Drill drainage holes in the container if necessary, and then add a 4cm layer of horticultural grit, to aid drainage.
Fill the pot two-thirds full with compost and mix thoroughly with the horticultural grit.
Place the plants in the pot, adding the taller ones towards the back. Firm them well and add more compost around them to fill in any gaps. Water the container and allow to drain.
Add the cut pieces of bamboo, pushing them down into the compost. Angle them to deflect any rain. Cover the compost with a mulch of more horticultural grit, and move to its final position.
