Evergreen tree whose leaves are needles. The needles are grouped in pairs. They belong to the order of the conifers because its fruit, the pine, has the shape of a cone. It’s a tree which you can find on the coast and it has vigorous growth.
Place outside and exposed to the sun. It’s one of the trees with most need of sunlight.
Pines need controlled watering. An excess of watering and with spoil with poor drainage can have fatal consequences for the life of the mycorrhizae. These are fungus whose roots act in a symbiosis with those of the pine and help it absorb mineral elements of the ground like phosphorus. Without this fungus the tree weakens and at then dies.
Spring and autumn. It’s preferable to use organic fertilizers which favour and preserve the mycorrhizae.
Every 3 years, at the moment of budding and before the opening of the needles within the buds. In our Mediterranean zone this is in the middle of March.
100% Kiryuzuna, or mixed with a 50-70% of Akadama.
Pruning and pinching
To be done in the coldest months of the year. Leave needles and leaf buds on the branches otherwise they will dry.
As needles appear, pinch back overgrown shoots. In the growing season, remove long main shoots, trim one-third to half of this year’s new candles.. In late summer or early autumn, remove old needles and crowded twigs to let in light.
From October to March. It’s recommended to use copper wire because pines are very flexible trees and the wire has to remain for a long time on the tree.
In Japan this pine is considered to be masculine. Its vigour, the texture of its bark, the dark colour of its needles and their rigidity give it this character.
