What is wrong with my existing mix and why will new mix solve the problem I am having with fungus gnats?
Fresh mix is the best weapon against these nasty critters because older mix breaks down and becomes attractive to bugs like fungus gnats which can get into the mix from outdoors or even from a new plant you bring into the area. We recommend repotting all plants regularly to avoid creating breeding grounds for insects and also because your beautiful plants will thrive and flourish in fresh mix. In many ways this is just like changing the oil in your car. If done regularly your car performs better and lasts longer. That is true for all of your plants too, and changing the mix also protects your space and your plants from insects and disease. Fungus Gnats feed on fungus and fungus is a byproduct of mix that is old and breaking down. Pouring material into the mix to kill the insects does not improve the quality of a mix that has gone bad.
