When to Prune Your Plants for Next Season

This is a very common question I get asked. When should I prune my native grasses? When should we prune our rose bushes? Do I need to do this every year? These are all great questions, and don’t worry—at one point, I had no clue either.

We are based in Broomfield, Colorado, and this plays a major role in determining the best time of year to prune your plants. In Colorado, winters are very cold and snowy, typically from November to March or April. Because of these conditions, you want to wait until late February or early March to cut back plants like native grasses, Russian sage, or rose bushes. Pruning during this time ensures the plants remain protected during the harshest winter months while giving them a clean slate before new growth starts.

Here are some quick pruning tips:

  • Native Grasses & Russian Sage: Cut them down to about 3–4 inches high. For some grass species, consider a less aggressive trim if needed.
  • Rose Bushes: Use hand pruners to carefully remove any dead or damaged wood from the previous season. Make your cuts just above outward-facing buds and always prune on a frost-free day.

You might wonder: “What happens if I don’t prune these plants annually?” Neglecting this maintenance can result in stunted growth, fewer blooms, and an untidy appearance. Over time, this can also affect the plant’s overall health. Pruning allows for better air circulation, encourages vigorous growth, and keeps your plants looking their best.

So, the moral of the story? Every late February or early March, grab your hedge trimmers and hand pruners, and get your plants and shrubs ready for a new year of growth. And hey, maybe you’ll feel inspired to cut some “dead weight” out of your own life, too. After all, new growth is always a good thing!
