The dwarf Siberian (Pinus pumila) is an excellent choice if you live in an area with cold winters. Generally grown for its low, spreading habit, the plant is drought-tolerant, wind-resistant and cold-hardy to minus-90 degrees F. The dwarf Siberian grows to heights of 5 to 10 feet and has an equal spread. The dwarf Siberian makes a low-maintenance yet attractive addition to the garden.
Choose a location for your dwarf Siberian. The tree can do well in either sunlight or dappled shade. The leaves of the dwarf Siberian secrete a substance that will inhibit the germination of other plants' seeds, according to horticulturists at Plants for a Future. This is something to keep that in mind when choosing a location.
Prepare the planting area by digging into the soil, at least 12 inches, with the gardening fork. Loosen the soil and turn it over, crushing any large clumps of dirt. Remove any debris from the area, such as rocks and old roots.
Add a 2-inch layer of compost and a 3-inch layer of coarse sand to the existing soil and mix it in well.
Dig a hole that is the same depth but twice the width of the pot in which the dwarf Siberian is currently growing. Remove the tree from its pot and place it in the planting hole. Backfill with soil and press down around the base of the plant, using your hands or feet.
Water the tree until the water puddles and then hold off on watering again until the top 3 inches of soil is dry. Poke your finger into the soil to determine when it is time to water.
