Texas planting calendar

When to put transplants or seed in the ground across Texas, worked out from the average last spring and first fall frost for each USDA zone in the state, and what to line up before you commit ground. Written for farms that sell what they grow.

What it costs to grow an acre in Texas

No published Texas budget is transcribed here yet, so this page shows planting dates only — we do not publish cost figures we cannot source. Neighboring state budgets from NC State, UGA and UF/IFAS are on the crop profitability page.

Every figure is transcribed from a published land-grant enterprise budget for that state. These are planning budgets built from grower panels and dealer quotes, not surveys of what farms actually spent — your invoices override them everywhere they exist.

Before you commit ground

A planting date tells you when a crop can grow — not whether it pays. Work out your breakeven price, then line up who is buying before you plant.
