Planting & Care

When planting and caring for Rainbow Sensation™ Weigela, it's important to follow a few guidelines to ensure its health and beauty. Here's some planting and care information to help you cultivate this shrub successfully:


  • Choose a location with full sun to partial shade (at least 4-6 hours of direct sunlight per day).
  • Ensure the soil is well-drained, as excessive moisture can lead to root rot. If needed, improve drainage by amending the soil with organic matter.
  • Dig a hole that is slightly wider and equal in depth to the root ball of the plant.
  • Gently remove the shrub from its container, loosening any tangled roots.
  • Place the plant in the hole, ensuring that the top of the root ball is level with or slightly above the soil surface.
  • Backfill the hole with soil, firming it gently around the roots.
  • Water the plant thoroughly after planting to settle the soil and provide moisture to the roots.


  • Keep the soil consistently moist but not waterlogged, especially during the first year of growth.
  • Water deeply and thoroughly, allowing the water to penetrate the root zone.
  • During hot and dry periods, increase watering frequency to prevent drought stress.
  • Mulching and Weed Control:
  • Apply a layer of organic mulch around the base of the plant, leaving a few inches of space around the stem to prevent rot.
  • Mulching helps conserve moisture, suppress weeds, and regulate soil temperature.


  • Prune Rainbow Sensation™ Weigela immediately after flowering, typically in late spring or early summer.
  • Remove any dead, damaged, or diseased branches.
  • Shape the shrub as desired by selectively pruning back branches to maintain its compact form.
  • Avoid excessive pruning, as this can reduce flowering.


  • Apply a balanced slow-release fertilizer in early spring before new growth emerges.
  • Follow the manufacturer's instructions for the recommended dosage and application method.
  • Avoid excessive fertilization, as it can lead to excessive foliage growth at the expense of flowers.

Winter Care:

  • Rainbow Sensation™ Weigela is generally hardy and can tolerate cold temperatures.
  • In colder regions, apply a layer of mulch around the base of the plant in late fall to protect the roots from extreme cold.

By following these planting and care guidelines, you can ensure that your Rainbow Sensation™ Weigela thrives and continues to showcase its vibrant foliage and beautiful blooms throughout the growing season.
