Austrian black pine is a ubiquitous large evergreen tree native to southeastern Europe. Pyramidal when young, it eventually forms a high-crowned, broad-headed tree. The needles are long and stiff; the bark is dark brown and platy. Tolerant of urban and seaside conditions, it prefers sun and well-drained soil. It is susceptible to twig blight. Use Austrian black pine as a windbreak, screen, or specimen plant.

| Germination | 1. Place the seeds in a container with tepid water and soak them for 24 hours. Change the water and wait another 24 hours. 2. Put the seeds in a small plastic bag and cover with damp sand. Place the bag holding the seeds in the refrigerator for one to two months to stratify the seeds, which is preserving seeds in layers of moisture-laden peat, soil or sand. Check the sand and water as needed to maintain moisture. Don't allow the seeds to get soaked. 3. Fill small pots with compost. Place one or two pine seeds on top of the compost in each pot, then cover the seeds with a thin layer of sand. 4. Water the sand and compost to add moisture, then place the pots in a warm, sunny location. As the seedlings emerge and grow, the soil needs to remain moist, not wet. 5. Repot the pine trees into medium-sized pots in the fall. Grow them in the pots for the following season until they are large and strong enough for transplanting into the landscape. |
