My Anthurium substrate mixes: a quick guide
I use two different substrate mixes depending on the size and age of the plant.
Substrate for small Anthurium seedlings
When I repot young seedlings from their germination boxes for the first time, I use a simple mix of:
- Perlite
- Tree fern fibre
- Potting soil
I use these three ingredients in approximately equal amounts. This creates a relatively even and moisture retentive mix for the small root systems while still providing aeration.
Substrate for medium sized and larger Anthuriums
For medium sized plants, which in my growing system means plants around three months or older, I use a chunkier mix containing:
- Tree fern fibre
- Perlite
- Large bark or Orchiata
- Large pumice
- Potting soil
- Sometimes Lechuza Pon, if I have some available
I prefer this mix to be very airy, with plenty of large particles. My plants grow in grow tents, and the pots sit on trays that hold water between waterings. Because the environment stays humid and the substrate does not dry quickly, I generally only need to water about once a week.
In my experience, Anthuriums prefer consistent moisture and do not grow their best when repeatedly allowed to become completely dry. The chunky structure provides airflow around the roots, while the tree fern fibre and potting soil help the mix retain moisture.
Make the substrate work for you
The best substrate is not necessarily this exact recipe. It is the one that fits your environment and the way you realistically water.
If you grow in ambient humidity and enjoy watering frequently, a very chunky and fast drying mix may work well. If you tend to postpone watering, you may need a mix or potting setup that holds moisture for longer.
Consider your humidity, pot type, plant size and watering habits. All these parts work together, and a good setup should make it easier to provide consistent care even during busy weeks.
