Brussels Sprouts Hercules: Harvest Until the First Frosts

Brussels Sprouts (Brassica oleracea var. gemmifera) Hercules variety is a high-yielding, late-maturing plant. It forms a sturdy stalk up to 1 meter high, bearing 20-30 dense sprouts. The main advantage of Hercules is its frost resistance: the sprouts actually taste sweeter after the first light frost as sugars accumulate in the tissue.

Soil: Where Does Hercules Gain Its Strength?

This cabbage requires significant nutrients throughout the season. It prefers dense yet fertile soils.

• Best Choice: Fertile Loamy soils (Type 1) with a neutral pH.
• Soil Check: Perform the sausage test. If the soil rolls into a flexible stick (Type 1), it’s perfect: the ground will hold the heavy plant firmly and ensure stable root moisture.

Best Companions (Good)

• Sage and Thyme: Their strong scent deters cabbage moths.
• Onions: Help fight off aphids.
• Spinach: Can be harvested in the rows while the cabbage is still gaining height.

Main Enemies (Bad)

• Walnut Trees: Walnut juglone stunts sprout development, making them loose and bitter.
• Strawberries: Compete for nutrients in the upper soil layer.
• Shade: If Hercules doesn't get at least 6 hours of direct sun, the stalk will be thin and the harvest poor.
