Don't prune too far away from the bud. This can result in the wood between the cut and the bud below dying, often affecting the health of the bud. If the bud fails to grow, die back can cause the whole stem to die.
Don't prune too close to the bud. This often results in damaging the bud itself, jeopardising its ability to grow into a leaf or flower. Pruning too close to the bud can also cause the branch to die back further down the stem.
Don't cut at the wrong angle. This will leave a pointed stub of stem above the bud, which can mean the stem may die back as far as the bud and possibly beyond it.
Do cut just above a bud, but sloping away from it so that any water that hits the cut runs off to prevent rotting. Always use clean and sharp secateurs to prevent the spread of diseases and ensure there is no snagging.
