|Winter frost damage can show up quickly as can root stress. Typically if the roots are stressed over the winter months it won't show up on the shrub or tree until spring when the tops try to put out new foliage. It is at that time they discover the roots were damaged. You might try pruning off the browh foliage if it is only at the tips of the branches. If it is further in towards the center, just leave it alone on try to determine what might be wrong with the roots. Overly saturated soils can cause root rot; frozen but dry soils can dehydrate the roots. Dig around and snap a few of the small roots in half. Healthy roots will be creamy white inside; dead or diseased roots will be brown or rusty colored. Soggy soil and roots and a foul odor are indications of overly saturated soils. Hope you can determine just what happened to your juniper!
