Roots & watering
Cocopeat stays too wet
Start below the surface. A damp top alone does not tell you how much air and water the roots have. Look at drainage and irrigation together before changing the medium.

Should coarse and fine cocopeat be layered in a pot?
A layered container is a different physical system from a thoroughly mixed blend. Evaluate the complete profile before adopting a layered recipe.

Why the root zone matters
Water movement can change at boundaries between materials. A coarse bottom layer does not automatically make the fine upper layer drain better.
01 / OBSERVE
Three checks before you change anything
- Identify each layer and its depth in a trial container.
- Compare moisture above and below the interface after normal watering.
- Test a consistently mixed alternative under the same crop conditions.
02 / NARROW IT DOWN
Why are you adding layers?
Choose the closest observation for a suggested next check.
To improve drainage
Check outlets and the overall blend first. Trial the proposed layer arrangement rather than assuming it removes a wet zone.
To save expensive material
Evaluate whether the change affects rooting or moisture uniformity. Cost per filled pot is only one part of the comparison.
To match an existing system
Document the established method and its measured performance before changing layer thickness or ingredients.
03 / TAKE THE NEXT STEP
Leave with something useful
Compare whole-container behaviour in a small trial and keep the layers clearly documented.
Keep in mind
Do not recommend gravel, chips or coarse coir as a universal drainage layer.
