The Quick Answer to “How Much Light Does Cabbage Need?”

How Much Light Do Cabbages Need - a large cabbage growing in a well-mulched garden in full sunlight.

Cabbages require full sun exposure for optimal growth and development. They need a minimum of 6 hours of direct sunlight per day – but ideally, they should receive 8 to 10 hours of sunlight daily. Inadequate sunlight can result in stunted growth, small heads, and poor-quality cabbage.

If you are growing cabbages indoors or in an area with limited sunlight, you may need to supplement light by hanging grow lights or some sort of LED plant lights to ensure they receive enough light.

FAQs About How Much Light Cabbage Needs

Can cabbages grow in shade or partial shade?

Cabbages can tolerate some shade, but they require at least 6 hours of direct sunlight to grow and mature properly. If they don’t receive enough sunlight, they may produce small or misshapen heads, and the leaves may become pale and limp.

Do cabbages need consistent sunlight?

Cabbages prefer consistent sunlight, but they can tolerate some fluctuations in light levels. However, sudden changes in light intensity or duration can cause stress and affect their growth and development.

Can cabbages grow in winter or low-light conditions?

Cabbages can grow in cooler temperatures and lower light conditions, but they may grow more slowly and produce smaller heads than those grown in full sun. If you’re growing cabbages in the winter or in an area with limited sunlight, consider using grow lights or another artificial lighting to supplement the natural light.

What is the ideal temperature range for cabbage growth?

Cabbage grows best in cool weather and can tolerate temperatures of approximately 45°F to 75°F (roughly 7°C to 24°C). If the temperature gets too hot, the cabbage heads may bolt or split, and the leaves may become tough and bitter.

What are the signs of too much or too little light for cabbages?

Too much light can cause the leaves to turn yellow or brown, while too little light can cause the leaves to develop splotches called “leaf scorch”. Both too much and too little light drastically reduces the quality of your cabbage heads.
