Choosing the Right Fertilizer for Your Roses

Choosing your rose fertilizer is an important decision that could make or break the health of your roses. It is important to be selective and choose the right fertilizer for your climate, soil, and specific rose varieties. There are a few points to consider when selecting a fertilizer: type (organic or chemical), application method, and frequency of applications.

Organic fertilizers include fertilizers made from natural materials such as bone meal, blood meal, kelp meal or feather meal. Organic fertilizers provide a slow-acting release of nutrients into the soil that helps maintain good soil conditions over time. Additionally, organic fertilizers are helping to keep carbon in our soils thereby promoting healthy growing conditions and assisting with aerobic respiration which allows oxygen to penetrate deep into the root system.

Chemical or synthetic fertilizers are good choices when you need quick results with higher concentrations of nitrogen specifically tailored to roses’ needs. Chemical fertilizers tend to be more cost effective than their organic counterparts however they do not improve the long-term health of the soil. Additionally, many chemical products contain potentially toxic residues which can pollute groundwater if used in excess or inappropriately applied so careful use is imperative for plant health and our environment’s benefit as well.

Application methods and frequency vary depending on what type of fertilizer you’ve chosen. For organic products—such as bonemeal—it’s best applied before planting and worked into the top 6 inches of soil after worked into dormant beds in late winter/early spring prior to bloom season for existing beds (removing any weeds first). Chemical feeds should be applied every few weeks during blooming season following label instructions carefully for dosage amounts based on size/unit measurements suggested per intended usage area (square feet) along with correct application types (watering systems versus granules).

No matter what type you go with it is always best practice to test your soil before making any decisions as this will give you valuable information as to what nutrients need replenishing as well as pH levels which can further aid in better management of your rose garden oasis!

Stage of growth

A rose’s stage of growth will affect what type of fertilizer your roses need. Roses are categorized into four stages of growth – vegetative, bud, re-blooming, and dormant. Each of these stages requires different nutrients to ensure healthy blooms and lush foliage.

Vegetative: At the beginning of the growing season, newly-planted roses are in their “vegetative” stage. During this period, it is important to nourish the plants with a balanced fertilizer in order to promote healthy root formation and strong stems for future blooms. Choose a balanced fertilizer like an 8-8-8 or 10-10-10 with trace minerals that provide essential nutrients for roses during this period of development.

Bud: As the plant progresses from its vegetative stage into bud formation, it will need extra phosphorus to foster strong flowering buds throughout the season. A 5-10-5 or 7-9-5 rose food should be applied during this stage for maximum budding potential.

Re-blooming: When flowers begin to form on the plant’s stems, fertilize more heavily with a formula like 10-10 – 10 while feeding with patience and caution – too much nitrogen can promote excessive foliage growth as opposed to additional blooming activity. Once fully formed blossoms have dropped off their stems, treat them with a slightly lower strength fertilizer such as potassium sulfate at 6 percent nitrate nitrogen or 5–7–7 plus trace minerals.

Dormant: As fall approaches, reduce your fertilizing intervals until winter arrives when you should stop altogether — allowing your roses to conserve their energy until springtime when they can then benefit from another dose of nourishment tailored for each specific stage in its lifecycle from start to finish!

Choosing the right formulation

When choosing which fertilizer to use on your roses, it is important to consider the right formulation or blend of fertilizers as each blend has its NPK value. NPK stands for Nitrogen, Phosphorus and Potassium. Each of these elements has a vital role in nourishing your plants.

Nitrogen encourages new stem and leaf growth (represented by the first number in most fertilizer numbers) while phosphorus promotes bloom development (represented by the second number). Potassium helps build strong roots and increase resistance to disease (third number). All of these elements should work together for optimum plant health. The amounts of nitrogen, phosphorus and potassium found in any fertilizer will be stated on the product label as three numbers separated by hyphens, e.g. 10-5-5 or 15-30-15 which refer to percentage levels of each element contained in that particular fertilizer product.

