    This link might help: http://www.hort.uconn.edu/plants/detail.php?pid=456

    I might suggest that when moving trees, one needs to dig 10'' rootball for each 1'' diameter of the trunk. A tree with a 3'' trunk should have a rootball dug at least 30'' wide...or greater.

    In my research I found a few links for you that may be of some help.
    One of the links strongly suggests that a professional needs to make the diagnosis of Needle Cast disease.

    In my research I found many reports of the Umbrella Pine taking on a yellow cast to the needles during winter with the tree shedding these needles and returning to it's normal green color during the growing season.

    A soil test is a good idea to check the soil, as this tree prefers a slightly acidic soil.

    It is possible that a yellowing tree could indicate a more serious issue and I've listed this link to give you more information and what to look for.

    This slow growing conifer does need a planting site with protection from wind.

    Unfortunately a fence will not likely be enough protection.
    You may want to find a more protected planting location for this tree.

    They will survive much lower than this... The problem comes with the heat. They can only survive to our zone 8a and below. This will mean that it will prefer cooler temperatures than what your zone has to offer. This does not mean that it will not survive there, but it will mean that it will need special protection from the heat, and full sun. It may not live near as long either.

    I would highly recommend something for a warmer climate, but I will include a link to their care while the idea is mulled over: https://www.gardeningknowhow.com/ornamental/trees/umbrella-pine/umbrella-pine-planting.htm

    Topping a tree usually has disappointing, bordering on disastrous results. The crown becomes ragged without a central leader. You are then forced to keep pruning to maintain a pyramidal shape. These trees are sometimes grown as bonsai so pruning is possible. Instead of looking to change the tree, first consider whether your site conditions meet its needs. Japanese umbrella tree requires acidic, rich soil, prefers full sun (6 hours daily) with protection from hot afternoon sun and consistently moist soil. The last condition is tricky because the tree does not let wet or clayey soil. It also needs protection from winter winds which strip moisture from the "needles" and might kill an emerging branch. If you aren't meeting its needs, it will not perform well. In zone 5, you are on the edge of its hardiness range. It may be set back if your winters have been more harsh than typical. Images on the internet show some highly sculpted trees but I found no information on pruning to encourage more branches. I did read that insufficient sunlight may result in a leggy, open appearance. good luck

    Never top a tree, you can remove bottom branches if needed.
    Review the care needed in the article below.

    It may just need better water management and patience for recovery period from the planting. Back off on the daily watering now and depending on climate factors, water no more than three times a week unless its really hot and dry. If you have been watering shallowly, just the surface, then you may need to deep water but less frequently. If on the other hand it's too muddy wet all the way down in the planting hole, then it could be suffering from anaerobic conditions and needs to dry out a little between waterings.

    So much depends on the planting technique expertise and set back that can occur from poor handling, drying out and root loss during planting. Soil quality in the backfill is important.

    It's still alive after a month and just a little wilted, so that's a good sign, not perfect but not yet a crisis. It should be putting out new roots and taking up water now and you should see it respond and perk up and start to put out some new growth soon.
