How to Fertilize Roses: A Comprehensive Guide
How to Fertilize Roses?
To fertilize roses, it is important to provide them with a continuous source of nutrients throughout the growing season.
The primary nutrients roses need are nitrogen, phosphorus, and potassium.
Nitrogen promotes leaf growth, phosphorus promotes root development and flower production, and potassium helps roses recover from stress.
Additionally, roses require micronutrients such as calcium, magnesium, and zinc.
For newly planted roses, the planting hole should be amended with organic matter and slow-release fertilizer, with Epsom salts sprinkled around the base of the plant.
Fertilize every 3 to 4 weeks with a mild fertilizer.
Established roses should be fertilized when new leaves emerge with a high-nitrogen fertilizer or alfalfa meal, adding slow-release fertilizer when shoots reach 4 to 5 inches long.
Continue fertilizing every 2 to 4 weeks during the growing season, applying a slow-release fertilizer with low nitrogen content in late summer to early fall.
It is important to stop fertilizing 6 to 8 weeks before the first frost date.
Container roses may need more frequent fertilizing due to nutrient leaching.
Organic fertilizers derived from plant or animal matter are recommended as they are better for the environment.
Compost, manure, bone meal, cottonseed meal, kelp meal, and fish fertilizer are all examples of organic fertilizers that can be used for roses.
Coffee grounds can also be sprinkled around the base of rose bushes for a boost of nitrogen.
It is important to be mindful of soil pH and adjust it as needed.
Water roses before and after fertilizing to prevent root burn or shock.

It helps roses establish strong and healthy root systems, allowing them to anchor firmly in the soil and absorb nutrients efficiently.
Potassium is another essential nutrient for roses as it aids in their ability to recover from stress. This nutrient helps roses combat various environmental factors such as heat, cold, and drought. It strengthens the rose plants, ensuring they can withstand these challenges and continue to thrive.
In addition to these primary nutrients, roses also require various micronutrients such as calcium, magnesium, and zinc. These micronutrients are necessary for the overall health and well-being of roses, contributing to their disease resistance, flower color, and vigor.
Fertilizing Newly Planted Roses
When planting roses, it’s important to provide them with a good foundation for growth. The planting hole should be amended with organic matter to improve soil structure and fertility. Adding slow-release fertilizer to the planting hole will supply the roses with a steady stream of nutrients as they establish their root systems.
Epsom salts, rich in magnesium, are also beneficial for newly planted roses. Sprinkling a small amount of Epsom salts around the base of the plant will promote bloom color, greener foliage, and more vigorous cane growth.
To ensure continuous nutrient supply, newly planted roses should be fertilized every 3 to 4 weeks with a mild fertilizer. This regular fertilization routine will support their growth and help them adapt to their new environment.
Fertilizing Established Roses
Established roses require consistent fertilization to maintain their health and vigor. The fertilization schedule for established roses varies depending on the growth stage and time of year.
When new leaves start to emerge in the spring, it’s time to fertilize established roses. High-nitrogen fertilizers or organic options like alfalfa meal are excellent choices at this stage. These fertilizers will provide the roses with the necessary nutrients for lush growth.
As the shoots reach a height of 4 to 5 inches, it’s time to add slow-release fertilizer to further support their growth. This type of fertilizer provides a sustained release of nutrients, ensuring the roses receive a continuous supply throughout the growing season.
Continuing the fertilization routine every 2 to 4 weeks during the growing season will help established roses maintain their beauty and vitality. However, it’s important to note that fertilizing should be stopped 6 to 8 weeks before the first frost date to allow the roses to prepare for dormancy.
- Use high-nitrogen fertilizers or organic options like alfalfa meal in the spring.
- Add slow-release fertilizer when the shoots reach a height of 4 to 5 inches.
- Continue fertilization every 2 to 4 weeks during the growing season.
- Stop fertilizing 6 to 8 weeks before the first frost date.

Organic Vs Inorganic Fertilizers For Roses
When it comes to choosing the right fertilizer for roses, gardeners have two primary options: organic and inorganic fertilizers. Each has its advantages and considerations.
Organic fertilizers, derived from plant or animal matter, are considered better for the environment and can be used alone or in combination for rose fertilization. They improve soil health and fertility, providing long-lasting benefits. Organic fertilizers also tend to release nutrients slowly, ensuring a consistent supply throughout the growing season.
Inorganic fertilizers, on the other hand, are ready-to-use and often less expensive. These fertilizers deliver nutrients quickly and efficiently but do not offer long-term benefits for soil health. Additionally, inorganic fertilizers can have a high nitrogen content, which may not be suitable for some rose varieties or environmental conditions.
It’s important to consider the specific needs of your roses, as well as your personal preferences and gardening philosophies, when choosing between organic and inorganic fertilizers. Both options can be used effectively, but organic fertilizers tend to be more sustainable in the long run.

Frequently Asked Questions
What is the best fertilizer for Rose?
The ideal fertilizer for roses is one that consists of a combination of well-rotted animal manure or compost and blood and bone. It is important to steer clear of manure from animals that have a meat-based diet, as well as to use chicken manure sparingly due to their high acidity, which may not be suitable for roses. The combination of organic matter and essential nutrients provided by this type of fertilizer ensures optimal growth and blooming for these beautiful flowering plants.
What is the best time to fertilize roses?
The ideal time to fertilize roses is early spring when they start to leaf out and display approximately six inches of new growth. It is advisable to water the roses before fertilization, especially if they are dry, as this will help prevent the flowers from absorbing nutrients too rapidly. This strategic approach ensures that the roses receive the necessary nutrients at the right time to promote healthy development and vibrant blooms.
What is the best feed for roses?
For optimal growth and blooming, roses require a balanced feeding regimen. It is advised to begin with a nitrogen-rich feed such as “Blooming Beauty” after the late-winter prune, and continue with a bi-weekly application of a high potash feed like “Blossom Booster” or “Rosy Delight” during the flowering period. The results can be truly astonishing, as evidenced by the remarkable transformation displayed in the accompanying photo.
How do you use NPK for rose plants?
To provide the necessary nutrients to rose plants, NPK fertilizers are used, particularly through a foliar spray method. After repotting, it is crucial to begin the foliar spray as a primary source of nourishment. Once the rose plant is over 10 days old, applying NPK 12:61:0 for a month helps stimulate healthy growth. After this initial period, transitioning to NPK 19:19:19 or 20:20:20 can sustain the plant’s nutritional needs, allowing it to flourish and thrive.
