- Required
Brussels sprouts are container-suitable. The verified minimum is a 6-gallon pot per plant, about 12 in deep; bigger pots dry out slower and are more forgiving.
- Container plants dry out far faster than the ground โ check daily in summer and water when the top inch is dry. We don't publish a fixed gallons-per-day figure: pot size, material, mix and weather all change it.
- The pot MUST have drainage holes โ standing water rots roots faster than drought hurts them.

Why
A tall, top-heavy cole crop โ use the top of the 4-6 gallon range and a deep, stable pot.
- The 6-gallon minimum gives roots enough volume to support the plant and buffers moisture between waterings.
- A tall, top-heavy cole crop โ use the top of the 4-6 gallon range and a deep, stable pot.
When this doesn't apply
- A too-small pot means constant watering, stunted plants and poor yield โ err larger.
