19.1 Advanced Drainage Techniques
Dual-Layer Drainage: Place 1″ of coarse gravel or LECA clay balls at the bottom, then add a landscape fabric layer before filling with potting mix. This prevents soil washout while ensuring proper drainage.
Internal Wick System: Thread a cotton rope through a small hole near the bucket’s base. The rope draws excess moisture into a lower reservoir (another waterproof bucket), reducing root rot risk.
Self-Watering Wick Pots: Insert a 2″ wide felt strip vertically from a lower water reservoir into the soil. Refill the reservoir every 5–7 days for consistent moisture without daily watering.
