Gardening 101: How to Prune Roses

July 27, 2020

Mrs. Hart was my next-door neighbor on Long Island. She was what we called “an original owner,” having moved into her brand-new house in a brand-new subdivision in the post-war exuberance of the 1940s. In the ensuing decades, she’d raised a son, outlived a husband, and cultivated magnificent rose bushes. Big, round powder puffs of flowers dotted her front yard in June. She spent most of her time pruning roses, wearing a housedress and a floppy hat to prevent sunstroke.

One time I asked how she kept her roses from going leggy and wild. Mrs. Hart looked up, stopped clipping briefly, and said, “It’s easier to show you than to tell you.”

Need To Know

A rose bush–as opposed to a climbing rose, or a tea rose–is a floribunda. A floribunda, which can be trained as a hedge as well as a bush, is a cross between a hybrid tea and the smaller, more compact polyantha roses often referred to as landscape roses.

A floribunda, which can be trained as a hedge as well as a bush, is a cross between a hybrid tea and the smaller, more compact polyantha roses often referred to as landscape roses. A key distinguishing feature: a floribunda’s flowers grow in clusters rather than as single blossoms at the end of a long stem.

Supplies

  • Pruners
  • Gloves
  • Alcohol
  • Cotton swabs

Disinfect

Clean the blade of your pruners with alcohol on a swab to disinfect them and prevent the spread of disease from one plant to another (roses are especially prone to black spot).

As flowers fade, remove them from the bush to encourage new blooms. Grasp the spent flower’s individual stem and clip it at its base, separating it from the plant.

Shape

Remove deadwood or errant or leggy stems to encourage new, fuller growth. When removing a stem, always make the cut at a juncture where the stem meets a grouping of five leaves.

Angle

Make a clean cut at a 45-degree angle; this will enable rain water to run off rather than collecting in the open wound.
