The rule: when does your rose flower?

Penn State Extension’s rule is which wood the rose flowers on. Repeat-blooming roses — hybrid teas, floribundas, grandifloras and most shrub roses — flower on new wood and are pruned in late winter or very early spring, before new leaves. Spring-flowering roses that bloom once flower on old wood, and are pruned soon after they finish.

Clemson says it the same way: repeat bloomers need a heavy annual pruning in spring, just as the buds break dormancy; old-fashioned roses and climbers that bloom only once should be pruned immediately after flowering, and not heavily in early spring, because they bloom on wood from the previous year. Dead, diseased or damaged wood on any rose comes out as soon as it is seen.

When and how hard, by kind of rose

⚠️ How hard depends on your winter. Clemson and Missouri write for places where much of the cane survives, so they choose how much to keep. Iowa State says that in the upper Midwest hybrid teas, grandifloras and floribundas often lose a great deal to winter, so the main job is to remove the dead wood and save as much live tissue as possible; only after a mild winter does it cut canes back to 8 to 12 inches. Clemson adds that hard pruning gives fewer, larger blooms, for cutting.

How to make the cuts

1. Start with the dead wood. Iowa State says live wood is green, with plump buds and a white center (pith) when cut; dead wood is brown, with no live buds and a brown or gray pith. Cut at least 1 inch below the dead, brown area, and remove the whole cane if there is no sign of life. Clemson says if the center of a cane is brown, cut farther down into healthy wood.
2. Then the weak and the crossing. Clemson removes all dead, damaged or weak stems, leaving only the most vigorous canes, and where two canes cross, removes one.
3. Open the center. Clemson prunes the bush to be more open in the middle for air circulation, which helps prevent disease. Iowa State says the same: open the plant to air and light.
4. Cut above an outward-facing bud. New growth comes from the bud just below the cut, so Clemson and Iowa State cut about 1/4 inch above a bud facing out from the center, slanted the same way as the bud.
5. Go easy on weak and young plants. Clemson prunes weak-growing varieties lightly and vigorous ones harder, and prunes first-year plants lightly so they put their energy into roots.
6. Keep the tools clean. Clemson dips the shears in a 70 percent alcohol solution now and then so they do not spread disease; Iowa State says clean, sharp tools prevent crushed canes and the spread of pathogens.

Clemson also seals cuts on canes thicker than a pencil with nail polish or wood glue, to keep cane borers out.

Deadheading through the summer

On repeat bloomers, deadheading keeps the flowers coming. Iowa State cuts back to a five-leaflet leaf on established plants, leaving at least two five-leaflet leaves on each shoot, and to the uppermost three-leaflet leaf in a new rose’s first season, so it keeps enough leaves to grow. Clemson cuts just above the next five- or seven-leaf branch, above a strong bud.

Stop in late summer. Iowa State stops deadheading hybrid teas, grandifloras and floribundas in late August or September, and shrub roses by late August or early September, so hips form and the plant prepares for winter. Clemson leaves hips on some roses for winter color and the birds.

Why not in fall

Iowa State says not to prune roses in fall: pruning stimulates new growth that cannot harden off before winter. It also leaves all the canes in place over winter, because after a mild one there is less dead wood to take out. In Minnesota, fall pruning is about safety, not shaping — dead, diseased, damaged and crossing canes, and very tall hybrid teas cut back so the wind does not rock the crown loose. Missouri also trims some of the top of hybrid teas in fall, for the same reason. Clemson, writing for South Carolina, cuts repeat bloomers back by about a third in late fall to stop winter winds breaking canes. For the winter protection itself, see how to winterize roses.

Common mistakes

• Pruning a once-blooming rose in spring. It flowers on last year’s wood (Clemson).
• Pruning before the buds swell. Clemson’s signal is the buds; Iowa State waits until the winter protection is off.
• Leaving dead wood in. Cut at least 1 inch into live wood (Iowa State).
• Cutting above an inward-facing bud. The new cane grows into the center (Clemson).
• Anvil pruners on canes. They crush the stems (Clemson).
• Heavy fall pruning. New growth cannot harden before winter (Iowa State).
