Pinus nigra 'Austriaca' - the Austrian Pine or European Black Pine - is a pine species native to Austria and the Balkans, and one of the most popular pine trees.
This tough evergreen grows well in a wide range of conditions, and is both ideal for screening and windbreaks and tolerant of urban, coastal and exposed environments.
When young it has a conical form, but with age, the growth slows and the form of the tree broadens and usually becomes more irregular. It will reach approximately 25-30m in height.
The stiff needles are arranged in pairs, longer and greener than Scots Pine and with a denser habit. The bark is grey and fissured with silvery plates. When the new growth comes through in the spring it is in the form of bright green ‘candles’. As with all Pines, cones are produced, green initially and brown when fully matured, 2 years later.
It is also sometimes used as a bonsai plant.

Identify my austrian pine
The pines - Pinus - bear needles grouped by 2,3 or 5, and fruits cones releasing scales on the ground.
Plant my austrian pine
Take care not to damage the conifer roots while planting, which is best done in the fall.
Get some potted trees because pines are afraid of root dryness.
Find a place in the sun, in a soil that is not too wet or too calcareous.
Dig a hole twice the size of the rootball, install a support pole at the bottom, and put back half of the soil (starting with the one you left the bottom). Place the root ball not to bury the collar, then put the rest of the earth around the plant. Tamp the soil regularly not to leave pockets of air. Mulch with needles or pine bark. Attach your pine to the support with a flexible link.
In pots, plant in a mixture of sand, potting soil and loam. In this case you need a very large pot ;-)
Water my austrian pine
Water your pine the first year, every week, and provid him at least one watering can twice a week. In pots, wait until the soil is dry to water.
Unprop my austrian pine
Your tree should be well rooted after two years, so remove the stake now that it is not needed anymore.
Prune my austrian pine
This is not necessary, but you can remove the intersecting branches and dead branches, and remove branches at the heart of the tree for a lighter appearance.
Mulch my austrian pine
Leave the needles under the pine. If they do not limit weeding, add some pine bark, or crushed wood.
Check on my austrian pine
The pines fear the attacks of caterpillars, especially the processionaries. These are stinging, beware while cutting the affected branches. Burn the attacked parts.
