The Comprehensive Guide to Pecan Trees
Pecan trees, revered for their delicious nuts and majestic presence, hold a significant place in both agriculture and nature. This guide delves into various aspects of pecan trees, answering common questions to provide a thorough understanding of these remarkable trees. Most of these questions have longer blog posts associated with them for a more in-depth look at the subject.
What Does a Pecan Tree Look Like?
Pecan trees (Carya illinoinensis) are large, deciduous trees known for their elegant, spreading canopy and sturdy trunk. They can grow up to 70–100 feet tall and have a trunk diameter of 2-4 feet. The leaves are pinnate, with 9–17 leaflets that are lance-shaped and serrated along the edges. In spring, pecan trees produce yellowish-green flowers, and by fall, they bear the characteristic oblong nuts encased in a green husk that turns brown and splits open when ripe. The exposed nut has a moderately hard shell that encloses the nut's editable kernel. The nut will fall to the ground when fully ripe.
How Long Do Pecan Trees Live?
Pecan trees are known for their longevity. With proper care, they can live and produce nuts for over 100 years. Some pecan trees have been known to live for 300 years or more, continuing to provide bountiful harvests for generations.
These pecan trees above were planted in 1900.
Where Do Pecan Trees Grow?
Pecan trees are native to the southern United States and thrive in regions with long, hot summers and mild winters. They are natively found in states like Texas, Oklahoma, and Louisiana. However, they can also be grown in parts of California, Arizona, New Mexico, and Georgia. They thrive in river bottoms with deep soil and adequate moisture. Too much moisture results in scab pressure, while too little moisture causes slow growth.
When Do Pecan Trees Produce?
Pecan trees typically start producing nuts at around 6–10 years of age, depending on the variety and growing conditions. The nuts mature in October to December, with the exact timing varying based on the local climate and tree variety. Harvest can last until March, depending on the size of the crop.
How Fast Do Pecan Trees Grow?
Pecan trees grow at a moderate rate, typically adding 2-3 feet in height per year during their early years. Water, through rainfall or irrigation, and fertilizer are the two biggest determinants for tree growth. Weed control is also often overlooked as a reason for slow tree growth. Growth rates can vary based on soil quality, climate, and care practices.
When Do Pecan Trees Bloom?
Pecan trees bloom in the spring, usually between April and May. The timing of the bloom is crucial, as it determines the success of pollination and subsequent nut production. Pecan trees are wind pollinated and do not rely on insects like bees to pollinate.
Do Pecan Trees Produce fruit every year?
Pecan trees often exhibit a phenomenon known as "alternate bearing," where they produce a heavy crop one year and a lighter crop the next. Environmental factors, tree health, and effective orchard management techniques can all have an impact on this cycle. Hedging, crop load management, and fertilizers all help to keep pecan trees producing consistently.
How Many Pecan Trees Per Acre?
The number of pecan trees per acre can vary depending on the spacing and variety. Typically, pecan orchards are planted with 12–24 trees per acre, with wider spacing allowing for better air circulation and sunlight penetration as the trees mature. Native pecan trees are thinned to 10 to 12 tree per acre. Our newly planted orchids are 30x30 on a diagonal with hedging after about 10 years. Old mature stands of pecan orchards are wider spaced at 60x60. To find trees per acre, take 43,560 square feet in an acre and divide by tree row spacing and space between the trees.
How Often Do Pecan Trees Produce?
Once mature, pecan trees produce nuts annually. However, as mentioned earlier, the yield can fluctuate significantly between years due to the alternate bearing cycle. Without much management, pecan trees will overproduce one year and take several years to recover.
Where can I buy pecan trees?
Pecan trees can be purchased from various sources, including local nurseries, agricultural extension offices, and online retailers. Reputable nurseries specializing in pecan trees often provide a range of varieties suited for different climates and purposes. We like to use Womack Nursery in De Leon, Texas, and Pecan Grove Farms in Bastrop, Texas.
Are Pecan Trees Self-Pollinating?
Pecan trees are not self-pollinating. They require cross-pollination between two different varieties to produce a good crop. It's essential to plant at least two compatible varieties within close proximity to ensure effective pollination.
Where can I buy pecan trees near me?
To find pecan trees for sale near you, consider checking with local nurseries, agricultural extension offices, or online directories that list reputable pecan tree suppliers in your area.
Do Pecan Trees Flower?
Yes, pecan trees produce flowers in the spring. Male flowers are called catkins, which are long, slender clusters that release pollen. Female flowers are small and inconspicuous, developing into nuts after pollination.
How Long Do Pecan Trees Produce?
With proper care, pecan trees can produce nuts for over 150 years. Some trees continue to be productive for up to 300 years, making them a long-term investment for nut production.
Best Pecan Trees to Plant
The best pecan tree variety to plant depends on your location and growing conditions. Popular varieties include ‘Pawnee,’ ‘Desirable,’ ‘Stuart,’ and ‘Cape Fear,’ each offering unique qualities in terms of nut size, flavor, and disease resistance.
Where Pecan Trees Grow Best
Pecan trees grow best in regions with long, hot summers and mild winters. They thrive in deep, well-drained soils with a pH range of 6.0–7.0. Areas with a consistent water supply and good air circulation are ideal for pecan orchards.
Best Pecan Trees
Some of the best pecan tree varieties include ‘Pawnee’ for its early maturity and large nuts, ‘Desirable’ for its excellent nut quality and consistent production, and ‘Stuart’ for its disease resistance and adaptability to different climates.
Do pecan trees need a pollinator?
Yes, pecan trees need a pollinator. Planting at least two different varieties ensures cross-pollination, which is essential for a good nut yield.
How much do pecan trees cost?
The cost of pecan trees varies based on size, variety, and supplier. Young saplings can range from $20 to $50, while more mature trees can cost $100 or more. Bulk purchases for commercial orchards may offer discounts. Because they grow fast when they are young, a large tree isn't required.
How much water do pecan trees need?
Pecan trees require consistent moisture, especially during the growing season. They typically need about 1-2 inches of water per week. Proper irrigation is crucial for healthy growth and nut production.
How long do pecan trees take to grow?
Pecan trees take about 6–10 years to start producing nuts and reach full production capacity around 15-20 years. Their growth rate depends on the variety, soil quality, and care practices.

When do pecan trees bloom in Texas?
In Texas, pecan trees usually bloom between April and May. The timing of the bloom is critical for successful pollination and nut development.
Why do pecan trees not produce every year?
Pecan trees may not produce every year due to the alternate bearing cycle, where they have heavy production one year and light production the next. Other factors, such as poor pollution, pest infestations, and environmental stress, can also impact annual yields.
