Sitting comfortably at 80 degrees all year round, the Climatron is an ideal place for the 1,400 tropical plants that grow there. In the warm, humid environment, these plants thrive and can easily outgrow the space without intervention from our horticulture team.

For one week each year, the Climatron closes its doors to the public for maintenance. During this time, the horticulture team is pruning the plants high in the dome’s canopy.

This maintenance keeps the plants away from the glass, creates air movement which helps with pest control, and allow light to reach the plants below the canopy.

Usually around 15–20 trees are serviced each year. Often these trees will need to be trimmed again the following year, with many growing 8–10 feet annually.
