Rose Fertilizing

When & How to Fertilize Roses

Quick Tips:
  • If you want to give your rose bushes an extra boost, fertilizing is the way to go.
  • There are a few types of rose fertilizer which either come in liquid and granular form.
  • Use a fertilizer suited for roses from your local garden centre. Be sure to follow the manufacturer’s guidelines for quantity and frequency.
  • Make sure the soil is moist before you fertilize to avoid burning the roots.
  • When it comes to fertilizing roses, newly planted bushes need fertilizer that’s high in phosphorus, which promotes root growth.
  • Established roses won’t need to be fertilized until early spring as they begin to leaf out.
  • After the first blooming cycle has finished, you can fertilize for the second time to encourage repeat-flowering.
  • Stop fertilizing your roses in late summer when they begin preparing for winter dormancy.
