Pecan is a long-term planting — a young tree typically takes about five years to bear its first real nuts, and then produces for years. It's hardy across USDA zones 5 through 9. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Pecan is
Pecan grows as a perennial and reaches around 120 feet at maturity. It blooms yellow in early spring.
How to grow Pecan
Pecan grows in USDA zones 5 through 9 and takes about five years to begin bearing. Pecan does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 7.5, on well-drained ground. It needs around 3,500 growing degree days to mature, a growing season of at least 140 frost-free days, and about 400 hours of winter chill to set fruit, which is why climate matters as much as soil.

Plant it right
Set pecan in full sun with well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.
Match the soil
Pecan prefers pH 5 to 7.5 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Be patient, then harvest
Pecan takes about five years to its first meaningful harvest (USDA-NRCS). Prune annually while it establishes, and the tree will then crop for years.
Good to know
Good news for pet owners — pecan isn't known to be toxic to dogs or cats. (Source: ASPCA.)
Pecan isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.
Where Pecan thrives
Pecan is hardy across USDA zones 5 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Pecan in my zone?
Pecan grows in USDA hardiness zones 5 through 9 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long until Pecan bears fruit?
Pecan typically takes about five years after planting to bear its first real crop, then produces for years (USDA-NRCS). Soil, climate, and rootstock all shift the timeline.
When should you plant Pecan?
Set pecan out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.
How much sun does Pecan need?
Pecan needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Pecan need?
Pecan prefers soil pH 5 to 7.5, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Pecan attract pollinators?
Pecan isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Pecan safe for pets?
Pecan is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
