How To Train And Grow Climbing Roses

Teach Your Roses to Produce Plenty of Blooms

Climbing roses are actually large rose bushes that produce a single flower at the end of each of their long canes. Unlike true climbers, such as wisteria, climbing roses lack tendrils that can wrap around supports to lend strength to the plant as it grows toward the sun. As a result, climbing roses quickly wind up with long, gangly-looking canes and few blooms. While this growth habit can be perfectly healthy, it's nothing like the photos of thickly-blooming climbing roses you see in magazines.

It's quite possible to train your climbing rose to produce more blooms, but it does take a bit of work. Two training methods work best: you can train your climbing rose against a trellis or self-peg its long canes. Regardless of the training method you use, the result is a climbing rose that produces more beautiful blooms than ever before.

Trellis Training

Training a climbing rose is an important part of creating a cascading, heavily blooming rose specimen. Trellis training, while a bit more expensive than self-pegging, does add a pretty, blooming trellis to your garden landscape. Once you've purchased your trellis at a nursery, garden center, or home improvement store, the process is simple and should take no more than an hour.

What You Need 

  • Sturdy trellis
  • Plastic stretchy plant tape
  • Sharp, clean pruning shears
  • Thorn-proof gloves
  • Climbing rose that grows in your garden zone

Instructions

  1. Attach the rose trellis at least 3 inches away from an outer wall.
  2. Tie the stems of the climbing rose to the trellis with stretchy plastic plant tape as it grows throughout the year. Do not prune until the plant covers the entire trellis.
  3. Gently bend some of the new canes so they grow outward to cover more of the trellis.
  4. Snip off branches that are growing too thick. Every three years, cut out some of the older canes and allow new, younger canes to replace them.
  5. Always remove the weak canes so that the plant can focus strength into a few strong main canes.

  • Always cut faded flowers to encourage more to form.
  • Cut back climbing roses in early spring, while they are still dormant.

Self-Pegging Roses

Climbing rose bushes contain a hormone that inhibits the growth of more than one bloom per cane. This strategy works well for the plant because it ensures that the rose won't expend unnecessary energy on creating more blooms. Unfortunately for gardeners, long canes with just one bloom are fairly unattractive.

Self-pegging is a simple process of arching the long canes of a climbing roses and tying them at the base of the plant. By doing this, you use gravity to inhibit the movement of the hormone, leading to the production of as many as 30 clusters of flowers on the same cane. At the same time, by self-pegging, you prevent your climbing rose from spreading into other areas where you don't want it to climb..

What You Need

  • Pruning shears or clippers
  • Plastic stretchy plant tape
  • Thorn-proof gloves

Instructions 

Like trellis training, self-pegging takes place over the course of years. While your plant will start producing more blooms almost immediately, you'll need to stay vigilant to keep your roses healthy and blooming. Follow these tips for best results:

  1. Start by pruning your roses, removing weak growth and old leaves.
  2. Select the strongest four to six canes.
  3. Gently bend each cane in a loop so the top of the cane meets the base. Use thick gloves to handle the canes, and secure the tips to the base of each cane using the plastic gardeners' tape. The growing tip should be 2 to 3 inches from the base of the cane.
  4. When all the longer canes have been self-pegged, prune mid-sized canes and tuck them into the cage created by the longer self-pegged canes.
  5. Each year, inspect your older canes and replace one or two with new canes to promote healthy plants and vigorous flowering.

  • Self-pegging works only if your climbing roses have supple canes that can bend without breaking.
  • It's best to self-peg during the same time of year that you'd ordinarily prune your roses (which varies depending on your location). 
  • Only self-peg canes that are at least 8 to 10 feet long. If the canes aren't long enough yet, allow them to continue growing until they are.
