I planted my brussel sprouts in the fall and they haven't produced any brussel sprouts, only stalk and leaves. They are still in the ground. I used 8-8-8 fertilizer. Do I need to use a different fertilizer?

Gardenate advises plant in SEPT. They need cool or cold weather for best results.

First time growing Brussel Sprouts. Is it o.k. to cut off the larger outer leaves if they are yellowed or otherwise damaged? Will that affect the sprouts in any way?

Did you read this article? It said yes we should absolutely cut off any discolored or damaged leaves, the same goes with EVERY plant in the garden. The reason is because the plant will focus all of its energy on trying to fix its damaged leaves so you should avoid it wasting energy like that and chop them off!!! You want the plant to focus ALL of its energy on growing the actual fruits or whatever it’s supposed to grow.

My Brussels sprout seeds are 175-200 day to maturity. I have tried to start in doors and plant out in June in a mostly shade area, the last 3 seasons, but have never had sprouts develop. I figured it was because we have been having too warm weather, and maybe not enough sun? This season I started in January indoors, and will put them out in March with some frost protection, with more sun. Thoughts?

If you read the article and you’re in zone 9A it says to plant them outside in SEPTEMBER. If you’ve done this the correct time of year (this is a cool weather crop, hence it says plant outside in September) and you’re plants are not producing sprouts all along the stem then maybe you’re not giving it proper fertilizer so it can produce the sprouts??? Also you NEED to make sure that they are NOT planted close together… i’ve done several experiments with these in different growing conditions and the only ones that produced were the sprouts that I planted in a 5 gallon grow bag, using a good soil mixture and proper nutrients placed in a location of my yard that gets full sun. Good luck, don’t give up!!! Also maybe try a different variety.

Brussel sprouts need full sun 6-8 hours a day. Shade area not ideal

The guide here says plants seeds in March and plant out in May. Most veggies need plenty of sun.
