Did you know that indoor plants have been proven to improve the quality of air in our homes & offices? They also have a positive effect on our mood, productivity and behaviour. But just like humans they can be greatly affected by slight changes in the environment. Changes in light levels and temperature (air conditioning) can cause leaves on a plant to suddenly drop.
The simple solution is don’t move your plants too often or if they aren’t doing well look at where they are located in terms of light levels and temperature.
