Make a freestanding trellis for a large pot
Build a timber trellis sized to a large pot. Match the stakes to the pot, brace the crosspieces and tie in a lightweight climbing plant.

Before you start
Pick a broad pot and a light climbing plant that suits a small support. Sketch how far the stakes go into the pot and how high the frame will stand above it. A tall frame has more leverage in the wind, so start low and use a sheltered spot.
Tools and materials
- Timber stakes, crosspieces and diagonal brace
- Tape measure and square
- Saw, drill, clamps and eye protection
- Exterior screws
- Soft plant ties
Step-by-step instructions
Set the stake spacing and depth
Measure inside the rim at the points where the stakes will stand. Check the available depth and mark an insertion line on both stakes. If you are planting a new pot, position the stakes before the root ball goes in.
Lay out the frame
Lay the stakes parallel on a flat bench at the measured spacing. Cut equal crosspieces to span them. Use a square to mark each joint and leave the lower parts of both stakes free for the potting mix.
Fasten and brace
Clamp and drill pilot holes before adding exterior screws. Fit a diagonal brace across the back of the frame to stop it shifting sideways. Check for projecting screws or splinters before moving it.
Set and train
Insert the stakes deeply without forcing them through roots. Guide the plant with loose ties and check the frame stays upright.
Check the result
Lightly nudge the top of the trellis and check that the stakes, frame and pot return to an upright position without rocking. Make sure the first ties are loose enough for stems to thicken. Check the stability again as foliage fills the frame.
Troubleshooting
If the pot rocks or the frame catches the wind, reduce the height or move it to a sheltered spot.
