Stop snapping dead flowers off your roses

When a rose bloom fades, most people pinch it off where the flower meets the stem. It is quick and it tidies the bush. It is also the reason so many roses end up with a thicket of thin, dead-ended twigs by August. The video shows the alternative: follow the stem down, cut above a bud that faces outward, and let the plant branch from there.

What a snapped stub does

A rose stem with its flower gone has no growing tip. The short stub left above the top leaf has no bud on it either, so the plant has no reason to send anything up it. It dries back, turns brown, and often takes the next centimetre of healthy stem with it as the dieback creeps down. Meanwhile the bud that could have made the next flower sits lower, still dormant, waiting for a signal.

What a proper cut does

Every leaf on a rose has a bud tucked in its axil, the angle between leaf and stem. Cut just above one of those buds and you remove the tissue above it that was keeping it dormant, the same apical dominance mechanism that runs every woody plant. The bud breaks within a week or two, and because the cut is right above it the new shoot grows straight from healthy wood.

Two details make the difference:

The base and the tips

While the shears are out, take the thin crossing shoots off right at their base. They will never carry a bloom worth having. And on strong young shoots, pinch the soft tips with your fingers to make them branch lower, where the flowers will be at eye level rather than above your head.

Hard or snap

The closing question divides gardeners because snapping is genuinely faster, and on a big hedge of roses speed counts. But on the few bushes you look at every day, the extra ten seconds per stem is paid back in the next flush. Every cut you make now becomes two new stems later.
