Possible allergens include:
(1) pollen
(2) molds
(3) resin or sap from the plant
Recommendations:
(1) Wash the tree or plant and let it dry completely before bringing it inside.
(2) Place an air purifier of adequate size next to the tree or plant.
(3) Get rid of the decoration as soon as possible.
(4) Use an artificial decoration rather than a natural one.
Additional interventions:
(1) If allergy is a known issue, wear gloves when handling the tree.
(2) Clean the room thoroughly while the decoration is up and after the decoration has been removed.
(3) Try to identify a spray that will control mold growth yet not harm the plant or be irritating to the people inside.
(4) The plant should be placed over a barrier sheet that will keep moisture and material from getting into underlying carpet. The barrier sheet can then be taken outside and cleaned once the plant has been removed.
where:
• Washing a tree should be effective in removing pollen and loose plant material in addition to pollen.
• Trying to wash a tree in the middle of winter can be a challenge, especially when it is freezing outside. Some Christmas tree vendors are able to wash the tree after it has been purchased. A covered car wash might be a suitable site if nothing else is available.
• It is important to let the plant dry before bringing it inside, especially if ice has formed. A garage may be the only suitable site if weather is inclement.
• An artificial decoration may be a source of chemicals, allergens or other contaminants.
