Eight best fertilizer for roses

1. Jobe’s Organics Flower & Rose Granular Fertilizer

Jobe’s Organics Flower & Rose Granular Fertilizer

This Jobe’s organic fertilizer contains rich organic ingredients like bone meal, biozone products, feather meal, and individually collected and well-processed animal manure. It works well for almost all types of rose plants; planted in pots, garden beds, established plants, and seedlings.

The most highlighted feature of this plant food is the addition of biozone microorganisms which not only helps to break down complex material into simpler ones but also enhances the fertilizer’s NPK ratio. USDA confirms that this product is free of all kinds of chemical contaminations.

The biozone culture possesses archaea that improve the soil quality by adding more nutrients to it, inducing tolerance against pest attacks and weather extremities, and resistance against plant’s contagious diseases.

Applying the fertilizer is also very handy since you just need to mix the recommended quantity with water and pour it around your flowers. You can also sprinkle it over the topsoil every month to trigger flowering.

We also tried this fertilizer for cannabis plants and it worked equally fine to grow exquisite blossoms. The plants showed multiple signs of improvements including faster growth, greener leaves, luscious foliage, and stronger roots in just a few days which was really impressive at this tiny cost.

  • Contains biozone blend
  • Fast-acting and easy to use
  • Improves soil quality
  • Imparts a quick boost
  • Budget-friendly
  • Safe towards kids and pets
  • Smells fishy

Due to having an all-organic nature, you don’t have to be worried regarding root burn. The only problem is it smells stinkier due to having manure in it. Still, it’s the ideal fertilizer for plants that need a sudden boost up and immense growth.

2. Miracle-Gro Water Soluble Rose Plant Food

Miracle-Gro Water Soluble Rose Plant Food

It has been seen that the tiny or newly planted plants show signs of destruction when granular fertilizers are applied to them. The reasons for doing so are numerous including compaction of the soil, interaction of heavy chemicals with the fragile roots, and many others.

In such circumstances, water-soluble fertilizer is mostly recommended since it interacts with the delicate roots of newly planted plants in dilute form and delivers the nutrients in the quantity that is optimally required.

This miracle-gro water-soluble plant food works similarly. You need to dilute the fertilizer first by mixing it with water and spraying it all around the flowering plants using a sprinkler hose or watering can. In this way, your plants could take up the nutrients quickly and show visible results.

We also applied this plant food in the same manner to our garden beds two times; once a week, and were amazed by seeing the quick outcomes like shiny foliage, super-fast growth, and maintaining the plant’s health.

If we talk about the composition and class of this fertilizer, then it possesses almost all the inorganic ingredients including copper, ammonium sulfate, potassium, phosphate, zinc sulfate, iron, and manganese, which makes it somewhat, harmful to kids and pets.

Due to having a high amount of magnesium, your young plants will grow new buds and cans more rapidly.

  • Fast-acting and inorganic
  • High NPK ratio
  • Easy to use
  • Best for newly planted or young plants
  • Small bag
  • Not safe towards pets and kids

The 18-24-16 NPK ratio is seriously so alluring if you want to cultivate roses for commercial purposes. Likewise, this fertilizer is perfectly suitable for the plants grown in beds, borders, and containers; both indoors and outdoors.

3. BioAdvanced Bayer Advanced All in One Rose and Flower Care Granules

BioAdvanced Bayer Advanced All in One Rose and Flower Care Granules

As the name implies, this rose and flower granular fertilizer is designed to provide all sorts of care and maintenance to your flower garden by delivering everything that is required.

Your plants are frequently getting attacked by pests and diseases, this plant food has a solution! Your entire harvest is getting ruined due to fungal diseases, here’s your cure! Your plants are not growing normally, this fertilizer is a life-saver in this situation as well!

All in all, there’s not a thing this plant feed doesn’t cover. How is it being way too versatile? Let’s make it clear by discussing its composition. First thing first, this bioAdvanced flower care feed is a synthetic fertilizer, loaded with chemicals. However, that’s also for a good reason and on opening the packet, we didn’t smell the intense chemical fragrance. One packet is enough to feed about 30-32 rose plants and a one-time application is enough for six weeks.

A synthetic fungicide named Tebuconazole gets absorbed into the soil of your landscape fully. When plants take up this fungicide, it develops the resilience to fight over the fungal diseases within their bodies. In the same way, if a fungal infection is spreading in your harvest and you apply this granular fertilizer to the soil, your unaffected plants will get saved.

Now comes the problem of the retarded plant’s growth. I briefly go through the product composition and also witness the immense growth in my garden’s plants by myself. I came to the conclusion that it’s the phosphate that triggers the healthy cell division which in turn, leads to the desired plant’s growth.

In addition to phosphate, the other two most essential nutrients; nitrogen and potassium, are also present in bulk in the composition making it the best fertilizer for roses and other popular flowers like hibiscus, azaleas, iris, rhododendron, camellias, and many others.

Not only the fungal diseases, but the nearly balanced NPK ratio of 9-14-9 also prevent your plants from catching other widespread diseases like scab, petal blight, rust, powdery mildew, and leaf spot.

  • Contain safe fungicides
  • High NPK ratio to boost growth
  • Develops resistance against pests and diseases

4. Miracle-Gro Plant Food Shake ‘N Feed Rose and Bloom

Miracle-Gro Plant Food Shake 'N Feed Rose and Bloom

It’s another organic fertilizer from the miracle-gro brand that mainly serves the purpose of blooming more flowers and developing richer hues and fragrances in them.

