No drainage on houseplants
Common causes of no drainage and the first things to check, summarized from 2 PlantGrail care records across 1 plant (as of ).
What causes no drainage on houseplants?
Decorative cache pots - plastic, ceramic, or metal containers without drainage holes - trap irrigation water at root level indefinitely. Succulents watered and placed directly into cache pots sit in standing water that prevents soil oxygenation. Within 48-72 hours, anaerobic bacterial populations (Pythium, Phytophthora) explode, attacking root tissue. The outer cache pot conceals the waterlogging, masking early rot symptoms until irreversible crown damage occurs.
Common first steps
- Never plant directly into cache pots - use only as decorative outer shells
- Remove inner nursery pot for watering: Take plant to sink, water thoroughly, allow 30-minute drainage
- Or add drainage: Drill 3-5 holes in cache pot bottom using ceramic/glass drill bit
