Pagtatanim sa Washington, D.C., DC

Ang apat na petsang mahalaga

Petsa	Kailan	Ano ang ibig sabihin
Huling spring frost (50%)	Mar 24	Kalahati ng mga taon, may freeze pagkatapos ng petsang ito. Average iyan, hindi garantiya.
Huling spring frost (10%)	Apr 6	Isang taon lang sa sampu ang may freeze pagkatapos nito. Gamitin ito sa mga bagay na ayaw mong ulitin.
Unang fall frost (50%)	Nov 18	Kalahati ng mga taon, may freeze bago ang petsang ito. Dito binibilang pabalik ang fall crops.
Unang fall frost (10%)	Nov 5	Taon ng maagang freeze. Kung kailangang matapos ang isang pananim, umani bago nito.

Ang mga petsa ay kinuwenta mula sa sariling huling frost ng lugar na ito, hindi sa generic na zone chart. Ang “best moon days” ay ang mga araw sa loob ng bawat window na pasok sa tradisyonal na phase ng pananim — pareho sa rule na ginagamit ng app.

Pagtatanim sa fall sa Washington, D.C.

Ang fall dates ay binibilang pabalik mula sa unang frost, at may dinadagdag pang oras para sa “fall factor”: umiikli at lumalamig ang araw, kaya mas mabagal lumaki ang pananim kaysa sa pangako ng seed packet. Ang huli na paghahasik ang pinakakaraniwang dahilan ng palpak na fall garden.

Pananim	Ihasik o itanim	Best na moon days	Araw bago mag-ani	Tibay sa lamig

Ang totoo: ang 50% frost date ay pustahan, hindi go signal. Kung masasaktan ka sa nawalang isang tray ng kamatis, sundin na lang ang petsang Apr 6 at maghanda pa rin ng row cover.

Saan galing ang mga numerong ito

Ang frost dates sa page na ito ay observed station normals, hindi tantiya: galing sila sa Washington Reagan Ap (GHCN USW00013743), isa sa 6,808 U.S. station sa NOAA Climate Normals 1991–2020. Ang hardiness zone ay mula sa 2023 USDA Plant Hardiness Zone Map. Ang crop timing ay nakasaad bilang bilang ng araw mula sa frost dates mo, hango sa planting guides ng university Extension.

Gaano ba talaga ito ka-tumpak?

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.

Tungkol sa station mismo: ang weather station ay iisang punto lang. Nagtatago ng init ang mga lungsod, nag-iipon ng malamig na hangin ang mga lambak, at ang hardin sa north slope ay pwedeng dalawang linggo ang atraso sa isang hardin na isang milya ang layo. Ituring mong simula lang ang page na ito at hayaang itama ito ng sarili mong hardin — para diyan mismo ang journal sa app.
