Container Gardening Supply Checklist: Pots, Soil, Tools & What You Really Need

Starting a container garden? The supply list is short, but choosing right saves money and frustration. Here's exactly what you need—pots, soil, tools, and optional upgrades—organized by priority.

Essential: Containers

What Works (Almost Anything That Drains)

• Nursery pots (free from landscapers/garden centers)
• 5-gal buckets (drill holes, food-grade preferred)
• Fabric grow bags (best root health, see separate guide)
• Stock tanks, troughs, half-barrels
• Repurposed: tubs, crates, drawers, coolers (drill holes)
• DIY wood boxes (cedar best; line others with landscape fabric)

Minimum Depth by Crop

Drainage: Non-Negotiable

• Drill ½" holes every 4–6" (bottom + lower sides).
• Elevate on pot feet, bricks, or 2×4s.
• Gravel layer at bottom? Myth. Creates perched water table. Use soil to bottom.

Essential: Growing Medium (Not "Dirt")

Buy or Make Container Mix

Bagged (easiest): Look for "container mix," "potting soil," or "raised bed mix." Avoid "garden soil," "topsoil," "compost" (alone).

DIY Recipe (5-gal batch):

• 5 gal compost (sifted, diverse sources)
• 1 gal coarse sand or perlite
• 1 gal peat moss or coconut coir
• 1 cup balanced organic fertilizer (4-4-4 or similar)
• Optional: 1 cup worm castings, ½ cup azomite/rock dust

Key Properties

• Drains in 10–30 seconds (test: water pot, time drainage).
• Holds moisture but not soggy.
• Lightweight, doesn't compact.
• pH 6.0–6.8 for most vegetables.

Essential: Watering Tools

• Watering can (2-gal, long spout, rose head) — for small gardens.
• Hose + wand (shut-off valve, gentle shower) — for 10+ pots.
• Drip irrigation kit (timer, tubing, emitters) — best for consistency, vacation-proof.
• Moisture meter (probe) — eliminates guesswork. $10–15.

Essential: Hand Tools

• Hand trowel (sturdy, wide blade)
• Cultivator/claw (aerate surface, mix amendments)
• Pruners (bypass, sharp)
• Gloves (nitrile-coated for wet work, leather for thorns)

Highly Recommended

• Slow-release organic fertilizer (4-4-4 or 5-5-5) at planting.
• Liquid fertilizer (fish emulsion, kelp, compost tea) for weekly feeding.
• Mulch: Straw, shredded leaves, wood chips — conserves moisture, cools roots.
• Plant supports: Tomato cages, stakes, trellises, peony rings — install at planting.
• Labels & marker: Waterproof. Track varieties, dates.

Optional Upgrades

• Soil thermometer (germination temps)
• pH meter/strips
• Row cover / frost cloth (season extension)
• Garden cart/wagon (move heavy pots)
• Potting bench (back-saving)
• Grow lights (indoor seed starting)

What You DON'T Need

• Gravel/pot shards at bottom (harmful myth).
• Special "container" fertilizers (regular organic works).
• Expensive decorative pots (function > form).
• Peat pellets, Jiffy pots (direct-sow or reusable cells better).
• Chemical pesticides (IPM + organic sprays suffice).

Start with: 3–5 appropriate containers, quality mix, watering can, trowel, fertilizer, mulch. Add tools as your garden grows. The best supply is the one you actually use.
