Build a Backyard Garden Pond: Step-by-Step

A well-designed pond is surprisingly easy to install and maintain. Site on level ground with ≥5 hrs sun, accessible to a hose, and visible from house/deck/patio. Bigger is better: <2 ft deep and <8 ft diameter collects heat and algae. In cold climates, dig ≥3 ft deep for winter survival. Call utilities before digging. Outline shape with a garden hose; dust with sand/flour for digging guide.

Materials

• PVC liner
• Sand
• Fine gravel
• Brick edging
• Flagstone coping
• Round stones for bottom

Construction

1. Dig hole min. 24″ deep, slope sides slightly. Remove large roots/sharp stones.

2. Level rim. Use level on 2×4 across top. Pack bottom/sides with 2–3″ moist sand to protect liner.
3. Position liner. Leave 12″ excess all around. Edge with brick; trim liner so coping hides it.

4. Gravel bed for coping. Lay coping extending 1–2″ beyond brick. Let water stand 2 days to dissipate chemicals. Position potted water plants on stacked bricks for proper height.
5. Set plants at required depths. E.g., water lilies: pot rim 6–12″ below surface. Add round stones on bottom. Consult supplier for fish/snail/tadpole stocking rates per cubic foot.
