How to Plant Your Shrub Roses for High-Altitude Success

Knowing how to best shrub roses for colorado starts with great planting technique. Giving your rose a strong start is the single most important thing you can do for its long-term health. Don’t worry—it’s easy!

  1. Pick the Perfect Spot: Roses are sun lovers. Choose a location that gets at least 6-8 hours of direct sun per day. Good air circulation is also key to preventing disease.
  2. Amend Your Soil: This is the crucial step for Colorado’s heavy clay. Dig a hole that is twice as wide as the pot but only as deep. Mix the soil you removed 50/50 with a high-quality compost or soil amendment. This improves drainage and adds vital nutrients.
  3. Check the Depth: Gently remove the rose from its pot. If it’s a grafted rose (you’ll see a knobby union near the base), plant it with that union 1-2 inches below the soil level. For own-root roses, simply plant them at the same depth they were in the pot.
  4. Backfill and Water Thoroughly: Fill the hole back in with your amended soil, gently tamping it down to remove air pockets. Create a small basin around the plant and water it deeply and slowly until the soil is saturated.
  5. Mulch, Mulch, Mulch: Apply a 2-3 inch layer of wood mulch, bark, or straw around the base of the rose, keeping it a few inches away from the main canes. Mulch is critical in Colorado for conserving water, keeping roots cool, and suppressing weeds.

Feeding for Blooms

  • Remove any dead, damaged, or crossing branches.
  • Trim the whole plant back by about one-third to one-half to encourage new growth and maintain a nice shape.

That’s it! You can’t really mess it up.
