Cryptomeria japonica 'Sekkan' / Sekkan sugi Japanese cedar

Cryptomeria japonica 'Sekkan' is a medium-growing, broadly-pyramidal tree-form of Japanese cedar. Foliage is a striking sulfur yellow, creating a focal point in the landscape. In young specimens, this trait makes them prone to sun scorch, but this becomes less of an issue as the plant matures. Typical rate of growth in most areas is 12 to 15 inches (30 - 35 cm) a year, resulting in a bold 12 foot (3.5 m) tall by 3.5 foot (1.5 m) wide statement in the landscape.

This is an old cultivar that originated in Japan. It is believed that Hillside Nursery of Lehighton, Pennsylvania made the American introduction around 1970. Like many cultivars of Cryptomeria, 'Sekkan' is often seen listed with the redundant term, "sugi" attached to the name (Cryptomeria japonica 'Sekkan-sugi'). This is how it is incorrectly registered in the RHS plant database. Sekkan means yellow in the Japanese language.

I purchased a young Cryptomeria japonica about 5 feet in height, after 5 weeks it was turning brown from the bottom up but underneath the branches the needles still showed green .Thinking it may die I removed it washed away all earth from the roots and replanted it in an area where it was more protected from the sun as now I have read it may have been sun scorched. I mixed some nitrogen fertilizer with a little chicken manure and cow manure and added that to the soil from the dug hole Is there anything else I can do or should not have done
Thank you
