How your order will arrive
Please see our below guidance on your perennial or alpine's care:

  • Watering: During your perennial or alpine's first growing season, you should provide them with frequent waterings. Try to also avoid wetting the foliage to reduce the risk of disease.
  • Deadheading: To promote a long flowering period, you should deadhead any flowers that appear spent. Simply rescind each flower at their base, taking care to not cut other parts of the plant.
  • Dividing: To really flourish, your perennials can be divided every three to four years. They can be divided when they begin to show less flowers, or appear less healthy in the middle. Make sure to only do so when they aren't currently flowering.

Please note: Herbaceous perennials can die back in winter, so don't be alarmed if this happens and instead look forward to spring!
