Nutrients That Roses Need To Grow
So, what exactly defines a formula as the best rose fertilizer? To identify a good fertilizer for your roses, you need to consider the nutrients and macronutrients present in the mix. Following are the primary nutrients that must be present in the best rose fertilizer.
Phosphorus
Phosphorus needs to be present in the formula as this nutrient is crucial to a robust root system. It also controls the production of flowers. A deficiency of this nutrient can prevent flowers from blooming fully. This is a result of an inefficient stem network.
Nitrogen
Nitrogen is key to lush green foliage and a more significant number of flowers. A deficiency of this nutrient will leave your plant with yellow leaves. The plant will also cease to grow to its optimum height and remain a dwarf. In contrast, an excess of nitrogen can cause leaves to grow abundantly at the expense of beautiful, vibrant blooms.
Potassium
Potassium aids in plant recovery. Rose plants use this nutrient to revive themselves after insect attacks and weather hazards. You can quickly identify a lack of this nutrient. It is when your plant’s leaves turn yellow, and you notice underdeveloped buds.
Macronutrients
Minute amounts of other minerals like calcium, zinc, iron, boron, magnesium, and even copper are essential to the proper growth of rose plants. These act exactly like multivitamins for humans. However, instead of daily pills, you can feed your plants a good fertilizer formula to achieve similar results.
How To Choose The Best Rose Fertilizer?
With tons of rose fertilizer formulas available in the market today, it is difficult to decide which one to get. So, what things can you keep in mind to pick out the best rose fertilizer? Keep reading to find out!
All rose fertilizers can be divided into two kinds!
Organic formula
Organic fertilizers are made from all-natural ingredients based on plant and animal derivatives. No synthetic chemicals or compounds are added to the mix. These kinds of formulas are best for organic gardens and plants. These slow-release formulas stay in the soil for more extended periods of time. They steadily provide food and nutrients to your plants over an estimated time span.
Due to being created from all-natural ingredients, these can easily substitute manure or compost. However, the nutrition that’s packed into these formulas is usually lower in concentration. These are also not fast-acting as they take a longer time to decompose.
A few kinds that fall under organic formulas include:
- 3 to 4-day old animal manure
- Bone meal (phosphorus)
- Dry blood meal (nitrogen)
- Greensand (potassium)
- Seaweed (nitrogen)
- Rock phosphate (calcium)
Inorganic formula
An inorganic formula, although artificial, can feed plants more efficiently as compared to organic formulas. These are quick-acting formulas that yield fast results. The reason behind their effective performance is thorough lab tests.
Inorganic formulas are usually very concentrated as compared to organic fertilizers. These will quickly and effectively provide nutrition to your rose plants in a short span of time.
Picking between an inorganic fertilizer or organic formula is entirely based on personal preference. However, if you want to supply a fixed and calculated ratio of potassium, nitrogen, and phosphorus to your plant, you might want to consider inorganic plant food. Furthermore, you can also use inorganic fertilizers to help revive dying rose plants.
How To Fertilize Rose Plants?
Now that you know all about the best rose fertilizer products and how to differentiate and pick one, it is time to look at another important question. What is the correct procedure for the fertilization of rose plants? In this section, we will answer this question and cover more. Let’s get going!
Most garden enthusiasts and plant lovers mix organic and inorganic fertilizers to create their own suitable mix. This works very well as organic formulas are slow-release while inorganic formulas are fast-acting. A combination of these two helps produce fast and long-lasting results.
Below we have listed a few tips you can follow to help promote lush green foliage and vibrant blooms:
- Prep your soil up in early spring. This should be done before planting roses into your garden soil. Organic fertilizers should be used to create a natural mix. This will prevent synthetic chemicals from damaging the immature rose plants, and the plant will get adapted to nutrients being provided slowly.
- Apply chemical or synthetic fertilizers once roses start blooming in the growth season. Always apply your granular mix around the top 6 inches of soil in a circular pattern. This should be started from the base of the rose plant, slowly moving onto the topsoil.
