Laredo, TX Planting Dates — Moon Phase Garden

The four dates that matter

Date	When	What it means
Last spring frost (50%)	Feb 4	Half of all years see a freeze after this date. It is an average, not a guarantee.
Last spring frost (10%)	Mar 6	Only one year in ten freezes after this. Use it for anything you cannot afford to replant.
First fall frost (50%)	Dec 14	Half of all years freeze before this date. Fall crops are counted back from here.
First fall frost (10%)	Nov 22	An early-freeze year. If a crop must finish, aim to harvest before this.

Spring & summer planting in Laredo

A mild-winter note. Laredo's last frost lands so early that several of these windows fall in late autumn of the previous calendar year — that is not a mistake, it is how a long season works here. Read this table together with the fall one below rather than as two separate seasons.

Dates are calculated from this location's own last-frost date, not from a generic zone chart. “Best moon days” are the days inside each window that fall in the crop's traditional phase — the same rule the app uses.

Fall planting in Laredo

Fall dates count backward from the first frost, and they add time back for the “fall factor” — days are shortening and cooling, so a crop grows slower than the seed packet promises. Sowing late is the single most common way a fall garden fails.

Crop	Sow or set out	Best moon days	Days to harvest	Hardiness
Tomato	Jul 29 – Sep 3	Aug 19	60–85	very tender
Brussels Sprouts	Aug 1 – Aug 18	Aug 13–18	90–110	hardy
Potato	Aug 6 – Sep 7	Aug 27	70–120	semi-hardy
Sweet Corn	Aug 11 – Sep 3	Aug 19	60–100	tender
Pole Beans	Aug 21 – Sep 3	—	60–75	tender

Shallot	Nov 28 – Dec 29	Nov 28–30, Dec 24–26	90–120	hardy

Bottom line: the 50% frost date is a coin flip, not a green light. If you would be sick about losing a flat of tomatoes, plant to the Mar 6 date instead and keep a row cover handy either way.

Where these numbers come from

There is no long-record weather station inside Laredo itself, so these frost dates are modelled, not observed. They come from a half-degree climate grid built by fitting the freeze dates of 6,808 NOAA stations (1991–2020 Normals) against terrain and the USDA 2023 hardiness raster, then reading the cell your city sits in. Checked against the stations themselves, that model lands within about a week on average — and its zone matches the station's exactly 67% of the time and within one half-zone 97% of the time. A cell covers roughly 35 by 28 miles, so this is a neighborhood answer, not a backyard one. If there is a station-backed location near you, prefer it.

How precise is any of this?

Extension recommendations for the same crop routinely disagree by two to four weeks, and occasionally more, so these offsets should be presented as windows and starting points rather than deadlines. Three things drive the spread. (1) Regional risk tolerance: for warm-season crops, Colorado State and Utah State put tomatoes, peppers and melons out about 14 days after the last frost, while University of Missouri's calendar works out to roughly 25-35 days after the last frost and University of Maryland's window runs from the frost date itself out to 45 days past it. That is a real 6-week spread for the single most popular garden crop, and it exists because a short-season mountain state is optimizing against a short season while a humid continental state is optimizing against cold, wet spring soil. (2) Soil temperature versus calendar date: most Extension services now say the honest trigger is soil temperature at 4 inches, not the frost date, and the frost-relative number is a convenience translation. A cold, wet spring can push the real date two or three weeks past the calendar recommendation. (3) Days-to-maturity is variety-specific and is measured differently for direct-seeded versus transplanted crops - seed catalogs count from transplant date for tomatoes, peppers, eggplant and cole crops, but from sowing for roots and greens - so a 'days to maturity' range of 60-85 for tomato is genuinely 60-85 depending on which packet you bought. Additionally, the average last frost is a 50% probability, meaning half of all years have a frost after that date; Extension services commonly advise waiting 1-2 weeks past it for anything frost-tender, or being prepared to cover. Treat every number here as plus or minus about 10-14 days.

On the station itself: a weather station is one point. Cities hold their heat, valleys pool cold air, and a garden on a north slope can run two weeks behind one a mile away. Treat this page as your starting point and let your own garden correct it — that is exactly what the journal in the app is for.
