Are Christmas Trees a Source of Indoor Mold?

A study on a live Christmas tree showed that they could be a source of allergenic mold. Measurements showed that mold counts were 800 spores per cubic meter of air during the first three days, which are just about normal levels. However, mold counts began rising from the fourth day on, and by day 14, when the tree was taken down, the measure was 5,000 spores per cubic meter of air.

Mold allergies affects about 15 percent of the population. Allergic reactions can include nasal, eye, and throat irritation, nasal stuffiness, and headache. There is also a link between mold and asthma attacks, and a risk of invasive fungal disease for those people with compromised immune systems.

Most Christmas trees are cut in advance of the holidays and stored in a moist environment, making them a likely mold source. However, artificial trees and ornaments collect dust in storage and are therefore another possible source of allergy irritation.

Dr. Mercola''s Comments Dr. Mercola's Comments:

Mold grows in moist environments, so the relationship between live Christmas trees and mold is perhaps not a big surprise. Most trees are cut far in advance and stored in a moist environment to keep them fresh, and then you place it in water for a couple of weeks while in your home. This container of stagnant water and the moist tree trunk can contribute to the increase in mold spores.

If you start displaying physical symptoms such as sneezing, runny nose, red eyes or skin rashes after putting up your Christmas tree, it may very well be a sign that you’re having an allergic reaction to mold from your tree. Exposure to molds can increase asthma attacks and sinus problems in both children and adults.

Unfortunately, mold spores are very difficult to destroy, even with chemical agents such as bleach (which is itself toxic), so your best way to reduce the problem is through preventive measures.

Using a plastic tree instead of a real one would be one good solution, in addition to being less expensive in the long run. Just make sure you store it in a box or covered container during the rest of the year, and shake out any collected dust before you begin decorating it for Christmas.

Strengthening your immune system is also important, as all allergies are a sign of an impaired immune system. Gary Null has an excellent video on this topic called Supercharge Your Immune System, which is a must-see.

Following my eating plan, adhering to foods that complement your nutritional type is one of your most potent ways to keep your immune system working optimally.

In my clinical experience, I have also found that both krill oil and fish/cod liver  oil can help reduce allergic responses by enhancing your immune system and soothing irritated mucous membranes. (If you take cod liver oil, remember to get your vitamin D levels tested. Because although most Americans' vitamin D levels are far less than optimal, it is still possible to overdose on vitamin D.)

You may also want to consider using a high-quality air purifier. This is a simple way to reduce your exposure to potential allergens, regardless of the season.

How to Avoid Other Christmas Tree Hazards

But there are other, more common Christmas tree hazards to also keep in mind this season. Follow these important tips to keep your family and home safe:

  1. Avoid using artificial snow sprays, which can cause lung irritation if inhaled

  2. Always turn off your tree lights when you go to bed or leave the house 

  3. Never burn Christmas tree branches in your fireplace. It can cause the buildup of creosote, which is a highly flammable compound

  4. Make sure your tree is placed as far away as possible from heat sources, such as a fireplace or portable heater

  5. Hang all ornaments that are breakable, have small, detachable parts, or that look like food or candy on higher branches where small children can't reach them

FeeBird - Mould is a very big health issue for some people and these people could be made very sick by a mouldy tree.

For most people that would be true. For my daughter she was seriously ill every time we had a real tree........lethargic and very congested. With artificial, she is fine.

The fact that the mold count didn't begin increasing until the third day after the tree was brought into the house indicates to me that the problem is not actually the tree, itself.

I would be willing to bet that if the experiment was repeated using a large vase of flowers, you'd get similar results - not because the flowers or the tree bring mold, but because the relatively warm standing water in the vase or Christmas tree stand fosters mold growth.

Correct!  Water activity, in combination with a warm circulating environment, indoors, allows for air borne yeast, microbes and mold spores to incubate in 72 hours, on the plant material, and hence create the air quality problem.

What about a live POTTED tree?  No water to cause mold and you can take it out and plant it after the holiday. Or do you all think this refers to the kind in soil also?

I believe that Mold affects more like 99 percent of the population. Doug Kaufmnan has a health show on TV in which he talks about Mold and Fungus causing disease. Using what I learn from Dr. Mercola and Doug I have improved my health beyond what I ever thought possible.

Dr. Mercola's article is so true! When my son was about 3 years old we started buying live trees. Every time he would be sick at Christmas, and I mean really sick. It took me a couple of years to figure it out. The third year when I realized it was the tree, the tree was thrown in the back yard 2 days before Christmas. Never again. We have been putting up the artificial tree ever since then with every one having a great, sick free holiday. Happy Holidays everyone!!

I have a big fig (decorative fig/ficus not the type that produces the edible fruit) tree in a big pot that I've been pruning and training into a Christmas tree shape for about the last 5 years.  I bring it inside two weeks before Christmas and decorate it up.  

Everyone who see's it comments on how beautiful it is and what a good idea it is.  It loses a few leaves during it's two weeks indoors but figs are incredibly hardy and it's back to normal a few weeks after being returned to it's outdoor spot for the next 11.5 months.

Fig trees are cheap, especially if you buy them small.  A small, sparse tree will turn into a thick luscious tree in no time if it's in a big enough pot and given plenty of fertiliser.  You can prune them into whatever shape takes your fancy.  The key is to start shaping them young and continuing to maintain the shape if you want it to look thick and luscious.

I have a friend who's now done a similar thing with a Box hedge in a pot and it looks amazing pruned into a cone shape and decorated.

A living tree produces negative ions, absorbs radiation.  There is no mould to worry about and figs and box hedge (as far as I know) are low allergy and produce no pollen.  You can also enjoy them all year round!

What a brilliant idea! No mould, no additional expense, no phthalates, no carbon footprint and no living things harmed in this approach!

No needles to clean up afterward either!
