Shore Pine Pinus contorta var. contorta
ABOUT
The plant known as lodgepole pine is characterized by its slender form and a trunk that is often contorted, hence the name. Its bark is thin and scaly, presenting a range of hues from yellowish-brown to darker shades, which can sometimes appear almost black. The needles of this pine come in pairs and can be recognized by their short length and twisted, rigid texture. They exhibit a deep green color, which contributes to the plant's overall evergreen appearance. The cones of the lodgepole pine are compact, with a distinct shape that tapers from a broad base to a sharper point at the tip—a bit like an egg’s silhouette. They remain closed for several years, and in some cases, only open to release their seeds in response to the intense heat of a wildfire. The branches tend to grow outwards from the trunk at right angles, giving the plant its unique and somewhat irregular appearance. These characteristics make the lodgepole pine a distinctive and easily recognizable species within its native habitats.

ToxicityTo humans
Lodgepole Pine is not commonly known to be toxic to humans. However, ingesting parts of any pine tree, including Lodgepole Pine, in large quantities could potentially cause irritation to the digestive tract, resulting in gastrointestinal discomfort or symptoms such as nausea or diarrhea. It is always recommended to use caution and avoid ingesting plant parts unless they are known to be safe and are prepared correctly.
To pets
Lodgepole Pine is generally not considered toxic to pets. Pets that ingest small amounts of pine needles or sap may experience mild gastrointestinal upset, such as vomiting or diarrhea, mainly due to the physical irritation caused by the needles or the oils in the sap. However, large quantities could potentially cause more serious issues, like blockages in the digestive tract, especially in smaller animals. Pet owners should monitor their pets to ensure they are not consuming large amounts of pine material and should consult a veterinarian if they observe any adverse health reactions.

WaterThe Lodgepole Pine, commonly known as the Pinus contorta var. contorta, requires moderate watering. Newly planted trees need water once or twice a week, allowing soil to dry slightly between watering sessions. Established trees are drought-tolerant and typically require watering every two to three weeks during dry periods. When watering, give the tree a deep soak by slowly watering around the base, using approximately 5 gallons for smaller trees and up to 15 gallons for larger, mature trees each time you water.
LightThe Lodgepole Pine thrives in full sun conditions and should be planted in a spot where it can receive at least 6 hours of unfiltered sunlight daily. The ideal spot for this pine is one that mimics its natural environment, with plenty of direct sunlight to encourage strong growth.
TemperatureThe Lodgepole Pine can withstand a wide range of temperatures, from a minimum of -30°F to a maximum of over 100°F. However, it grows best when the temperature is between 40°F and 70°F. It is well-adapted to cold climates and can handle frost without damage.
PruningPrune the Lodgepole Pine to remove dead or damaged branches, improve its shape, or to control its size. The best time for pruning is late winter to early spring, before new growth begins. Remove only the necessary branches and avoid heavy pruning, as pines do not readily form new buds on old wood. Generally, it can be pruned every 3 to 5 years.
CleaningNot needed
SoilLodgepole Pine thrives in a well-draining soil with a mix of sand, peat, and loamy components; it prefers slightly acidic to neutral pH levels around 5.5 to 7.0.
RepottingLodgepole Pines do not require frequent repotting; young trees may be repotted every 2-3 years, while mature trees can be repotted less often.
Humidity & MistingLodgepole Pine tolerates a wide range of humidity levels but prefers drier conditions typical of its natural forest habitats.

Life cycleThe common name for Pinus contorta var. contorta is the shore pine or lodgepole pine. The life cycle begins with seed germination, which requires a period of cold stratification to break dormancy. Once the seedling emerges, it enters a phase of establishment and growth, developing a taproot and beginning to form its characteristic pine needles. The juvenile phase can last several years as the tree grows in height and girth, forming its conical shape. Upon reaching maturity, the shore pine develops cones: male cones producing pollen and female cones developing into seed-bearing structures after pollination. Finally, as an adult tree, it continues to reproduce annually through cone production, with its life span potentially reaching several hundred years if conditions are favorable.
PropogationPropogation time
Spring to Summer
The lodgepole pine, scientifically known as Pinus contorta var. contorta, is typically propagated through the collection and planting of seeds, which is the most popular method. The best time to collect seeds is in late summer or early fall, when the cones are mature but not yet open. To propagate, gather the closed, mature cones and allow them to dry in a warm, well-ventilated area. As the cones dry, they will open to release the seeds. The seeds can then be extracted and sown into a well-drained seeding mix, covered lightly with soil, and kept moist until germination occurs. This process may take some time, as lodgepole pine seeds usually require a period of cold stratification to break dormancy; hence, planning to stratify the seeds in a refrigerator for about 1-3 months before sowing can be beneficial for increasing germination rates. After stratification, the seeds can be sown in the spring, ensuring that frost danger has passed for the best opportunity for successful seedling development.
