Pollination Info for Emerald Green Arborvitae (Thuja occidentalis 'Smaragd')

Emerald Green Arborvitae (Thuja occidentalis 'Smaragd') is a cultivar of the eastern white cedar, native to North America. As an ornamental plant, it is considered to be very low maintenance and easy to grow.

Thuja occidentalis 'Smaragd' is a dioecious plant, meaning that it has separate male and female flowers on different trees. The male flowers produce pollen while the female flowers have ovules that can be fertilized by the pollen. Thus, for pollination to occur, there must be at least one male tree nearby to provide pollen to the female flowers.

The timing of pollination for Emerald Green Arborvitae is typically in early spring, with the male flowers producing pollen as early as March. The female flowers are receptive to pollen for a short period of time, generally in mid to late spring.

To ensure successful pollination, it is recommended to plant at least one male tree for every five to seven female trees. The male trees should be planted in close proximity to the female trees, ideally within 50 feet, to ensure that the pollen can travel to the female flowers. Male trees can be identified by their small, brown, cone-like structures that form during pollination season.

Overall, pollination is an important process for the production of seed cones and the continued growth and survival of Emerald Green Arborvitae. Proper placement and management of male and female trees can ensure successful pollination and a healthy population of these beautiful trees.
