Thunbergii Pine Kotobuki Pre Bonsai 10 years old

Common Name: Japanese Black Pine

Scientific Name: Pinus thunbergii

Characterization: Member of the Pinaceae family, it is native to Japan.

An evergreen tree with dark green needles (also called Japanese Black Pine), it is a coastal pine.

It is highly valued for its hardiness and rustic bark. There is a variety that produces bark that appears corked (Pinus Thunb. Corticosa) and a small-needle variety (Pinus Thunb. Kotobuki).

Its cultivation is very similar to other pines widely used in Bonsai such as Scots Pine (Pinus Sylvestris) or Dwarf Mountain Pine (Pinus Mugo).

Location: Outdoors in full sun, where it receives 3 to 4 hours of direct sunlight per day (ideally in the morning or late afternoon), protected from strong winds and frosts.

Watering: Water the soil abundantly until plenty of water flows out of the drainage holes, to evenly moisten the soil, always from above and never by immersion, using a watering can with fine holes.

Tips about watering, consult the watering technical sheet.

Allow the surface layer of soil to dry thoroughly between each watering (to check if the plant needs water, touch the soil with your fingers).

If you have a tray under the Bonsai, never leave any water in it (to prevent the roots from rotting).

There is no advantage in misting the leaves; only do so on days when you fertilize and if the fertilizer is specific for foliar application, but ensure the leaves dry by night to avoid fungi.

Nutrition: From February to October, with a basic plan composed of a complete fertilizer (Green & Gold Bonsai Organic or Biogold), and a biostimulant (Bio Bonsai Activ), which can also be combined with other products from our range.

Detailed information on how to combine these products with others from our range, or for a more specific nutrition plan, consult the complete nutrition plan technical sheet.

Tips on pruning, consult the pruning and defoliation technical sheet.

Repotting: With Conifer Bonsai Soil in February/March, when the candles start to "move".

Details about repotting, post-repotting care, and specific fortifiers you can use are available in the repotting technical sheet.

Wiring: From late autumn to early spring; wiring should be avoided in summer.

Instructions on wiring can be found in the wiring technical sheet.
