Place the tarpaulin around the base of the plant. This means the tarp will collect any clippings, and will make it easier to remove waste at the end of the session.
Start by trimming the longest shoots using the hand shears. Make sure you keep the blades parallel tot eh side of the plant. This will give an even finish, overall.
If you’re nervous about spoiling the shape, trim lightly until you can see the existing form clearly. Then you can go back and trim closer to the edge of the structural shape.
Next, continue trimming top to bottom. Work your way around the entire plant.
Any thicker parts of the plant should be cut with the secateurs.
When you’ve finished trimming, run your hands over the entire plant to loosen and trim any stems that may have been tucked away.
