Cryptomeria japonica 'Rein's Dense Jade' / Rein's Dense Jade Japanese cedar
Cryptomeria japonica'Rein's Dense Jade' is a dense, broadly pyramidal dwarf cultivar of Japanese cedar. Its foliage is rich jade-green, turning purple-bronze in sufficiently cold winters. Typical rate of growth in most areas is 9 to 12 inches (22 - 30 cm) a year resulting in a 8 to 10 foot (2.5 - 3 m) conical tree after 10 years in the landscape.
Quite the opposite, John ... 'Rein's Dense Jade' is very easy plant to grow. To answer your question, it would help to know where you live. What size was it when you planted it? Is it getting enough water? ... enough sun?? It's also possible that there are root issues, i.e. girdling roots / planted too deep ...
I live in southeast Massachusetts. It was about five and one half feet when it was planted. It is in full sun. It gets enough water. I use a long moisture prob to test. I was very careful in planting with help from my son who is a retired arborist. The sub soil is hard pan about a 18 inches down. I have planted several other small trees and shrubs without any problem. I have photos of the problem areas.
no need to ever fertilize a tree that's planted in the ground ... 5.5 feet tall is a pretty big plant for transplanting. Something that size could take several years to establish. I also think that MA may be borderline hardiness for this species. Have you seen sub-zero temps since it's been in the ground?
We have not had sub-zero temperatures since planting. I bought it from a reputable nursery and confirmed that it is appropriate for our hardiness zone. I noticed the problem in the spring and it has spread. In the winter, I placed four long fence posts around the tree and used i inch wide plastic ribbon to support the branches.
I took a photo of the area in question to a local arborist employed by a nursery which seems such trees. After examining it closely, he indicated that the area of concern is actually new growth. Thank you for your many replies. I realize that you could not make an accurate assessment by email communication.
