The pecan tree trunk is very tall, thick, and straight. The bark has a light to reddish-brown color, and it usually gets flatter and scalier as it ages. The pecan tree is monoecious. This means it has both the male and female reproductive organs on different flowers. The male flowers are seen dangling from the branches in clusters of 5 to 6 inches.

This is done through proper maintenance, such as fertilizing correctly, sticking to a watering schedule, and managing common diseases. Extensive pruning, if done correctly, can also revive an old tree.
Do you need 2 pecan trees to produce nuts?

Male flowers are located on 4-5 inch long catkins, while female flowers are small, yellowish-green, and grow on spikes at the tips of shoots.

Are pecan trees self pollinating?
Pollination in the pecan orchard is critical to both the yield and quality of nuts. Pecan trees are cross-pollinated (allogamous) and although self-pollination is possible, the result is largely unsuccessful. Pecan trees are wind-pollinated; therefore, pollinators (i.e., bees) are not required to complete pollination.
