Frequently Asked Questions (FAQs)

1. What is the best fertilizer for roses?

FOR ESTABLISHED ROSES: Use a high-nitrogen fertilizer or top dress with alfalfa meal (5-1-2) for the first application to jump-start leaf development, along with epsom salts to encourage new cane development and lusher growth. Add a slow-release fertilizer when shoots are 4 to 5 inches long.

2. What is the best time to fertilize roses?

When and How to Fertilize Roses Start feeding older plants in spring when new growth is about 6 inches long. Most will benefit from a second feeding of liquid fertilizer after the first bloom, and repeat-blooming roses do best with regular feeding every 2-3 weeks until late summer.

3. How often should you feed roses?

Feeding your roses twice a year will encourage strong, healthy growth and abundant flowering. It's a relatively quick and simple task, yet is one of the most beneficial jobs you can do to ensure that your roses are at their most healthy and floriferous when summer arrives.
