Q.growing brussel sprouts
I purchased one pot of brussel sprouts, in one month they we’re so thick I transplanted half of them, now I have two starter plants. They’re getting thick also. Should I split them up again?
You can continue splitting the plant and plant the off shoots. This can however cause the production of the sprouts to be delayed in the mother plant if the plant is disturbed or stressed.