It is also important to note that organic fertilizers are slower acting, but work continuously over time whereas water soluble synthetic forms are fast acting but their benefits don’t last long. Depending on climate conditions, one or the other may be preferred depending on what type of rose you have.

How to Apply Rose Fertilizer

Applying fertilizer correctly is a skill that will help you keep your roses healthy and blooming. Fertilizers come in both organic and artificial forms, and the type you choose will depend on personal preference, availability and cost. Either way, the technique for applying rose fertilizer is the same.

Before you begin fertilizing your roses, make sure to read the instructions on the product label for specific application rates, as rates can vary depending on product type, soil fertility levels and other factors. Once you have understood the amount of product that should be used in each area of your garden, it’s time to get to work!

Organic Fertilizers: Apply dry organic fertilizers, such as plant meal or bone meal, directly on top of your soil around the base of each flowering bush by evenly distributing it outwards in a circle extending a few inches beyond (but not up against) its outermost branches. Water lightly after application.

Synthetic Fertilizers: Pour dry synthetic fertilizers into an appropriate-sized plastic bucket and add enough water to cover it completely. Stir until all of the granules have dissolved into the solution before pouring it directly around each rose bush’s perimeter (not towards its stem!) Water lightly again after application if needed.

For liquid concentrates that come in containers with built-in applicator tubes or sprayers attached: simply press down firmly against each rosebush’s ground line perimeter before squeezing out a slow but steady stream of concentrate so that it covers as much soil surface area as possible Circle around its perimeter until you see a change in color from where concentrate has been applied—this indicates that permeation through roots is underway!

Timing of application

It is important to assess the strategic timing of fertilizer application in order to optimize your rose’s bloom performance. Different seasons tend to require different concentrations and forms of fertilizer, due to varying amounts of sunlight, temperature variation, and water availability. Applying fertilizer at times when your roses are dormant or during extreme heat or cold can be detrimental, as they do not need any nutrition during that time.

During winter periods when the weather is typically cooler and days become shorter in length, there is reduced amounts of sunlight which generally limit the growth of your roses. As a result, it’s usually recommended that less potent fertilizers such as blooming fertilizers be used than those applied during other seasons such as spring and summer.

Spring and summer often boast longer day lengths with plenty of sunshine that encourages healthy foliage along with flower production. During this season it’s best to use a balanced general-purpose rose food as this enhances good plant health as well as keeps blooms vibrant while aiding growth throughout the entire plant. Additionally, watering should increase in frequency with consecutive days being wetter than others during dry spells–don’t forget foliar fertilizer applications!

Lastly, fall requires special attention due to significant reduction in temperature weeks before the actual season changeover occurs. At this stage it pays off tremendously to apply a phosphorus-heavy fertilizer like a bloom booster near the end of this season for better root development for an eventual strong start into spring’s growth period.

Proper application techniques

The proper use of fertilizer by the gardener is essential for healthy rose plants and maximum flowering. Here are some tips on proper application techniques.

When applying granular fertilizer to roses, it is best to use a drop spreader or a broadcast spreader to apply the product evenly throughout the garden bed. Be sure to distribute the product at least 6 inches from the base of each plant and water in heavily after application.

For a liquid concentrate or foliar fertilizer, mix according to directions on label and apply at full strength with a sprayer or watering can directly onto foliage and stem tissue. Water in lightly afterwards. Liquid fertilizers should be applied every one to two weeks during active growing periods for optimum health and flowering potentials.

It is important not to “burn” your roses by over-fertilizing; if too much fertilizer is used, you may experience leaf discoloration, reduced flowering, and even plant death due to toxic levels of nitrogen in the plant’s system. To reduce this risk completely, replace one third of your regularly scheduled applications with organic matter such as compost tea or well-aged manures throughout the season. This will add crucial organic nutrients slowly into soil while maintaining excellent fertility levels at appropriate concentrations in topsoil around plants. Don’t forget that roses have shallow roots which may be easily damaged by over-application of fertilizers so always follow recommended rate applications stated on packaging carefully when making nutritional programs for your garden!

