Container Vegetable Soil Mix, Drainage & Watering in Texas

Texas gardener wants good soil combo for bucket vegetables, moisture/drainage advice, rock‑in‑bottom myth, watering frequency.

Soil Mix (Organic‑Based)

• Compost + Aged Manure + Peat Moss (1:1:1) — or buy 40‑lb bags of quality potting mix.
• Organic matter = drainage + fertility.

Drainage: Holes Are Mandatory

• Drill 4‑6 holes (½") in bucket bottom.
• **Rocks at bottom do NOT improve drainage** — create perched water table.
• A few pebbles to keep soil from washing out is fine.

Container Size

• Minimum 18" wide x 18" deep (≈15 gal) for tomatoes, peppers, broccoli.
• Lettuce, beans: smaller OK (6" spacing).
• Bush varieties save space.

Material

Rot‑resistant wood (cedar) > plastic > clay. Wood insulates roots from temperature swings.

Watering

• Water when top 1‑2" dry.
• Deep soak until drains.
• Texas summer: daily or 2x/day.
• Mulch 2‑3" to cut frequency.
