Copilot question: “What are the recommended growing zones for Brussel Sprouts. Please give examples of which US states are in the growing zones. And can you grow them indoors?”

Brussels sprouts thrive in USDA Hardiness Zones 3-10. These zones cover a wide range of climates, making Brussels sprouts a versatile crop for many regions in the United States.
Here are some examples of states within these zones:

• Zone 3-4: Northern parts of Minnesota, North Dakota, and Montana.
• Zone 5-6: Parts of Illinois, Ohio, and Pennsylvania.
• Zone 7-8: Virginia, North Carolina, and parts of Texas.
• Zone 9-10: Southern California and parts of Florida.

Brussels sprouts are cool-season crops and are best planted for a fall or early winter harvest. They require a long growing season and can tolerate light frosts, which actually improve their flavor.

As for growing Brussels sprouts indoors, it is possible but can be challenging due to their size and long growing season. They need plenty of light (at least 6 hours of direct sunlight or equivalent artificial light) and space to grow. If you decide to try growing them indoors, ensure you have a large enough container and a strong light source to mimic outdoor conditions.
