tamarack

Larix laricina

Also Known As - eastern larch
Tamarack (Larix laricina) is a medium-sized deciduous coniferous tree native to Canada and parts of the northern United States. It is easily recognizable in autumn for its evergreen needles, which turn yellow or rusty orange in cooler climates before dropping off for winter. The tree can reach heights of 25 feet (7.6 m) at maturity. Its thick bark and wide crown make it an excellent windbreaker. Its cones and core wood are of commercial value, and tamarack has an extensive root system that is suitable for controlling soil erosion. This hardy species can survive extreme temperatures, and can be found in many regions of northern North America.

watering

When watering your tamarack tree, do so deeply and infrequently. Allow the soil to become slightly dry between waterings. During the summer season, water every 7 to 10 days, or every 3 to 4 weeks during the winter. When you water, try to soak the soil completely so that water is running out of the drainage holes in the pot. Be sure to not leave standing water, as this can cause the roots to rot. Also, do not over-water the tamarack, as this can cause root-rot as well.

sunlight

While the exact amount of sunlight will vary depending on local conditions, a minimum of 4 to 8 hours of direct sunlight per day is usually recommended. Tamaracks are adapted to the extreme weather conditions of boreal forests, so they require direct sunlight for most of the summer and fall months at a minimum. Tamaracks should ideally receive almost full sun throughout the growing season—somewhere between 8-14 hours of direct sunlight throughout April and May, and up to 16 hours of direct sunlight in June and July. In the cooler and shorter days of September, tamaracks can typically tolerate reducing their direct sunlight requirements to 6-10 hours.

pruning

Tamarack (Larix laricina) should be lightly pruned every year in late winter when the plant is dormant. Light pruning includes removing dead and damaged branches with sharp pruning shears, as well as any branches that are crossing or rubbing against each other. Remove no more than 20% of the tamarack’s total foliage and try to keep the shape of the plant intact.