This plant feed mainly works by delivering the food to the already existing microbes of the soil so they can work better to improve soil quality and nutrient content.

The main ingredients of this fertilizer are bone meal, feather meal, kelp, and earthworm castings. Plus, the NPK ratio is 10-8-9 and suitable for both newly planted and established plants.

The composition cannot be classified as all-organic since it possesses some amounts of processed products. Due to being granular, it takes a little more time to break and become a part of the soil. Thus, it works as a slow-acting fertilizer and its one-time application is enough for two to three months.

When the microbes take in this rich nutrient-filled natural feed, they get potent enough to break down the unprepared and complex materials into simpler and prepared ones readily.

When plants absorb more and more nutrients, they not only get stronger and grow better outwardly but also show better growth inwardly. The root system gets fully developed which better the plant’s water intake and balances moisture level.

  • Effective for two to three months
  • Easy to apply
  • Promote inward and outward growth
  • Doesn’t smell bad
  • Improve soil’s nutrient content
  • Not safe for kids and pets
  • Overdo can harm your plants

Due to being synthetic fertilizer, it doesn’t smell stinkier but might harm kids or pets on being engulfed. You don’t need to mix or dilute it in water. Just shake the content, open the cap, and sprinkle around the bases but make sure not to pile the granules up around the shoot since it can damage or burn plants.

Dr. Earth Organic 3 Rose & Flower Fertilizer

For all those looking for an environmentally friendly and 100% organic rose fertilizer, this Dr. Earth plant feed could be proved your best friend as all it possesses is organic. Its NPK ratio is 5-7-2 which is relatively much lower than that of synthetic fertilizers but that’s acceptable.

Its list of ingredients says that this plant food doesn’t contain chicken manure or any other sewage waste. Despite consisting of a very heavy amount of forest products, multi-minerals, humic acid, carbohydrates, proteins, and probiotic organic strains, it smells fishy.

This fertilizer possesses Trubiotic technology that mainly works to break the soil nutrients into smaller ones which, in turn, improves soil’s fertility and increases the number of nutrients in it by releasing micro and macronutrients in it.

The mycorrhizal culture induces resistance against drought and other weather conditions and makes them bloom to the fullest. Since rose plants need more moisture for proper growth, the mycorrhizal fungi partner with plant roots and arrange water and essential nutrients for them.

For better outcomes, you should try to maintain the moisture level around the bases of roses by watering the plants on time and adding good-quality mulches to your flower beds.

You can use this fertilizer as per your choice; by mixing it with water in liquid form or digging into the soil. One-time application is enough for several months. This plant feed also showed impressive results with other annuals, perennials, shrubs, and vegetative plants.

Along with these essential macronutrients, the product possesses fifteen nutrients that play a very constructive role to make your rose garden full of alluring, bulky, and glossy roses.

For example, calcium strengthens the cell wall. Similarly, magnesium assists chlorophyll to capture sunlight and accelerate the rate of photosynthesis.

Due to the presence of humic acid, these nutrients are readily taken in by the plant’s roots and they start to show more signs of improvement in lesser time.

In addition to imparting nutrients, this chemical-free fertilizer also develops resilience against fatal diseases. Using this fertilizer is also quite hassle-free since you just need to sprinkle it over the soil; no digging, no mixing.

Buying guide

There’s a huge misconception about the growing roses that this plant requires immense care or needs way too many nutrients to grow. However, the truth is far different and roses are one of those plants that are easiest to grow.

The reason is that they are highly dormant and possess a tendency to grow newer, greener leaves even if they remain detached from the base for days. That’s why choosing the best fertilizer for roses is not a big challenge if you know some basic soil, watering, and nutrient requirements.

Start with the soil conditions, then just like other plants, roses also love loose soil; one where the air can flow easily and water drainage is excellent.

Thus, the very first thing to consider while buying fertilizer for roses beds is that it should not possess a larger block of perlite or any other bulky ingredient which could clog the soil.

Similarly, go for the fertilizer that maintains the pH of the soil in acidic regions. The soil pH where the rose plants grow perfectly and exponentially is 6-6.5. If we talk about the watering conditions, then as mentioned before, roses love moisture but that doesn’t mean you buy a fertilizer that turns soil completely clogged.

Remember, your fertilizer should act to better the soul quality by enhancing the flow-through and drainage. The texture of soil should get airy enough so water can travel to the deepest root and your plants won’t get exposed to any drought-like conditions or fungal infection.

Lastly, organic fertilizers are mostly preferred for rose plants since they deliver everything to these gorgeous plants without being hard on their fragile stems and roots. However, organic plant food smells fishy which makes them a bad choice to be used for indoor plants.


You can use almost all the organic stuff, including organic waste products, as a natural fertilizer to nurture your rose plants. The most common natural fertilizers are eggshells, fishbone meals, pet food, tea leaves or tea bags, and fruit peels.

The best time to fertilize your rose plants is the spring since that’s the part of the year wherein plants grow to their fullest and it needs external help for this growth.

Summer, fall, and winter are counted as the periods of dormancy for the rose plants so you better stop fertilizing them before these seasons.

Potassium is the main reagent that triggers the blossom formation in plants thus, all those fertilizers having a rich amount of potassium in them, are ideal to induce blooming.

Final thoughts

Roses are one of those plants that can be grown in almost any type of weather since they possess an intense level of dormancy in them. However, it’s only possible if it gets external aid during the non-dormant period of the year which can act as a supplement or growth booster.
