Can you identify this tree and provide treatment and care for maintenance
We viewed your photos. This looks like a redbud tree.
In general redbuds are understory trees and grow best in morning sun and afternoon shade. All you can do is make sure the tree is well watered during dry periods, make sure mulch is no thicker than several inches and away from the base of the trunk, and the tree is not planted too deeply. http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG86%20Common%20Abio...
Also, looks like the tree is planted too close to the house and may have been planted too deeply or too much mulch around the trunk. You should be able to see the flare at the base of the trunk where it joins the root system. Remove the mulch from the base of the trunk. Make sure it is no thicker than several inches and keep away from the base of the trunk. If you see no flare, you can carefully remove the soil from the circumference of the trunk to the point where the trunk flares out into root growth. See the above publication.
Check soil moisture of newly planted trees and shrubs at least once a week all the way up until the ground freezes. Soil that is moist or damp to the touch is fine. If the soil begins to dry out, water the plant thoroughly. Do not overwater; however, you can easily drown newly planted trees and shrubs through too much tender loving care with the hose.
Newly planted trees do not benefit from fertilizer. During the establishment period (up to two years) root growth is more important than top growth. Newly planted trees do not benefit from fertilizer. During the establishment period (up to two years) root growth is more important than top growth.
You do not have to support a newly planted tree. Research has shown that the natural movement of the trunk by the wind actually stimulates root growth and increases trunk caliper more quickly than with staked trees. If the tree is unusually large or is planted in a windy area, staking or guying may be needed for the first year. All supports should be removed after one year.
