When to Harvest. Harvest pecans in early September through November when they have fallen from the trees. Start your harvest in 3-8 years depending on the variety and growing conditions. Watch for a substantial portion of the husks to have split and opened and the shell to turn brown before gathering.

Once ready, you can harvest the pecans 1 or 2 ways: Either collect them off the ground as they fall or shake the tree to dislodge them. Inspect the quality of the nuts.

Now when it is harvest time, a pecan tree can produce up to 50 pounds of pecans. The average retail cost for pecans is \$3 per pound. After multiplying 50 X 3, we have $150 which is the profit. To calculate the net profit, we deduct $63 (cost of product) from $150 (total profit) which is a net profit of $87.

For pecan trees to bare nuts you will need two or more different cultivars, as they require cross pollination for maximum productivity. Pecan trees do not bear fruit until they are between the ages of four and 12 years old and that is determined by the cultivar.
