Perlite is the ideal material to prevent growing mediums becoming compacted and waterlogged by maintaining good drainage, soil aeration, and aiding in moisture retention. It is widely used when taking cuttings and transplanting seedlings to grow on. Use in replacement of grit, especially as it is a fraction of the weight.
It is a white, lightweight granular material that is made from expanded volcanic glass. Its expanded nature means that it is very porous, so it is excellent for absorbing water, and it improves drainage by trapping air in the soil. Perlite is very dusty, however, so dampen it with water before using in a well-ventilated area.
If you want to improve drainage, mix with compost at a ratio of 1:4 and do this before planting to make sure you have an even mix.
If you want to take cuttings, use a specific cutting compost and mix at a 50:50 ratio. Fill your pots and water thoroughly and let drain for several hours before inserting your cuttings.
If you want to sow seeds, mix into compost at a 50:50 ratio. You can also use a fine layer to cover seeds that need light to germinate as the perlite will let the light through whilst keeping the soil moist.
