Miami Gardens gardening questions
Does it ever frost in Miami Gardens, FL?
Rarely. From 1991 to 2020, NOAA's N Miami Beach #2, FL station, 1.7 mi from the city center, did not reach 32°F at all — too seldom for NOAA to compute frost dates. Zone 11a means the coldest night of an average winter is 40 to 45°F (4.4 to 7.2°C), so frost is essentially unknown, though cool nights can slow tropical plants.
When should I plant tomatoes in Miami Gardens, FL?
Without a frost season, plant by temperature: set out tomatoes Jan 15 – Mar 31 and Aug 1 – Sep 15. Fruit set drops when nights stay above about 75°F, so avoid timing harvests for the hottest weeks. More: tomato planting by zone.
When is the best time for lettuce and broccoli in Miami Gardens?
Cool-season crops do best in the mild months: plant lettuce Sep 15 – Feb 15 and broccoli Sep 1 – Jan 15. Summer heat makes lettuce bolt and broccoli flower early.
Did Miami Gardens's hardiness zone change on the 2023 map?
Yes. Most of Miami Gardens was zone 10b on the 2012 map and is zone 11a on the 2023 map — half a zone warmer, like about 56% of U.S. ZIP codes. The shift comes from a newer 1991–2020 averaging period plus more weather stations and better mapping; it does not mean last frost comes earlier. Why the 2023 map is warmer.
How does Miami Gardens compare with Miramar, FL?
Both are in zone 11a. Frost is rare in both Miami Gardens and Miramar, FL (6 miles away), so both garden year-round.