- Liquid fertilizers can simply be poured in a circular pattern on the top 6 inches of soil after dilution.
- Other minerals that you can add to boost rose plant growth include Epsom salts, sulfur, and magnesium.
- Remember to add other minerals only after the plant has received its first round of fertilizer. It is necessary to ensure that the rose plants have adapted to mineral absorption. Furthermore, Epsom salts should always be raked into the soil and watered down for best results.
Organic Fertilizer Recipes
We have listed two organic rose fertilizer recipes below that you can whip up on your own. These are optional and based on preference and plant needs. Make sure to apply the fertilizer in early spring.
Recipe 1
Ingredients:
- 110 grams of Epsom salt
- 230 grams of fish meal
- 110 grams of bone meal
Instructions:
- Mix all ingredients thoroughly. It will have a foul odor, but this is a given.
- Water your plants before application. Add the mix to the plant base and embed it at least 2 inches deep into the soil.
- Water again after application.
Recipe 2
Ingredients:
- Banana peels
Instructions:
- Banana peels are rich in potassium. You can make compost out of these or even directly add them to the soil.
- Banana peels should be buried at least 3 to 6 inches deep into the soil.
- Banana peel powder yields even better results. Simply chop your peels into tiny pieces and run them in a food blender.
- Apply the powder in early spring.
How Often Do I Need To Fertilize My Roses?
Fertilizer application is crucial. Nobody wants to burn or kill off their plants due to over-fertilization. It is always safer to under-fertilize rather than go for scary ratios. Always read all instruction manuals and manufacturer guidelines before applying any type of formula to your rose plants.
Organic fertilizers need to be applied at least once each month during the growing season. Start application in early spring and continue for the next 4 weeks. You can stop after your rose plants become dormant. Later on, when they exit hibernation mode, inorganic fertilizers can be used to treat your plants.
Never apply any formula ahead of time or after the indicated period. Both these practices can severely damage your rose plants. You might also notice weak growth. Furthermore, you should stop all fertilization at least 8 weeks before the first snow.
Fertilization needs also vary depending on where your plant is sown. Rose plants growing in pitted containers need to be fertilized more often. Always make sure to add fertilizer at 3-week intervals. Yellow foliage will indicate that your plant is running low in nutrients.
Rose plants live to feast on nutrients. Therefore, granular fertilizer should be applied every 2 to 3 weeks at the peak of the growing season.
When Is The Best Time To Fertilize Roses?
You should add the best rose fertilizers to the soil during the correct time for best results. The first fertilizer application should be during the middle or towards the end of spring. This is after the winters have ended.
Later, you need to start reapplication as the season progresses towards the autumn months with an interval of 2 to 3 weeks. Always stop fertilizing at least 6 to 8 weeks before the first snow or winter wave.
Doing so enables delicate shoots to become hardy. They will be able to survive the frost season and revive quickly later on.
Sunlight, Water, And pH Requirements For Rose Plants
Sunlight
Rose plants thrive well and are easier to care for than other flowering plants. Rose plants do not react to temperature changes very rapidly. They usually go into hibernation mode during the winters. Although hibernating plants look like a pile of sticks, they are not dead. These usually revive with lush green foliage and vibrant blooms once the growth season kicks in.
Rose plants require at least 5 to 6 hours of bright, direct sunlight to thrive well. Adequate sunlight promotes the abundance of flowers and blooming capacity.
If you have potted plants, make sure you place them near a window that lets in enough sunlight. Ensure that they receive shade during the afternoon as direct sunlight for more extended periods of time can burn the foliage.
Water requirements
Watering plants is an essential and integral step for maintaining healthy plants. Immature rose plants need to be drenched in water to help them thrive. Make sure you do not completely drown the roots, as this can lead to root rot. The Kintore content should be adequate but not overwhelming.
Mulch is also a great way to help the soil retain its moisture. Simply gather it around the plant base to rule out stress from external factors.
