack always said 120 days. Jade Cross usually and
I tried Bubbles a couple times. Today I tossed 3 plants into the compost pile,they were 210 days old and the round sprouts were just about the size of marbles. I have always had plenty of sun,water,nutrients but not cold weather. My memory is not so good so that I can tie my 2 good years to cold winters. Always grown in sandy soil...you should see the root balls after 200 days...HUGE and DEEP. I really do not pay much attention to my soil ph. everythhing else from
corn to radishes does just fine. I even grow kohlrabi with some nice results. So my question is.....does anybody out there grow B. Sprouts sucessfully on a yearly basis. I am zone 9 actually a coastal 10 Ft Pierce. Right on the water
but no salt problem.
