In order to produce the greatest blooms, roses, which are heavy feeders, need a variety of nutrients throughout the growth season. The best results are therefore obtained by fertilizing your rose bed with a variety of organic fertilizers.
For the greatest results, fertilize roses organically once every four weeks during the growing season using a mixture of fish emulsion, blood/bone meal, and alfalfa. You can also occasionally add Epsom salts to encourage basal breaks. Different organic fertilizers encourage the ecology of the soil and supply all the nutrients required for roses to develop robustly and healthily with an abundance of blossoms.
While chemical fertilizers are similar to multivitamins in that they enhance nutrient levels without contributing to the long-term fertility of the soil, natural, organic fertilizers function like a healthy, balanced diet.
Alfalfa, fish emulsion, regular mulch, and blood/bone meal are examples of organic, natural fertilizers that are better for the environment because they not only feed the rose directly but also enhance the soil’s long-term health and fertility.

1. Mulching as Fertilizer for Healthy Roses
The easiest technique to preserve soil health and organically contribute nutrients to the earth is to spread mulch around the base of roses twice a year.
In order to grow strong, disease-resistant roses, the rose bed should have mulch added to it rather than just feeding the plant directly.
In addition to providing nutrients, leaf mould, well-rotted horse dung, worm castings, grass clippings, and compost all enhance the soil’s structure and support its ecology.
Well-rotted horse dung is very beneficial for improving soil because it is bursting with energy and provides the nutrients phosphorus, nitrogen, potassium, and phosphate needed to grow healthy roses.
As a result of the manure’s prolonged breakdown and gradual release of nutrients, water-soluble components like potassium are progressively given to the soil as opposed to being washed away by the initial period of heavy rain as they are with chemical fertilizers.
The soil’s microbial population, including good bacteria, fungus, and earthworms, is revitalized by manure. Earthworms eat organic matter that is degrading as well as extremely fertile, nutrient-rich worm castings.
Your roses will enjoy worm castings since they are a digested, highly concentrated bundle of nutrients that are simpler for the roots to absorb.
You can use well-rotted horse dung, which is crumbly in texture and has lost its scent, as mulch around your rose bushes in the spring if you have access to it.
However, it is a terrific idea to add the manure to your compost pile if it still smells. You may use your compost more quickly because of the energy and bacteria in the manure, which also help to heat up the pile.
The spread of the foul smell of manure can be immediately stopped by adding brown materials to your compost, like cardboard, dried leaves, and shredded paper.
Fresh horse manure can burn the roots of roses and other plants during the decomposition process, therefore you must wait for it to rot down into a decomposed condition.
When to Apply Mulch to Roses
I advise applying mulch at least twice a year for best results.
- The first application ought to be made in the spring, at the commencement of the growth season. Throughout the growth season, this will enable the mulch to decompose and release nutrients into the soil. In addition to keeping the rose’s roots cool, mulch improves soil structure for better drainage, aids in water retention, and controls weed growth.
- Before the onset of winter, at about the end of September, the second application should be completed. This provides your rose a jump start the next spring by protecting the roots from the coldest temperatures and allowing them to recover winter damage.
As organic matter has a considerably higher ability to absorb water than most soils do, I add another layer of mulch if the summer is extremely hot so that the roots may draw on this moisture when they need to, preventing drought and keeping the roots cool.
Mulch can be spread over the soil at any time to mask the smell of other organic fertilizers like fish emulsion and bone meal.
Applying mulch to rose bushes
Mulch should be applied in a 2 inch layer around your rose bed. There is no need to dig it in because doing so will disrupt the soil’s ecosystem and you risk damaging the roses by using your spade to sever their roots.
Simply put the mulch around the base of the plant and let rain and worms gradually incorporate it into the soil.
Make sure there is 5 to 6 inches of bare ground between the mulch layer and the rose canes that poke through the ground. The above-ground wood of roses does not withstand prolonged exposure to damp organic substances since this can cause rot.
