This sycamore was cut down when it grew too big, so we turned its stump into a planter with evergreen grasses and variegated ivy.
Drill out the centres.
Use a variety of drill bits.
Chisel between the holes you have made.
Drill a couple of holes in the side of each stump for drainage – enough deep holes will remain where you can’t reach, these will form a ‘sump’ to reduce risk of drying out on hot summer days.
I used a breadknife on the root ball so the grass would fit into the cavity.
The stump is in a shady damp location – we picked evergreen plants to cheer up the corner of the garden.
The final result.
