Pollination Info for Canadian Hemlock (Tsuga canadensis)

Canadian Hemlock is a coniferous tree that belongs to the family Pinaceae. It is dioecious, which means that it has separate male and female reproductive structures. Hemlock trees produce small, yellowish-green, male and female flowers that are inconspicuous and typically appear in the spring.

The male flowers, or pollen cones, are produced in clusters at the tips of the branches. They are small, rounded structures that contain numerous tiny pollen grains. The female flowers, or seed cones, are also small and inconspicuous. They are green when young and turn brown as they mature. Each seed cone contains two seeds, which are enclosed in woody scales and are not released until the cone dries out.

Canadian Hemlock is wind-pollinated, which means that it relies on the wind to carry pollen from the male flowers to the female flowers. This method of pollination is common in trees that produce inconspicuous flowers. Because the female flowers are located on separate trees from the male flowers, the wind plays an important role in transferring pollen from one tree to another.

Overall, Canadian Hemlock is a hardy tree that is well-adapted to its environment. Its inconspicuous flowers and reliance on wind pollination allow it to produce seeds without expending too much energy on reproductive structures. This allows the tree to invest more resources in growth and survival, which is important for its long-term health and well-being.

• Choose a planting location that is shaded or partially shaded, with well-drained soil that is acidic or neutral pH.
• The Canadian Hemlock prefers moist, cool soil, so ensure it gets enough water during the planting process to establish roots.
• Dig a hole twice the width of the root ball and just as deep as the height of the root ball.
• Remove the tree from its container or packaging and gently tease out the roots before placing it in the hole.
• Fill in the hole with soil and gently tamp it down around the base of the tree.
• Water the tree deeply after planting.

Care

• Water the tree deeply once per week during dry spells, ensuring the soil stays moist.
• Mulch around the base of the tree to help retain moisture and keep weeds at bay.
