Drainage in Pots

Without water drainage, even the most expensive substrate turns into a swamp with yellow leaves.

1 min read

Draining is not just about "putting stones for aesthetics". It means that excess water should exit within minutes and air should return to the substrate's pores.

Components

Sufficient holes, a layer of expanded clay if there is a saucer, a mix with perlite, and emptying the saucer. A single micro-hole blocked by a root leads to slow flooding.

Signs of Failure

Smells like rotten eggs, mosquitoes, soft leaves, moss on the surface. Watering less is not enough if there is no drainage: drill holes or change pots.

What We Recommend at Control Garden

Pots with good volume and packs of expanded clay/perlite. Drainage is a one-time purchase that prevents a summer of funerals.

FAQs

River gravel at the bottom?
It can create a capillary blockage. Better to use lightweight expanded clay and real holes.
Geotextile at the bottom?
A cut prevents substrate from escaping. Do not completely cover the holes.
Hydrogel and drainage?
They can coexist if the gel is mixed, not blocking the outlet.
