Willow Grove, Texas, sits in USDA hardiness zone 8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
These conditions suit cabbage, fig, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Willow Grove
Each reading below is measured for Willow Grove itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsWillow Grove runs about 286 days between hard freezes (read from McLennan County, the closest normal to Willow Grove) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredWillow Grove sits in USDA hardiness zone 8b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Willow Grove is in
Willow Grove sits in the Cross Timbers — EPA Level III, inside the wider Great Plains. That is read at Willow Grove's own centroid, and it is not what its county reads: McLennan County is mostly Texas Blackland Prairies. The wider page above you is answering a different question about different ground.

Is it too late to plant in Willow Grove?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 1 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Willow Grove, two things run higher than the national average within ~10 miles of Willow Grove — Underground Storage Tanks (466 sites) and Toxics Release Inventory (40 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Willow Grove
Everything above resolves to Willow Grove as a whole — one PHZM band, read across 3K acres, with hard-freeze dates borrowed from McLennan County’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Willow Grove
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at McLennan County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Willow Grove
When does frost risk typically end in Willow Grove?
The last hard freeze (28°F) in Willow Grove typically lands around Feb 18, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Mar 11.
When is the first frost in Willow Grove?
The first hard freeze (28°F) in Willow Grove typically arrives around Dec 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 17, so the watching starts about Nov 1 — about 286 days after the spring freeze cleared.
How long is the growing season in Willow Grove?
Measured between 28°F hard freezes, Willow Grove sees about 286 frost-free days — roughly Feb 18 through Dec 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 11 to Nov 17, about 251 days.
Is the soil safe to grow vegetables in Willow Grove?
The federal record around Willow Grove is a meaningful one — 608 documented sites, mostly Underground Storage Tanks entries (466), the nearest Underground Storage Tanks record about 0.9 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Willow Grove?
From about Nov 1 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 1 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 1. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
