Growing Brussels Sprouts in Shreveport
Shreveport sits in Zone 8a, with an average last frost of February 15 and first fall frost around December 1 — giving a 289-day frost-free growing season. Cool-season crops like brussels sprout benefit from Shreveport's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
In Shreveport's warm climate, brussels sprout works best as a fall, winter, and early-spring crop. Summer heat bolts most cool-season vegetables before they can produce a harvestable head or root. Plan primary plantings in October through February in Shreveport, not April through June.
Shreveport's sandy soils drain fast — Shreveport gardeners should water brussels sprout more frequently (every 2 to 3 days during peak summer) and add generous compost to improve moisture retention. Raised beds with amended soil perform significantly better than in-ground planting in sandy conditions. Target 1.5 inches of total water per week, split across several irrigation sessions rather than one deep soaking.
