Pine cones as decor around the house is pretty common. Whether they're sitting in a bowl, decoration for the holidays, or part of a wreath hanging on your door, we think of them mostly as decoration.

You can even buy them online or in stores in various sizes. Obviously, pine trees are their original home and it's easy to collect them off the ground, too.

Whether you hang them on a string or put them in a bowl, besides looking pretty, make sure you place them outside your home or near your garden for these three reasons.

WEATHER PREDICTION

Obviously we have plenty of ways to find out the forecast however pine cones literally respond to changes in humidity and atmospheric conditions according to the  Homemaking website.

When the air is dry, the pine cone scales open, releasing seeds. Conversely, in increased humidity, the scales close firmly to protect the seeds. Observing this natural reaction allows us to predict the weather.

PEST REPELLENT
