How to Grow Bosnian Pines
Native to eastern Europe, Bosnian pines are evergreen trees that can grow up to 40 feet tall with proper care and maintenance. Blue-purple cones are the Bosnian pine tree's hallmark, and birds are particularly attracted to its boughs. Bosnian pines need copious amounts of water, fertilizer each spring before new growth starts, and annual pruning. Bosnian pines grow best in full sunlight, but can tolerate partial shade.
Survey the area in which you wish to plant your Bosnian pine. The trees can reach 40 feet in height and 10 feet in width, so consider the potential impact on power lines and ground pathways. Select a spot with well-draining soil and ample sunlight.
Spread peat moss, manure, compost, or a combination of the three, over several feet of your anticipated planting area to prepare the soil. Create a layer between 1 and 3 inches deep. Till the soil, mixing the peat moss, manure, or compost at least 1 foot deep.
Place the root ball into the soil at a depth of 8 to 10 inches. Fill the area surrounding the root ball with the fertilized soil.
Water the sapling until the soil surrounding it is moist to the touch. If the sapling has received less than 1 inch of natural rainfall in one week, soak the ground thoroughly.
Fertilize the tree in late winter or early spring. Bosnian pines need to be fertilized before new growth begins. Prune the tree in late spring, after new growth slows down. Continue fertilizing and pruning for the duration of the tree's life.
