Australia’s Most Effective Fertilizers for Roses


Feeding your plants is important to keep them healthy and strong. Roses require extra care to ensure big, beautiful blooms, bold colours, and strong, disease-free bushes. Picking the right fertilizer doesn’t have to be complicated, and whichever Richgro product you choose, you are assured of the highest quality and effectiveness.

The basics of caring for your rose garden


Caring for your roses doesn’t require too much specialist knowledge to keep them healthy and happy. Just a few simple steps will help you to keep them looking their best.

Watering – Roses need to be watered in hot, dry weather and the frequency depends on how hot, how dry, and the type of soil. A deep soaking every seven to ten days will be sufficient for the majority of dry weather conditions. The water should be applied directly to the soil, not over the whole plant as this can increase problems with disease.

Fertilizing – It is recommended that rose fertilizer is applied every 3 months up until winter to ensure robust plants. It is important to apply in early spring after pruning, during the first bloom period, and then in mid-summer.

Deadheading – This process is designed to encourage growth on re-flowering bushes and involves the removal of faded and dead flowers.