You will need to water your plants well during the summers. Make sure you water your rose plants at least two times each week. Water should always seep into the root area without drowning them. This will not only help improve water absorption it will also keep fungal diseases at bay. You can start watering less as the weather turns colder.
pH level
Rose plants thrive well in well-drained loamy soil. The soil should be wet but not flooded. Therefore, never opt for clay soil for your roses.
A pH level between 5.5 to 7.0 is ideal for rose plants. These plants do well in lower pH levels, and an acidic level of 6.5 will produce the best foliage and flowers.
Tips And Tricks For Rose Plant Fertilization
You could have the best rose fertilizer at hand, but you will not get great results if you ignore the tips below. These are tried and tested tricks used by most garden enthusiasts. Let’s take a look:
- Roses with bare roots should be placed in a dark and cold room. Make sure they receive enough moisture.
- Create a protective shield for your roses from the cold weather by keeping your plants near boundary walls and walkways. The walls will shield the plants from the cool air, but you need to make sure they get enough sunlight.
- Do not overcrowd your soil bed by planting rose plants very close to each other. Overcrowding usually results in powdery or downy mildew.
- Pack rose stems with loose soil once they have been transplanted to newer soil. This will help them adapt to their surrounding environment.
- Add banana peels or powder to the soil to enrich it with minerals like potassium, calcium, and magnesium. Make sure you place banana peels at least 4 to 6 inches deep into the soil. This is after you have soaked them for at least two weeks in water.
- Keep your petals and leaves dry when you water your plants. This will prevent the development of fungal diseases and infections.

FAQs
What is the best time to fertilize roses?
For immature plants, the soil should be prepped beforehand. The soil needs to be fertilized in early spring before new rose plants are transplanted into the soil. Once planted, you can make the first fertilizer application in mid or late spring. Make sure that winters have completely ended before doing this. Fertilizing right before or after the dedicated periods can end up damaging your plants.
As autumn starts nearing, you can start to fertilize once again in gaps of at least 2 to 3 weeks. All fertilization should be stopped entirely at least 6 to 7 weeks before the frost kicks in. This will enable your toots to get hardy.
What is a natural fertilizer for roses?
You can add many natural fertilizers to promote healthy soil for your rose plants. These include:
Banana peels are a source of magnesium, calcium, and potassium.
Epsom salts.
3 to 4-day old animal manure. Never use new manure as this can burn your plants.
Bone meal rich in phosphorus.
Dry blood meal rich in nitrogen.
Greensand rich in potassium.
Seaweed rich in nitrogen.
Rock phosphate-rich in calcium.
You can add some of these on their own while others can be mixed together for better results. However, it is essential to carefully determine what your plants lack and replenish the soil with those nutrients. Ensure you do not add too many nutrients, as excess will bring more harm than good. Your foliage may turn unhealthy and yellow.
Do roses like coffee grounds?
Rose plants love mulch and other organic matter. It is no surprise that they love to feed on coffee grounds as well. Organic matter is broken down by microbes and insects such as earthworks into less complex nutrients. The more superficial elements are easily absorbed by the plant roots. Organic matter is an excellent slow-release fertilizer.
To add coffee grounds to your soil, simply sprinkle the coffee powder around the rose plants. Rain and earthworms will help decompose and decay the coffee. If there is no rainy weather forecasted, you can go ahead and water the soil after application. You can also use coffee grounds on the soil before transplanting rose plants to boost acidity and lower pH.
Can I sprinkle Epsom salt around plants?
Epsom salts or magnesium sulfate are an excellent source of both magnesium and sulfur. Many gardeners religiously use Epsom salts for rose growth. Epsom salts result in greener and fuller foliage with abundant blooms that are beaming with color and scent. An ideal mix is a tablespoon of Epsom salt in a gallon of water. You can spray this solution directly onto the soil.
Alternatively, you could go ahead and follow an organic mix recipe if you prefer.
Prep your soil by watering your roses. Add a mixture of 110 grams of Epsom salt, 230 grams of fish meal, and 110 grams of bone meal. Sprinkle generously and follow with watering. This will allow the Epsom salts to dissolve and be readily available as a solution for absorption by the rose plant roots.
