Because roses are heavy feeders, fertilizer is a vital element of rose care. Make sure to fertilize regularly. You should fertilize your roses regularly if you want to see their glossy leaves and vibrant flowers.

You should keep in mind that too much nitrogen will lead to excessive foliage and fewer blooms. A lack of nitrogen will cause yellowing leaves, stunted growth, and smaller blooms.

Roses can be sensitive to fertilizers while young. Still, sufficient nutrition supports growing roots and helps create new roses throughout time, so you must use the right fertilizer to meet their needs. But what is the best fertilizer for roses and which nutrients should be in those fertilizers is fundamental.

So, let’s start with the question: What nutrients should be in the fertilizer, and what should be remembered when buying?

Without phosphorus, it can cause leaf drops, weak flower stems, and closed buds. Phosphorus promotes healthy root development and large flower production, and nitrogen promotes leaf growth that is strong and healthy. 

Because a rose’s power to produce flowers is housed in its leaves, nitrogen makes healthy foliage, increasing the number of blooms.

Potassium, commonly known as potash, aids in the recovery of roses that have been damaged by insects, diseases, or harsh weather conditions. Potassium deficiency can cause yellowing of the leaf margins, brittle flower stalks, and underdeveloped buds.

Macronutrients include magnesium, calcium, boron, zinc, sulfur, copper, manganese, and iron is also necessary to thrive well in a rose. 

But all constituents should be in balance; thus, examine fertilizers NPK ratio, which displays the percentage of its volume provided to nitrogen, phosphorus, and potassium. Generally, an N-P-K ratio of 1-1-1 is advised for roses.

Now, my friend, we are just getting started. We will show you some of the best and suitable fertilizers to help your geranium get more healthy.

How to Decide which Rose Fertilizers Are the Best?

Choosing the best fertilizer for your roses isn’t as easy as it may seem.

You can choose between inorganic and organic fertilizers as well as granular, liquid, water-soluble, or plant food in pre-measured spikes.

While this is a matter of your preference and it doesn’t necessarily affect the growth of the plants, the most important part of your decision making should be the nutrients that the fertilizers can provide to your roses.

When choosing the best rose fertilizers, you should keep in mind the season, as well as the state of the soil and overall climate conditions in the area you live in.

Having said that, no matter if you’re looking for the best type of fertilizer for roses in summer, winter or spring, you should know which nutrients to look for in order for your plants to be fed successfully so that they can grow strong and lush.

The three most important nutrients for roses are nitrogen, phosphorus, and potassium, and you’ll usually see their ratio in N-P-K form (where letters are replaced by the numbers).

Other than these three, your ideal organic rose fertilizer should also consist of the following nutrients: Zinc, Boron, Calcium, Sulfur, Copper, Magnesium, Iron, and Manganese.

Keep in mind that young roses are usually better off with liquid fertilizer and don’t really benefit from the granular one.

The Best Way to Fertilize Rose Plants

Before we even speak about how to fertilize roses, you have to make sure that the pH level of the soil is right. Roses thrive in the 6-6.5 soil, and that’s when you can add the rose food.

Other than that, you should also know that the best results are achieved if you change the type (consistency) of organic rose fertilizer every once in a while. Start with the liquid version, and they change up a bit by using food granules, and similar.

Each type of fertilizer you purchase should have clear instructions on how to use it. Still, you’ll find the majority of them very intuitive and easy to use.

Rose food that is soluble in water will need to be mixed with water and applied like that.

Granular and similar solid forms of fertilizer are usually added according to the instructions, worked into the soil on the bottom of the plant with a gardening tool, and then watered thoroughly.

How Frequently to Use Rose Fertilizer?

How Frequently to Use Rose Fertilizer?

Too little or too much fertilizer can be equally damaging to your roses.

If you use too much of it, you risk burning your plants. On the other hand, too little fertilizer won’t have any effect because it won’t feed the plants sufficiently.

For this reason, it’s very important to establish a good schedule of feeding your plants and monitor the reaction to different fertilizers.

This, of course, depends on a couple of factors.

As you can probably conclude from the product reviews, the first one would be the type of fertilizer you use.

While granules and spikes are usually fertilizers that release nutrients slowly, and they are typically reapplied every six to eight weeks, liquid fertilizers give an instant boost and feed your roses quickly.

This means that you’ll need to use them every week.

Another essential aspect to keep in mind is the state and consistency of the soil. Sandy and soft soils will need more frequent fertilizing as opposed to loam type soils.

Manufacturers try to give detailed instructions on the back of the packaging, but still, follow the plants’ consumption and adjust the frequency of using the fertilizer according to that.

When to Fertilize Rose Plants?

As the last thing in this article, we should also mention the best time to fertilize roses.

You probably already know that roses grow during the winter, and it is very important to keep them strong and healthy because of the harsh temperatures.

That’s why it’s crucial to add fertilizers rich with nitrogen during fall since this nutrient is very beneficial to the roots of the plant.

This will make sure your roses have strong roots and resist lower temperatures during winter.

Once the winter is over, you can again introduce fertilizers after the first weeks of spring.

Having said that, the most reliable thing to do is follow the state and growth of your plants in order to adjust the use of plant food according to the overall conditions of the weather, soil as well as humidity.


  • Why is fertilizer necessary in planting?

The world’s crops, like ourselves, rely on crucial minerals and nutrients for strong, healthy growth. Crops consume the soil of nutrients, which fertilizers provide. Crop production and agricultural output would suffer dramatically if fertilizers were not used.

  • What is a good NPK ratio?

Keep in mind that the number of existing soil nutrients must be considered while calculating this. Many soils already have an adequate amount of phosphate. Thus additional fertilizer isn’t necessary. Potassium levels in your soil may be appropriate as well. A 3-1-2 NPK ratio is ideal for your garden, pots, and indoor plants.

  • How do I make my geranium bushy?

A geranium needs to be clipped firmly at least once a year to keep it compact and bushy and to avoid it becoming lanky. The more often you prune your geranium, the better it will preserve its attractive form.

  • What kind of fertilizer makes flowers bloom?

Use a fertilizer with a low nitrogen content, a high phosphorus content, and a small amount of potassium to increase floral bud formation. I recently bought a liquid fertilizer with nutrient analysis of 5-30-5, perfect for flower production.

  • How do you increase the production of a flower?

The flowering stage is the most critical for providing CO2 to your growing environment. CO2 can help jump-start floral production and increase blossom size by as much as 300% in the first 2-3 weeks of flowering. If you want your plants to thrive, use Exhale CO2 bags to naturally supply them with more CO2.

Final Word

Most of the fertilizers on our list of the 9 best rose fertilizers are organic these days. Most gardeners want a fertilizer that contains all the specific nutrients needed by roses, and this one delivers on both measures.

Whether you’re a dedicated specialist rose grower or a sunny weather gardener looking for easy fertilize-and-forget rose food, our collection has something for you.

But before choosing, we advise getting your soil tested first before deciding on organic or synthetic fertilizer and what type of NPK mix you require. As a result, think about the N-P-K ratio of your trees’ nutritional needs.
