Growing Brussels Sprouts in Sunrise
Sunrise sits in Zone 10b, with an average last frost of Frost-free and first fall frost around Frost-free — giving a 365-day frost-free growing season. Cool-season crops like brussels sprout benefit from Sunrise's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
Sunrise's tropical climate gives brussels sprout year-round potential, but dry season (roughly October through April) is the primary productive window. Wet season rains drive fungal disease fast enough to destroy an unprotected crop within a few weeks. Plan main plantings for dry season and keep beds well-drained.
Sunrise's sandy soils drain fast — Sunrise 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.
