Pine nuts are the edible seeds of pine trees (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting; in other pines the seeds are also edible, but are too small to be of value as a human food.
Pine nuts have been eaten in Europe and Asia since the Paleolithic period. Pine nuts are regarded as a delicacy in many cultures around the world.
The shelled pine nuts appear like puffed grains of rice. The pine nut is often called the stone pine, because the tree grows well in stony ground.
Regular watering is not necessary. When young need regular watering until the plant is established.
They will grow on almost any soil other than a highly alkaline lime soil. Place the plant in rich well-drained soil and mulch with organic matter. This is a very hardy plant that will tolerate extreme conditions.
Trees benefit from organic mulch.
Will tolerate almost any condition, including salt and are extremely wind tolerant.
Although stone pine is hardy down to -10°C, young specimens are vulnerable to freezing.
Produce cones after 3.5 years.
May be pruned but you have to prune cleanly to healthy branches with good clusters of needles because pines will not re-sprout from bare wood as many deciduous plants will. Never remove any more than 50-60%.
