From mid-October through January.
Pecans that fall are ripe. This is why they fall.
the trees dying
u would have to remove them
Yes, ice cream does fall off trees, but only if somebody puts it there and the wind blows.
Autumn, or Fall. That's pretty much why they call it Fall. the leaves FALL off trees.
In the fall. Trees pull back some moisture from leaves before they dessicate, turn brown, and fall off.
They fall off.
They decompose
Acorns, Bark, other nuts , apples , pears , plums and other fruit.
Once fully ripened, the hust around the pecan will have dried and opened so that the pecan inside is exposed. At this time, wind, rain, or some other external force causes some of the pecans to fall to the ground. Most will remain attached to the husk until the tree is shaken or a long pole is used to dislodge the pecans. Throwing sticks or rocks (not your spouse) up into the tree works as well .
Unlike, other pine trees, their needles actually don't fall off! :)
Gravity, wind, birds, squirrels
