Harris County Vegetable Planting Dates

Texas AgriLIFE Harris County chart for seed-unless-noted rows, ideal/marginal timing, freeze averages, and heat-shade cautions.

Climate signals

• The source is Vegetable Garden Planting Dates for Harris County from Texas AgriLIFE Extension Service and the Harris County Office.
• The one-page chart uses January through December columns with Ideal Planting Time and Marginal Planting Time labels.
• The chart says Planting times are for seeds unless otherwise noted, with row labels for dormant crowns, transplants, seeds, cut pieces, and slips.
• Average Last Freeze Dates are listed as Hobby 2/8 and Bush 3/1; Average First Freeze Dates are listed as Bush 11/30 and Hobby 12/20.
• Plants grown over winter may require protection during freezing weather, and seeds and transplants started in the heat of summer will benefit from shading during establishment.
