Frequently Asked Questions
What hardiness zone is Redstone Arsenal, Alabama?
Redstone Arsenal sits in USDA hardiness zones 8a-9a, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
When does frost risk typically end in Redstone Arsenal?
The last hard freeze (28°F) in Redstone Arsenal typically lands around Feb 2, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
What vegetables grow in Redstone Arsenal?
Redstone Arsenal's zones 8a-9a support a wide range — strong performers include Pecan, Muscadine Grape, Okra, Collard Greens, and Fig. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Redstone Arsenal, really?
Officially, Redstone Arsenal sits in USDA zones 8a-9a (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Redstone Arsenal?
The federal record around Redstone Arsenal runs heavier than most — 1,060 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do I protect my plants from frost in Redstone Arsenal?
As the season closes around Alabama's first fall frost near Oct 25 - Nov 20 (NOAA 30-year climate normals (1991–2020)), a few moves buy time: cover tender plants with floating row cover or an old sheet on still, clear nights, water the soil the afternoon before a freeze so it holds warmth overnight, and harvest frost-tender crops like tomatoes, peppers, and basil before the first hard night. Hardy greens and root crops shrug off light frost and often sweeten after it, so leave them in.
