technical sheets - Pinus Thunbergii

Common Name: Japanese Black Pine

Scientific name: Pinus Thumbergii

Characterization: Member of the family of Pináceaes, originates from Japan.

Perennial Bonsai with dark green needles (also called Japanese Black Pine), is a sea orla pine.

It is greatly appreciated for its resistance and rustic shell. There is a variety that emits bark as cork (Pinus Thunbergii Corticosa) and a variety of small needle (Pinus Thunbergii Kotobuki).

Its cultivation is very close to that of other pines used very much in Bonsai as Pinus Sylvestris or Pinus Mugo.

Location: No Outdoor in the full sun, where take 3 to 4 hours of direct sun per day (ideal in the morning or at the end of the day), protected from strong winds and frosts.

Watering: To water abundantly the earth until a lot of water goes out through the drain holes in order to moisten evenly the soil, always above never by immersion, with a fine drain waterer.

Tips on watering, see irrigation technical data sheet.

Let it dry very well the surface layer of the soil between each watering (to confirm if the plant already needs water, touch the earth with the fingers).

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

There is no advantage in spraying the leaves, just do it in days that it adds and if the fertilizer is specific for foliar application, but ensure that they arrive dry at night to avoid fungi.

Nutrition: From February to October/November, with a base plan composed of a complete fertilizer (Green & Gold Bonsai Organic or Biogold), and a biostimulant throughout the year (Bio Bonsai Activ), can still be linked with other products in our range.

Detailed information on how to combine these products the rest of our range, or for a more specific nutrition plan, see complete nutrition plan technical sheet.

Poda: Their vigorous growth leads to the cutting of candles at least 2 times in the year. After the first cut breaks too hard.

We should prun more the stronger candles (greaters) pruning less or nothing the weakest (small) in order to balance the plant.

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

Transplant: With Terra Bonsai Coníferas in February/March, when the candles begin to "move".

Details about transplants, post transplants and specific fortifiers that you can use refer to repotting technical sheet.

Scratch: From the end of autumn to the beginning of spring, we should avoid aramar in summer.
