Technical Sheet - Pinus Pentaphylla

Common Name: Five-needle Pine / Japanese White Pine

Scientific Name: Pinus Pentaphylla

Characterization: Belongs to the Pinaceae family, and is native to Japan and Formosa.

Evergreen bonsai, with needles grouped in bundles of 5 (pentaphylla). The needles have a gray vein, which is why it is often called Japanese White Pine.

It is a high mountain tree, with slow growth. It is usually grafted onto Pinus Thunbergii, which has a much stronger root system.

Location: Outdoors in full sun, where it receives 3 to 4 hours of direct sunlight daily, protected from strong winds and frosts. It tolerates extreme conditions (very sunny and very cold).

At the peak of summer in very hot areas, the sun exposure should preferably be in the morning or late afternoon, since high temperatures in the pot tend to weaken the plant.

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

For watering tips, please consult the watering technical sheet.

Allow the top layer of soil to dry very well between each watering (to confirm 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 avoid root rot).

There is no advantage to misting the leaves; only do this on days when you fertilize and if the fertilizer is specifically for foliar application, but make sure the leaves dry by nightfall to prevent fungi.

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

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

Pruning: When the candles start to grow, before the needles widen, prune leaving approximately one centimeter, focusing more on the strong areas (which have larger and clustered candles) and less or none on the weak areas.

For pruning tips, please consult the pruning and defoliation technical sheet.

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

Details about transplanting, post-transplant care, and specific fortifiers you can use can be found in the transplanting technical sheet.

Wiring: From late autumn to early spring, avoid wiring in summer.

For wiring instructions, please consult the wiring technical sheet.
