Propagating in perlite
Perlite is a lightweight, inert medium that’s great for delicate roots. It doesn’t hold much water in itself, but it allows good airflow. Perlite usually works best in a semi-enclosed setup (like a bag, small greenhouse or dome) to help retain humidity.
What you’ll need
Tips for success
We recommend wearing a dust mask when handling dry perlite, as it can be quite dusty. To avoid breathing in the particles you can also rinse the perlite to remove the finest dust before use.
Fill your pot with perlite.
Moisten the perlite with water until it’s damp but not soggy.
Optionally place it in a humidity dome. Make sure it has some ventilation, to prevent stagnant air and rot.
Check regularly to keep the perlite moist.
Maintain a stable temperature while roots form.
Frequently asked questions
Why is perlite a good medium for plant propagation?
Perlite is a lightweight, inert medium that is excellent for delicate roots because it provides good airflow. It works well in a semi-enclosed setup to help retain humidity.
What should I do before using dry perlite for propagation?
When handling dry perlite, it is recommended to wear a dust mask due to dust. You can also rinse the perlite to remove the finest dust particles before use, preventing you from breathing them in.
Is a humidity dome necessary when propagating with perlite?
A humidity dome is optional but can help retain humidity, as perlite itself does not hold much water. If you use one, ensure it has ventilation to prevent stagnant air and rot.
How do I keep perlite moist for plant propagation?
After initially moistening the perlite until it's damp but not soggy, you should check it regularly to ensure it stays moist as roots form.
