Perlite is the perfect medium for helping to increase drainage and aeration in your houseplant soil while keep some moisture retention too as well as promoting healthy root growth.
 
Simply mix it in with your houseplant soil or compost to diversify the particulate size, helping to improve soil draining and root aeration.
 
Perlite is great for adding to your soil to help avoid root rot and disease, as well as imprioving the germination rates of your cuttings and seeds and is suitable for all houseplant types.
 
Perlite is nutrient free, meaning it will not change the Ph of your soil either.
