Ussurian pear

Description:

Pear tree bears no fruit, their natural and thriving habitat is Asia. Bark is shedding from white/grey layer (thin) to a Dark red or brown colour, Leaves have black dots/holes and sometimes look deteriorated or weblike showing half of phytochemicals and half of the leaves endoskeleton, Rip/gash/scars (fairly large) on south side of trees trunk, chopped parts of the tree directly at the base of the tree, occasional burrows or gashes within some of the branches, leaves turning from green to red then yellow, lots of spider webs along with a few wasps, some flies, and a Daddy Long Legs Spider. Tree is also growing at an south-east angle (not as severe as the scrawny pear tree beside her). Growth this year varies exponentially from 3 inches on smaller branches and up to 10 inches on the more vital branches.

Habitat:

South facing with high intensity exposure to south-east and south-west sunrise and sunset, lots of room for expansion, exposure to north winds is mediocre, Mulch bedding with lots of room between each pear tree as well as no other surrounding plant specimens in the near vicinity (Closest foreign species is by the pond on the other side of the path). Pear tree is in an urban area, near a walking path and fairly close to a body of water or pond in the Olds College Botanic Gardens #3.

Notes:

To my belief, the pear tree didn't bear fruit this year for two reasons: First is because the natural habitat of the specimen is on the other side of the world in Asia so the plant is readjusting to our canadian climate and suffering from shock. Secondly I would suggest that the open gash on the south side of the trunk was exposed to extensive amounts of sunlight and is focusing her efforts to heal instead of repopulate. The bark shedding and leaves turns is from the changes of season. With the leaves being as deteriorated as they are my off guess considering the sun exposure crack on the south trunk would be that the tree was more susceptible to disease but from my sighting of many insects and the way the leaves were torn I would state that the primary cause of the abnormal leaves was due to insects feeding. Growth had occurred at the base of the tree so pruning was required, combining this aspect and the fact that the tree is located near a walking path, it is my belief this is the cause for the other scars that protrude of the trunk of the tree. The specimen is growing at an angle and my conclusion was that the trees exposure to weather/North winds must be the cause since neighbouring family also shows some extensive evidence of this as well. The difference between growth of each branch must be due to the fact that the plant is facing some habitat/climate and pest concerns so she is doing all she can in order to survive. My suggestion would be to allow her to rejuvenate herself and disregard the use off pesticide until further extreme conditions arise with the insects.
