Minimizing Die-Back When Cutting Back Geranium (pelargonium) Stems

geranium die-back is unsightlyCutting back geranium (pelargonium) stems is not so straightforward as it sounds. Firstly, not every node will produce side shoots unless an axillary bud is visible. But geranium stems are often devoid of axillary buds, and any dormant buds are invisible. So we cannot just cut back to any node and expect new shoots to appear where we want them. Quite often, unsightly die-back (pink) left protruding into nowhere is the result of our efforts, try as we might.

This is why I recommend waiting till a strong new shoot is growing before cutting back to it see 'Cutting Back Geranium Stems'.

And even then I leave a good margin of error (red). This can be carefully cut away once our new branches are growing (lime - best if they're growing stronger than this). New cuttings can be taken from the off-cuts.

WHAT IF NO SHOOTS ARE AVAILABLE?
If a stem needs to be shortened and there are not side shoots, cut back about half way and hope for the best. After a few weeks, new shoots might have developed lower down the stem; if not, let them die back, then remove. We can't win them all . . ..
