Just a few limbs
First on the list, the most common occurrence that I see daily.
You buy a beautiful little Tree at the nursery, its tag is short and sweet but boldly stands out is its beautiful flower or it's easy maintenance qualities. You don't know much about trees and don't have a chance of saying its Latin name. You take it home and plant this little safe Tree just metres from your home.
It grows …… and then this is where I come into play. Your small safe Tree is now a 30-foot-tall dangerous Tree that spreads it limbs nearly over your entire roof. With every storm you hear branches hit the roof and hope they haven’t become too big to come crashing thru. The Tree’s root system seems to attack the mower and stretch for kms under the earth, sucking water, nutrients and life from every other living plant in its reach. It’s low maintenance quality that the tag boldly said has now become a Climber's delight. This is what keeps me in work - wrong placement of trees. Take a breath and research your greenery. Ask a tree expert or even use old faithful google if need be. Make sure your Tree suits the size of your land and that it won’t become a danger to any of structures, water pipes or land.
Your Tree can stand most of nature's elements but sometimes with interference from man or planted in unknown land where it is not native to, it can soon become a danger with broken limbs or up-rooting and falling during Mother Natures worst. When pools are put in, or pipes are tunnelled thru underneath the tree roots, a lot of times major roots are cut and damaged. This Tree that had put roots deep down to hold it tall, has now become unstable and can fall with any sort of gust of wind. As well this, it can allow the tree to be wide open to diseases and fungal infections to enter into the damaged root. This can result in the death of the Tree.
Exactly the same with pruning. If a Tree is incorrectly cut and pruned, the new branches it grows aren’t as strong as the first. The branches are weak and unable to cope with the elements. Incorrect cutting or pruning can also allow abnormal regrowth which becomes another danger to the tree or surrounding plant life. This can allow diseases to penetrate its cuts, it can then spread the disease to other living plant life. Example: Mistletoe. It is airborne and attaches to a host Tree in its branches. Where there are cuts or damaged limbs, the Mistletoe then sucks all nutrients and water from the host, causing the host to become weak. The host tree could then die or become more vulnerable to further diseases.
