Use stones or piles of cobbles to trap the liner to finish vertically:
To edge an informal pond:
- Before adding sharp rocks to the shelf area lay an off cut of liner on the shelf to protect it from damage.
- Add the rocks or cobbles to trap the liner upright between them and the ground around the pond.
- Hold the folds in place and the vertical upstand in position by piling the stones up against the rim.
- Blend the hard landscaping from the shelf level up and over the rim edge.
- The vertical liner should be covered and not seen.
- Fill with water halfway up the vertical liner upstand.
- Use rainwater if possible as this does not contain chlorine from tap water.
- If you use tapwater please use Chlorine Guard.
- Leave pockets or gaps between the rocks to add baskets of suitable plants later.
- Plants will grow between or over the hard landscaping and soften the look.
Edge an informal pond by adding stone to the top shelf edge
- When all the stone work is in place there should be no slack in the liner.
- All folds should be weighted into position.
- Fill the top shelf with water to its planned level.
- Wait a few days to check your pond holds water and is not leaking.
- Trim off the surplus liner.
- The finished pond with all edges complete has no liner visible.

- The stone forms the link between the water and the rest of the garden both visually and for the wildlife visitors.
- You can also use logs and place plant baskets behind a curving wood branch (see Right-hand side of image)
- Next add shelf pond plants in baskets onto shelf areas and waterlilies, Aponogeton distachyos and oxygenating plants to deep area of water.
