No use growing them if not producing.

We live in Alabama and super new to gardening. Is it too late to start seedlings now?

I live in South Louisiana and a good time to plant seeds in indoor trays is this month; direct sow in ground would be September. Best of luck in your gardening journey.

My Brussel Sprouts cuttings are sprouting now. Where and how best to transfer them to pkant where they best wiuld thrive, in the garden or in separate trays ? I guess with quarantine mesh in both cases?

My Brussels sprouts plants have a purple tinge on the stems. Are they deficient in some trace element? They also seem to be shedding the bottom leaves which have turned yellow .

Sprouts are more a winter thing than Summer I thought. I don't know about cool climate requirements.
