Are you saying that the cypress requires a dormant period to produce adult foliage? The trees are in full sun. I can manipulate some environmental factors, such as providing additional food in the form of Osmocote. They are watered daily & dry out in between.
Cupressus sempervirens (which I have grown before) is unique among the temperate conifers in that it does not require dormancy. After a brief cooling off in the fall, I can grow it under fluorescent lights all winter. Which would provide a quicker transition to adult foliage, growing all winter or a longer dormancy? As a bonsai, the trees look OK as they are, and they are growing, but they appear flimsy. I would like to get some hefty growth on them.
