How do some trees grow out of nowhere?
In my garden I have a tree that nobody has ever planted. It used to be so small at first i thought it was just a regular 'junk' grass but it kept growing and now a few years later this little grass has grown to be a 20f (6m) tall apricot tree.how is that possible if noone has planted it? arent trees supposed to be planted?
HOW DO I GROW A TITTY TREE?
Some people may think you're kidding, but there actually is such a plant. Its fruit is interesting looking, but poisonous. Here's some information about it: http://www.tradewindsfruit.com/nipple_fr... http://www.kuriositas.com/2010/12/titty-... http://www.amazon.com/Titty-Fruit-Nipple... http://www.turtlegabys-tropical-oasis.com/catalog.php/TurtlegabysTropicalOasis/dt/pd329958 http://www.banana-tree.com/Product/SOLANUM-mammosum-Titty-Fruit-SKU670-787.htm
Why do some trees split into two branches as they grow and others like the big oaks on my yard split branches into three as they grow? What is the name for this?
This is called forking. Genetics plays a large part in it. Much of the forking has been eliminated from crop trees grown for lumber by careful tree breeding. It can also be a result of injury to the tree. Good genetics will still encourage apical dominance by the strongest stem, but sometimes two or more stems will establish this apical dominance after the top being broken out.Some species, like fruit trees, often are genetically predisposed to multiple stems instead of one.
Do the lower branches of a tree die when the tree grows taller?
There is no rule, or pattern, that applies to all trees. Some trees keep their lower branches, others tend not to do that. Some trees can sprout new branches on the lower trunk, some trees (like palms) generally don’t (and can’t) branch at all.That said, there are some generalities that can be made. Trees that grow in forest conditions, especially dense forests (often called “closed canopy”) tend to lose their lower branches as they grow. The lower branches are not likely receiving much sunlight. When that happens the leaves or needles transpire less, using less water and also sending little or no food toward the main stem of the tree. The tree then cuts off the supply of water and the branch dies.Some trees, such as redwoods, tend to become more robust as they grow, with upper branches exceeding the length of lower branches, thus shading out the leaves on the lower branches.Trees that have a southern exposure may keep their lower branches—on that side—for a very long time.
How to grow small papaya trees?
I have been growing papaya trees for years, just transplanted another dozen a few hours ago. When you plant the seeds, the round ones will grow into female papaya trees that will bear rounder fruits, while those a tad less roundish will be males or hermaphrodites. Males have flowers but do not bear fruit; I keep some around to insure that my female trees bear fruit. the hermaphrodites can pollinate themselves and bear fruits that are longer in shape. I interbred wild papayas deliberately with my cultured papaya trees to create trees more resistant to mosaic virus which can infect papaya trees and kill them. There is another papaya disease that causes the root to rot and the tree to fall after the first harvest, which is very very annoying and frustrating to deal will. To keep your papaya trees from growing so tall, which is a problem for sure, cut your trees down with a machete at the height you want it at and it will branch out just below where it is cut 3 to 5 feet is where I would cut them. However, I have had a problem with some trees still growing too high, even if I do that. I recommend you do not plant the seeds of the trees that grow too tall because it is a genetic trait. Save and plant the seeds of the trees you cut and then bear fruit low enough to harvest easily. Plant only the seeds from trees whose papayas are the most delicious and which grow to a height you are satisfied with.
Why do trees growing along the rivers lean toward it?
Two reasons I can think of:Trees growing in competition with others grow towards the light. Consistent illumination comes from an unshaded area - which in this instance is the river. Similar growth occurs on the forest edge where it borders an opening such as a field.Trees growing on the riverbank can be undercut by flowing water eroding the bank, especially on the outside curve of a bend of the river.
Why can some trees grow successfully in a swamp, and others cannot?
It would be best to look at what a swamp is, to find an accurate answer. There are wet-weather ponds in the fields near my home….they are flooded when it rains, and dry out completely afterwards, so they don’t fit a real definition of swamp. The creek behind my field, on the other hand, is always muddy, with numerous springs, feeder streams, root islands, and stretches of water lilies and milfoil moss covering the ever-boggy muck that passes for soil…. a typical southern U.S. swamp.Some trees naturally thrive in swamps, bald cypress, for instance. These have what are called cypress knees which can grow incredibly fast to allow the roots (the knees are segments of roots that bend upwards out of the soil, muck, or water) to allow them to breathe. Cypress are not the only trees that can survive submerged root systems, though. Black gum trees here have large growths around their base that are more like root wood than trunk wood, gnarly and swollen, to allow the tree to survive submersion of the roots. They also grow roots out of the soil or water in coils and twists like some fantasy snake-like creatures writhing in the turbid waters.Other trees that prefer to ‘’rise above’’ the high water line actually create islands as their roots form huge mounds that lay just below or on top of the mucky ground. After a long period of time, as the tree continues to grow, leaves and debris collect around the base of the tree, creating a rich, peaty soil island that in a sense lifts the tree from the water.Trees that haven’t adapted in these or other ways drown when the water level rises, as swamp waters often do. Beavers have a notorious reputation for creating ponds in swampy lands that have stream flow through them, and these ponds are easy to recognize by the expanse of standing dead timber through them. Pines, oaks, hickory, cedars, and other dryland trees simply don’t fare well in situations where their roots are submerged for more than a few days. The exception are those who were gradually flooded and extended roots uphill onto dryer ground.