2. Alfalfa for Fertilizing Roses
Long a favorite of organic gardeners, alfalfa is a common natural fertilizer that is frequently the major component of readymade organic fertilizer blends.
Alfalfa is a good source of nitrogen, magnesium, phosphorus, iron, calcium, and zinc, all of which nourish and encourage rose bushes’ healthy growth and a profusion of flowers.
With some chemical fertilizers, the water-soluble nutrients can get washed away after watering or heavy rain, so there is less time for the roots to take in the nutrients and the product is essentially wasted. I personally use alfalfa in pellet form because it decomposes over time, gradually releasing the nutrients into the soil to benefit the rose throughout the growing season.
Triacontanol, a growth promoter found in alfalfa, is prized for its ability to enhance the number of basal breaks on rose bushes. Basal breaks are highly valued by rose gardeners because they allow for the emergence of new canes that eventually replace older, spent canes when it comes time to prune your roses. New canes yield more blossoms.
How and When to Apply Alfalfa For Roses
From the beginning of spring through the middle of august, alfalfa can be applied once per month during the growing season to help any new growth firm up before the winter hibernation.
I personally spread alfalfa pellets on the ground in April or May (when the rose bush’s leaves are unfurling) before covering the area with mulch and giving my rose shrub a thorough bath with the soaker hose (or 4 gallons with a watering can).
The next month, I simply rake the mulch to one side, distribute a few alfalfa pellets over the soil, and then reapply the mulch with the rake to promote decomposition and ensure that the nutrients reach the roots.
Digging it into the soil is not necessary because they breakdown and the nutrients get to the roots when you water your roses. Digging is not only pointless, but using the spade will also slightly harm the roots of the rose.
3. Epsom Salts for Roses
Because magnesium is not always readily available in the acidic soils preferred by rose bushes or as a result of soil erosion, there may be a magnesium deficiency in the soil.
High magnesium content in epsom salts is thought to help plants grow more flowers, stronger canes, and greener foliage.
Application of Epsom Salts for Roses
Epsom salt application is really simple. You only need to apply half a cup annually in the spring when the weather starts to warm up to your rose bush. Simply combine your half cup with water in a 2-gallon watering bucket before sprinkling it around the rose’s base.
However, you should absolutely forgo this fertilizer if your plant soil has a high salinity level. Salt can build up in gardens with heavily compacted soil (like clay) and poor drainage, which can impede plant growth.
This is unlikely to be an issue if your soil drains effectively and has a lot of organic matter.
4. Blood and Bone Meal for Fertilizing Roses
A powdered by-product of slaughterhouses, blood and bone meal is used in cooking. It has a healthy amount of iron, which is necessary for photosynthesis and aids in the production of chlorophyll in the leaves, as well as a good concentration of nitrogen to green the foliage and encourage new development.
Additionally, it is a particularly good fuel for the ecology of the soil, which in turn breaks down organic matter and increases the availability of nutrients in the soil, allowing your roses to grow stronger, produce more flowers, and be more disease-resistant.
Obviously, if you oppose the usage of animal products, you should steer clear of this one. There are plant-based alternatives that offer comparable levels of nitrogen, so omitting bone meal and fish emulsion shouldn’t be an issue if you consistently apply other plant-based fertilizers (such alfalfa, manure, and coffee grounds).
Application of Blood and Bone Meal for Roses
You must be careful when applying bone meal because cats, dogs, and possibly other animals that frequent your garden may find the smell alluring.
The best method is to remove any soil or mulch that is covering the rose bush, apply bone meal directly to the ground, and then reapply soil and mulch on top. Finally, you need to give the rose bush a particularly good long, slow soak, preferably with a soaker hose because it will need several watering cans’ worth of water.
Mulch and moderate watering work well together to keep odors to a minimum, reducing wildlife attraction and allowing bone meal to penetrate the soil and reach the roots.
Additionally, bone meal will aid in enhancing the soil’s structure for enhanced drainage and reduced soil compaction.
