Is Rose Fertilizer Good For Other Plants

Rose fertilizer is popular among growers to help maximize the growth and beauty of their rose bushes. And, although such fertilizer is specifically formulated for roses, there has been a rising interest in using it for other flowering plants.

So, is rose fertilizer good for other plants? The short answer is yes – rose fertilizer can be used not just for other flowers, but even for some varieties of vegetables. It is rich in macro- and micronutrients, which means it will benefit most plants. 

Below, you will find a short guide to rose fertilizers and why they might be beneficial for your other garden plants.

What is rose fertilizer?

In a nutshell, a rose fertilizer is a type of organic or inorganic food formulated specifically for rose bushes. Fertilizer companies produce this fertilizer to help rose growers provide for the nutritional needs of their plants.

Rose fertilizers contain almost the same macronutrients as the other plant fertilizers available on the market. Roses need a specific ratio of nitrogen, phosphorus and potassium (NPK ratio) in order to grow and bloom beautifully. Different fertilizers contain different NPK ratios, according to the varying requirements of different plants. For example, a package might indicate a 6-12-6 NPK ratio, which means it contains six percent nitrogen, 12 percent phosphorus, and six percent potassium.

Ideally, roses need other nutrients, too, to encourage healthier and more abundant blooms. Depending on the rose variety, the flower will require a precise combination of elements such as calcium, boron, copper, iron, cobalt, magnesium, zinc, sulfur, and manganese.

Overall, then, there is nothing very special about rose fertilizers, since they are formulated with almost the same nutrients to support plant growth. Some packs might come with different nutrient combinations to support a specific variety of rose. Rose fertilizers can also be combined with organic fertilizers to promote healthy, vigorous blooming throughout the growing season.

Is rose fertilizer good for other plants?

You might have a few doses of rose fertilizer left over and are wondering if you can use them for your other plants as well. Here is the good news – rose fertilizer can be great for other plants. Just like other commercially available plant fertilizers, rose fertilizers contain all the essential nutrients. Whether you want to give a boost to your indoor plants or your vegetable garden, that rose fertilizer can come in handy.

The important thing to keep in mind is that rose fertilizers contain nitrogen – a nutrient known for its acidifying properties. Hence, the higher the nitrogen content in a fertilizer, the more acidic the fertilizer will be. Acid-loving plants like grass and citrus trees will especially appreciate this type of growing medium. 

Rose fertilizers, as mentioned before, are also formulated with phosphorus. This macronutrient is the main ingredient that makes most flowers bloom. If this is the result you prioritize for your plants, then this type of fertilizer could be beneficial. Potassium-rich compost, on the other hand, will assist in the fruiting stage of your plants.

There are many brands of rose fertilizers you can choose from, with Miracle Gro Rose Food being one of the most popular among gardeners. But remember to do your own research before using rose fertilizer on your plants. Some growers might prioritize healthier foliage, while others prioritize the beautiful blooms of their plants. If you apply the wrong type of fertilizer, you might not achieve your desired results!

As mentioned previously, rose fertilizers come in different formulations. To use them effectively on your plants, make sure to follow the recommended dosage on the package. Always remember that too much fertilizer can burn the roots and might even kill your plants!

Benefits of using rose fertilizer on plants

Rose fertilizer can be beneficial for your plants in several ways. It is engineered to enrich plants and vegetables with all the important nutrients to support healthier growth and stronger roots. Using rose fertilizer can also increase your plants’ resistance to many plant diseases, thereby increasing the size and quality of your yield. 

You can also apply rose fertilizer to increase the size of your fruit and enhance the taste. Just make sure to apply the fertilizer to moist soil to ensure proper absorption. You can also combine this with organic compost so that your plants have multiple nutrient sources.

Can you use rose fertilizer for vegetables?

Rose fertilizers are high in nitrogen, phosphorus, and potassium, all of which are essential for garden crops. So, yes – it is possible to use them on your vegetables. But of course, there are some important factors you need to consider to ensure that they will work well for your garden.

First and foremost, most vegetables in their earlier stages of growth might not benefit from rose fertilizer. That is because young vegetable plants need to focus most of their resources on root development. Hence, the best option for growing your veggies at this stage would be to use mulch and organic compost. You should also give your plants a sufficient amount of water and sunlight for them to grow well.

Once your crops are fully established, then you may use rose fertilizer to add supplementary nutrients to the soil. As we have mentioned earlier, some rose fertilizers are formulated with a high nitrogen content, which means they are more beneficial for acid-loving plants. Some vegetables that thrive in acidic soil include cucumbers, tomatoes, parsley, radishes, peppers, and potatoes. Make sure to do your research to properly understand the unique needs of your individual plants.

Can you use rose fertilizer for other flowers?

Rose fertilizer is nutritious for other flowering plants, too. Depending on the variety, this type of fertilizer might help you achieve larger and more beautiful blooms. Other benefits of using rose fertilizer include rapid growth, stronger and more flexible stems, and improved resistance to common pests and diseases.

Again, knowing the formulation of a particular brand is key to successfully using it on your flowering plants. For example, you can apply a 9-14-9 NPK ratio on your hydrangea for about six weeks to promote abundant blooms. You can also add peat moss and vermiculite to the soil during springtime for larger, healthier flowers. 

Aside from adding color to your garden, you can also use rose fertilizer to enrich your lawn and garden beds. Make sure to follow the dosage recommended on the packaging for the best results.


While rose fertilizers are formulated for growing different varieties of roses, they can also be beneficial and safe for other plants. Whether you are growing vegetables or other types of flowers in your garden, your priority is to determine the specific needs of your plants. This way, you will know whether supplementing them with rose fertilizer would be beneficial, or whether it is better to stick with your traditional organic compost to fulfill their nutritional needs.
