How to Stimulate Brussels Sprouts Production: Get More Sprouts

Maximizing the number of Brussels sprouts per stem means better yields and a more rewarding harvest. Over 30 years of growing Brussels sprouts, I’ve learned that a few key cultural practices can significantly boost sprout count and size.

Choose the Right Variety

Start with varieties known for heavy production, such as:

Diablo
Jade Cross
Long Island Improved

These have naturally higher sprout counts and better spacing on the stalk.

Provide Optimal Spacing

Give plants plenty of room—18 to 24 inches between plants—to encourage strong stalk development and allow sprouts to form evenly up the stem. Crowding reduces sprout size and number.

Consistent and Deep Watering

Brussels sprouts need steady moisture to support continuous sprout formation. Water deeply 1–2 times per week, especially during sprout development, to keep the plant energized.

Regular Feeding

Side-dress with nitrogen-rich fertilizers every 4 weeks during growth to encourage leafy stalks that support more sprouts. Avoid overfeeding late in the season to prevent excessive leaf growth.

Pinch and Prune for More Sprouts

Removing the top few inches of the main stem once the sprouts start forming can redirect energy to developing more sprouts lower down. Also, remove yellowing or damaged lower leaves to improve airflow and plant health.

Support Your Plants

Use stakes or cages to keep tall plants upright. Strong, upright stalks can bear more sprouts without bending or breaking.

My Experience Tip

In my garden, pinching the main stem tip increased sprout counts by 20–30% on average. It’s a simple step with big results.

Brussels Sprouts Production Boost Checklist

Choose high-yield varieties: Diablo, Jade Cross, Long Island Improved
Space plants properly: 18–24 inches apart for strong stalks
Water deeply and consistently: 1–2 times per week, especially during sprout formation
Side-dress regularly: Apply nitrogen-rich fertilizer every 4 weeks during active growth
Pinch main stem tip: Remove top 2–3 inches once sprouts start forming to encourage more lower sprouts
Prune lower leaves: Remove yellow or damaged leaves for better airflow and plant health
Support plants: Stake or cage tall plants to prevent bending or breaking
Monitor plant health: Check regularly for pests or diseases and treat promptly
