    Chinese pistache are great medium size trees, and also consider crape myrtle, and mimosa (silk tree).

    But you have stated two very difficult requirements.

    Most trees and grass don't mix, one or the other or both will suffer in the long term. The frequent watering that is required by grass can cause root rot in trees. Southern magnolia, maples, elms and willows can tolerate more water and may be the best for a lawn area, but may not be root compatible with the sidewalk.

    Planting in close proximity to a sidewalk can invite damage from any tree roots, but the pistache and crape myrtle and mimosa are small enough trees that they shouldn't be a problem unless the tree is planted too close. Stay 10 to 15 feet away from the sidewalk, water deep to encourage deeper rooting. Frequent and shallow lawn grass watering encourages shallow rooting of trees.

    Review the planting information in the link below.

    Verify the watering schedule, water is the most critical for establishing plantings. Until they are rooted in, they require more water than established plants.

    Do the branches bend or snap off and break?
    Try the bark scratch test.

    If you believe the tree has died, contact the garden center you purchased from, as most will replace a tree within the first year.

    Chinese pistache is a deciduous tree, so it is normal for it to go dormant and lose it's leaves as the autumn days shorten and the nights get cold. I don't know your climate there in Canberra, or when dormancy should be expected for Ch pistache, but if you think it's too early, consider premature leaf drop due to extreme water deficit/drought stress, or other physiological stress on the tree.

    The most likely reason for the leaf yellowing is drought stress (water deficit), especially if you are having the heat wave I hear about in Texas this summer. A newly planted tree does not have an extensive root system yet to seek water from a wide area, so it's up to you to water adequately this first season and next while it gets established.

    Water deeply three times a week during hot season and once a week after that, and water the entire area where the hole was dug for the tree planting. The first time you soak it good (today because it's urgent), when you get it muddy wet, use a stick or a shovel poked straight down all around the planting hole to be sure all the soil was settled during the planting and there are no air pockets where roots can dry out.

    Mulch the soil surface to help retain soil moisture.

    Overpruning may not kill a tree directly, but over time, the tree usually suffers from disease, weak structure, etc., and succombs. Never prune more than one-third of the canopy at one time.

    If you suspect root girdling, you may want to repot with fresh soil and fluff out the root mass a little. This will correct a girdling issue.

    Otherwise, it could be multiple nutrient deficiencies if the soil has not been changed in awhile, or fed.

    Here are some articles that will help:

    Thank you so much!
    I'll definitely read the first 2 articles, but as I said this is a mature tree...20 yrs at least. The trees4 dripline is roughly 40' across and the tree 25'+ tall. I have photos now but don't know how to share them without opening a new post. thanks again!