Once a month beginning in March, you can apply bone meal to the soil; however, after August 15th, you shouldn’t do so because the plant needs to focus its energy on preparing for winter rather than promoting development.
5. Fish Emulsion For Fertilizing Roses
A fantastic resource for organic fertilization is fish emulsion. This is due to the fish emulsion’s 5% nitrogen concentration, which nourishes the plant immediately and encourages fresh, vigorous growth in the spring.
All plants require this crucial ingredient to produce chlorophyll in their leaves and promote photosynthesis. For increased flower production and disease resistance, it also has potassium and phosphate.
It also acts as a tonic for the soil, encouraging the activity of bacteria that help decompose organic matter and release nutrients that are beneficial to the rose bush.
The health and disease resistance later in the season are improved by using fish emulsion once a month in the spring.
Fish emulsion has the advantage over other fertilizers in that it will go to the roots more quickly. This is why it works so well to provide a variety of nutrients throughout the growth season when used in conjunction with slow release fertilizers like alfalfa.
How and When to Apply Fish Emulsion for Roses
Fish emulsion’s disadvantages are the animals it attracts and the strong, disagreeable odor it emits. Since its smell is attractive to cats, dogs, and flies alike, you must exercise caution when using it.
The most popular recommendation is to mix one tablespoon of fish emulsion with one gallon of water in your watering can, though you should always follow the label’s directions.
Simply soaking it in around the base of your rose will serve as application.
The ideal method is to rake any mulch you have put down around the rose to one side, apply the emulsion, and then rake the mulch back into place, as is the case with all stinky fertilizers.
This works well to absorb the odor and, with any luck, deter any curious wildlife.
As the emulsion seeps into the soil to reach the roots and as a result has a much weaker odor than fish meal, which can take a while to break down and lose its odor, I personally prefer fish emulsion that can be diluted into water instead of powdered fish meal.
Use this fertilizer once a month in the spring (starting in April/May), and make your final treatment before August 15th to avoid encouraging new growth right before the onset of winter.
Banana Peels For Fertilizing Roses
As simple as it may sound, you can just plant your rose on top of a banana peel that has been thrown into the hole you have dug for it.
– BEST GRANULES: Down to Earth Organic Rose & Flower Fertilizer Mix.It goes without saying that if you oppose the usage of animal products, you should avoid this. Skipping bone meal and fish emulsion shouldn’t be an issue if you consistently utilize other plant-based fertilizers (such alfalfa, manure, and coffee grounds), as there are plant-based alternatives that contain comparable levels of nitrogen.
You must be careful in your application because the smell of bone meal may be seductive to cats, dogs, and possibly other animals that frequent your yard.
The best method is to remove any soil or mulch that is covering the rose bush, apply bone meal directly to the ground, and then reapply soil and mulch on top. You then need to give the rose bush a particularly good long, slow soak, preferably with a soaker hose because it will need several watering cans’ worth of water.
Conclusion
Mulch and gradual watering work well together to reduce odors, which deters wildlife and facilitates the penetration of bone meal into the soil and up to the roots.
Additionally, bone meal will aid in enhancing the soil’s structure to facilitate easier soil compaction and greater drainage.
Once a month beginning in March, you can apply bone meal to the soil; but, after August 15th, you shouldn’t do so because the plant needs to focus its energy on getting ready for winter rather than on promoting growth.
Your toolbox for organic fertilizing should include fish emulsion. The reason for this is because fish emulsion has a 5% concentration of nitrogen, which nourishes the plant immediately and encourages fresh, robust growth in the spring.
This is a crucial ingredient that all plants require in order to produce chlorophyll in their leaves and promote photosynthesis. Additionally, potassium and phosphate are present for increased floral production and disease resistance.
It is also a tonic for the soil since it encourages the activity of soil bacteria, which aid in the breakdown of organic matter and the release of nutrients that benefit the rose bush.
To improve health and disease resistance later in the season, fish emulsion should be applied once per month in the spring.
