The best time to repot Junipers is March/April, up to very early May.
Juniperus Rigida (Tosha) can be repotted later, early to end of May, for they tend to wake up slightly later.

Best time for major branch removal / trimming is spring, just as the tree is coming out of dormancy.
Best time for major wiring / bending (trunk and primary branches) is also spring, or in early fall just as temps cool.
Avoid this type of work in June, July, and August, the bark might separate from the cambium layer and your Shinpaku tree could die as a result. Light pruning is fine, but hard bending is a "no-no".
Best time for foliage removal is during the growing season, sparingly to maintain a clean look on finished trees.

Scion grafts on junipers are pretty easy to do. We do these about April/May.

Hornbeam bonsai come in a variety of species. From the Betulaceae family of trees, this deciduous species is gracious with light green foliage and a smooth, muscle-like, grey colored bark. It is reportedly difficult to transplant from a field nursery.
Ironwood is a common name for hornbeam. The name ironwood comes from the ancient times when they used carpinus wood to build ships.
During spring, it produces wind-pollinated pendulous catkins flowers. Hornbeam is monoecious, meaning the male and female flowers are on sperate catkins, but on the same tree.
In general, the hornbeam is a slow growing tree. The leaves will turn yellow, orange and red in the fall and will turn brown when dry. The brown leaves will often stay attached in the winter season.
Six species are popular as bonsai. Two of them are known as Korean hornbeam, while one is known as the European Hornbeam or Common Hornbeam. Two are Japanese Hornbeam and one is the American Hornbeam.
This article is focused on providing additional value, more details on deciduous bonsai care and reminding us of important details as provided in Bjorn Bjorholm's very instructional video.
