How old are oak trees when they get acorns?
600732
Oak trees can start producing acorns when they are 20 years old, but sometimes can go all the way to 50 years for the first production.

sand is small pieces of rock that has been eroded away from a larger stone.it would take years to get a few pounds of sand from a 25 pound rock but wind rain and snow will break down the rock to produce sand. soil is dirt formed from leaves and twigs from trees. all this will decay and produce soil along with rain and other dying vegetation.go into a densely wooded area and you will find soil.be sure its a hardwood forest.that means maples oaks and other varieties of trees but not conifers, conifers are of the pine family and fir all evergreens.the foilage dropped this fall will take about 2 1/2 to 3 years to decay enough to be soil which is the best for growing flowers and bulbs

I like Katie's answer...very thorough...sounds like one of my lectures in my college Botany class...also.....due to chemical changes in the leaves and the slowing of the nutrient flow in the tree/leaves fall off due to the formation of an abscission layer of corky material  at the base of the leaf stem or petiole where it attaches to the tree twig. Cutting off water/food and it drys and weakens the attachment, then with a gust of wind shaking it loose to give us some work to rake them up.....oak trees hold tenaciously to their leaves and are often seen with some of their dry browned leaves on them throughout the winter......

science of dating the ages of trees

An increment borer is the only accurate way to tell a live trees age. It is essentially a hand operated drill that you manually drill through the tree at 4.5 feet from the ground (On hardwoods like oak it can be really hard). An extracter is put into the bit and is removed from the tree with a core sample. Then you just look closely and count the rings, and remove the main bit from the tree.\n\nContrary to popular belief, a trees age cannot be told by how tall or how big around the trunk is. Some species are slow growers and some trees live in repressed situations. I have seen a White Oak that was about 8 in (in circumferance) at DBH (4.5 feet) and only about 40 feet tall that was over 75 years old. A person not knowing would probably guess that tree to be about 20.

Gymnosperms have become less widespread than angiosperms because angiosperms have found ways to take advantage of animals for fertilization and seed dispersal. Angiosperms are not limited by wind and water the way most gymnosperms are. Oaks, for example, can "move" uphill through rodents and birds burying acorns; gymnosperms have more difficulty. And while redwoods are the tallest, bristlecones the oldest, they occupy only a fraction of their former range.

I get deer in my back yard from time to time. They eat the bark off whatever trees I try to plant.\n\n I have a hedgehog and a family of ringneck doves.  A magpie, two voles have a nest under my patio, a wren has a nest under the eave of my front porch.\n\n An owl did live in my back yard but the tree was 300 years old and fell down a few years ago. The owl moved to the woods behind my house. I still hear him hunting at night.\n\nLast spring, I saw a wild boar at dawn but that was only once.\n\nFunny thing is, I live about 20 minutes from the middle of downtown (city of 500,000). Wild, huh?

If you are asking what that means the answer is this;  strong, sturdy, stood the test of time and weathered many a storm..someone who is like and old oak tree is rooted and grounded to a place or belief

Assessing the age of a living tree is straightforward enough -- just extract a core from the tree's circular trunk and count the number of lines in the core formed by the tree's annual growth rings. (The rings of ancient bristlecone pines like Methuselah are more challenging to count, because the trunks are so distorted that new rings may form at right angles to ones formed long before.) But there's much more information to be gleaned from growth rings than simply a tree's age. This information comes to us through the science of dendrochronology.

On top, hickory, walnut, oak.  Trees that do not like wet roots.  On the bottom, box elder, willow, poplar.  They like "wet feet".

Deciduous trees leaves turn yellow because they die in autumn.Evergreen well don't die off,hence stay green.

Any rooted plant does - you could pick an oak tree or a rose bush, or even a marijuana plant if you wanted.\n\nThe roots grow down, toward the center of gravity. The leaves and stem grow up, away from the center of gravity.

By and large, trees don't have absolute lifespans, as animals do. \n\nAccording to The Straight Dope, the most striking illustration of this is the bristlecone pine, Pinus aristata. A 1948 field guide noted that bristlecones reached maturity in 200-250 years, with "extreme ages of 300-375 years." Yet only 10 years later a researcher discovered a stand of bristlecones whose average age exceeded 4,000 years and in one case 4,600 years.\n\nOther examples are less dramatic but still instructive. Red maples live 80-250 years, American chestnuts 100-300, white oaks 300-600, bald cypress 600-1,200. These extremely broad ranges suggest that assigning a "life span" to trees is merely a statistical convenience rather than a reflection of an inherent limit. It would not be surprising (to me, anyway) if much older examples of these species were found.

It is possible to grow orange trees from seed, but if you just got the seed from a fruit that you ate, there is a good chance that your fruit may have been the product of a plant grafted on to a different kind of rootstock.   This means that you could end up getting a different tasting fruit from the seed than the type which you got the seed from.\nEven if you end up getting lucky and having the right kind of fruit produced on your tree it could be 7 years or more before they produce fruit.\nIf the trees are spending time indoors it may be worth getting a dwarfed variety which will stay at a manageable size.

Squirrels are carrying maximum acorns gives you following possibilities:\n\n5,5,5,5,2,2:  or 4 trips by black squirrel, 2 by brown\n5,5,5,3,2,2,2:  or 3 trips by black squirrel, 1 by gray, 3 by brown\n5,5,3,2,3,2,2,2:  or 2 trips by black squirrel, 2 by gray, 4 by brown\n5,3,2,3,2,3,2,2,2:  or 1 trip by black squirrel, 3 by gray, 5 by brown\n3,2,3,2,3,2,3,2,2,2:  or 4 trips by gray squirrel, 6 by brown\n2,2,2,2,2,2,2,2,2,2,2,2:  or 12 trips by brown squirrel\n3,3,2,2,2,2,2,2,2,2,2:  or 2 trips by gray squirrel, 9 by brown\n3,3,3,3,2,2,2,2,2,2:  or 4 trips by gray squirrel, 6 by brown\n3,3,3,3,3,3,2,2,2:  or 6 trips by gray squirrel, 3 by brown\n3,3,3,3,3,3,3,3:  or 8 trips by gray squirrel\n5,3,3,3,3,3,2,2:  or 1 trip by black squirrel, 5 by gray, 2 by brown\n5,5,2,2,2,2,2,2,2:  or 2 trips by black squirrel, 7 by brown\n5,5,3,3,3,3,2:  or 2 trips by black squirrel, 4 by gray, 1 by brown\n5,5,5,3,3,3:  or 3 trips by black squirrel and 3 by gray\n\nThis gives a total of 14 ways if they carry maximum load.  They aren't divided evenly (I hope that's not a requirement).\n\nIf they carry less than maximum load, then it becomes a matter of the different distributions amongst the three squirrels which add up to 24:\n\nbrown = 0, gray = 0, black = 24\nbrown = 0, gray = 1, black = 23\nbrown = 1, gray = 0, black = 23\n...etc...\n\nwhich can be reduced down to the mathematical equation:\n\n1+2+3+4+...+25 = 325 different combinations!\n\n{Now ask why the equation end with "...+25" instead of "...+24"  :-) }

Pansey, rose, dandylion and busy lizzie...they are all planted under the oak tree in my garden.
