Botanical Name: Pinus Parviflora
Pinus Parviflora, also known as Japanese white Pine (as white lines are visible across the centre of the needle), is an evergreen conifer specimen part of the five needles Pines. Japanese white Pines are extremely popular with Bonsai enthusiasts, thanks to their beautifully elegant movements and colours. As their light grey bark is quite smooth while still immature, they are usually grafted onto Black Pines to highlight a more fissured bark.
Apart the broom they are suitable to all styles.
Location and Position
Pinus Parviflora enjoy a full sun exposition. It will require good ventilation during the winter period if it is protected from the frost to avoid fungus and insects. Shelter is advised if the weather is rainy.
Avoid waterlog and bone-dry soil, since this specimen prefers moist soil.
My preference is to feed with liquid fertiliser from spring to summer every two weeks. In autumn I use slow release organic pellets once.
Pruning and Pinching
In spring candles begin to sprout, and by early summer pinching the strong one on strong area first (usually apex) and strong from medium areas after (middle part of the tree) is part of the tree maintenance to distribute energy. Structural pruning can be done in late summer to autumn along with needle plucking or trimming of old needles to allow air and light.
Repotting and Soil
Early spring or late summer seem to be the best time to repot. A very well drained soil mix is required, and since Pines are Mycorrhizal dependant, it is a good idea to add it into the soil mix to provide the beneficial Fungi that this specimen relies on.
My inclination is to wire during fall to avoid the risk of scars.
