Why Is My Container Not Draining?
Fix drainage problems and prevent root rot in your container plants
Drainage Problem Checklist
Check holes: Are drainage holes clear and unblocked?
Test soil: Does water bead up on surface (hydrophobic)?
Check saucer: Is pot sitting in standing water?
Soil age: Has potting mix compacted over time?
Common Drainage Problems & Solutions
Blocked Drainage Holes
Roots or compacted soil can block holes over time. Fix: Clear holes with a chopstick or pencil. Place mesh or broken pottery pieces over holes before adding soil to prevent future blockage.
Compacted Potting Mix
Old potting soil becomes dense and drains poorly. Fix: Repot with fresh mix containing perlite or pumice. For long-term pots, top-dress with fresh mix annually and repot every 2-3 years.
Hydrophobic Soil
Peat-based mixes repel water when too dry. Water beads up and runs down the sides. Fix: Soak entire pot in water for 30 minutes, or add a drop of dish soap to watering can to break surface tension.
Frequently Asked Questions
Why isn't water draining from my pot?
Common causes include: blocked drainage holes, compacted soil, soil that's become hydrophobic (water-repellent), or the pot sitting in a saucer of standing water. Check drainage holes for roots or debris, and ensure the potting mix hasn't become too dense over time.
Can I use a pot without drainage holes?
It's not recommended. Pots without drainage require very careful watering and often lead to root rot. If you must use one, add 1-2 inches of gravel at the bottom and water sparingly. Better: drill drainage holes or use it as a cachepot with a draining pot inside.
Should I put rocks in the bottom of my pots?
Contrary to popular belief, gravel at the bottom doesn't improve drainage - it actually creates a perched water table that keeps soil wetter. Instead, use well-draining potting mix throughout. Only use gravel if your pot has no drainage holes.
How do I fix waterlogged potting soil?
Remove the plant, let the root ball dry slightly, and repot with fresh well-draining mix. Add perlite (20-30%) to improve drainage. If soil is hydrophobic, soak the entire pot in water for 30 minutes, or use a wetting agent. Avoid letting pots sit in water.
