Quick answer
Drainage problems can come from compacted soil, fine-textured native material, low grade, perched water, roof runoff or an undersized drainage system. The right soil blend helps only when it addresses the actual cause.

Identify where the water comes from
Look for roof downspouts, slope, neighboring runoff and irrigation before changing the soil.
Check whether the site has an outlet
A fast-draining planting mix cannot make water disappear if the entire area sits in a low basin with nowhere for water to move.
Improve root-zone structure where appropriate
In containers and engineered beds, coarser mineral components such as pumice or perlite can increase air space and drainage.
Avoid random layering
Putting coarse rock below fine soil does not automatically create a well-drained planting profile. Engineered systems should be designed intentionally.
Match the plant to the site
Sometimes the best solution is changing the planting strategy rather than endlessly modifying the soil.
- For containers, drainage can usually be adjusted more predictably than in native ground.
- For severe site drainage issues, consult the appropriate landscape/drainage professional.
- Custom blends can be built around drainage requirements for professional projects.