Dosage and frequency of application

The rate and frequency at which you fertilize your roses will vary depending on the type of fertilizer you’ve chosen and the growing conditions. Most fertilizers formulated for use with roses will have directions printed on the package.

Organic fertilizers such as compost or aged manure are typically applied once or twice in spring and spread over the entire growing bed in a thin, even layer. If a granular fertilizer is being used, it is usually applied in late winter/early spring and then again during summer growth season. It should be diluted with water, according to package instructions, then spread evenly around each bush without getting any closer than 6 inches from the canes. For liquid feedings, check for recommendations for this type of fertilizer; applying every two weeks—once in early spring and then again 6–8 weeks later–can bring about maximum blooms throughout summer season.

The use of foliar sprays (liquid fertilizer applied directly to leaves) is not recommended but can be used if recommended by an expert as an additional source of nourishment during times of especially vigorous growth or weak foliage.

Additional Tips for Nourishing Your Roses

Taking extra care of roses will help ensure that they reach their maximum potential in terms of health and blooming ability. Here are a few additional tips to consider when nourishing your roses:

  1. Use composted soil or composted manure around your rose bushes. Composted soil has beneficial nutrients and microorganisms which will keep soils well aerated. Composting also helps to retain moisture in the soil, which is essential for roses as it’s difficult for them to draw water from below the surface.
  2. Mulch can help conserve moisture and maintain even temperatures in the soil for the roses’ roots. Organic mulches can provide additional nutrients as they slowly decompose over time and improve the soils fertility.
  3. Use a slow-release fertilizer to add an additional layer of nutrients to promote strong growth and large blooms in your rose bushes over the course of several weeks or months depending on the product’s formulation rate.
  4. Always water deeply after applying fertilizer; this will help prevent fertilizer burn and ensure that it is able to reach its full potential when absorbed by your rose’s roots system!
  5. Prune away old stems, leaves, and flowers regularly throughout spring/summer/fall for healthy new buds that can reach their peak at season’s end!


Mulching can be one of the most beneficial tasks you can do for your roses. Mulch helps retain moisture, moderates the soil temperature, keeps weeds down and adds organic matter to the soil as it breaks down. The best types of mulch for roses are natural organic material, such as compost, leaf mold or well-aged animal manures.

For a quick fix and instant gratification, an organic mulch such as fine bark, peat moss or chopped leaves will get your rose beds looking beautiful quickly before other materials have time to break down. Avoid piling mulch directly against plant stems; try to keep at least an inch between stems and any mulching material. 2-4 inches is generally best.


Watering your roses is essential in order to ensure the health and vitality of your plants. Rose bushes are very susceptible to dehydration, especially during periods of hot weather or drought. It is important to water roses deeply and thoroughly but not too frequently. Deep watering produces strong, healthy roots that are better equipped to acquire nutrients from the soil, while over-watering weakens the roots and can lead to nutrient deficiencies.

An estimated 1-2 inches of water per week should be provided during periods of active growth. In addition, a well-timed application of mulch over the root zone will help conserve moisture and reduce plant stress from seasonal fluctuations in temperature. A frequent light sprinkling will not penetrate deeply enough into the soil for rose roots; good irrigation practices include providing slow deep soaking with either soaker hoses or sprinklers on a timer. Flower beds should be watered at least twice a week for about 20 minutes each time for best results.

Feeling the soil regularly is also important; if it feels dry 1 inch below the surface, it’s time to water again!


In conclusion, nourishing your roses is key to having beautiful blooms that can last for many years. With the proper preparation and care, you can ensure that your rose bushes remain healthy, spread more floral aroma throughout the garden, and have a long line of blooms to show off in your yard.

Consider adding compost or fertilizer to boost the nutrients in the soil. Proper watering techniques are also essential when taking care of rose bushes and making sure they receive enough water without too much or too little. Pruning is also crucial as it keeps plants healthy while allowing more space for new flowers to grow.

Finally, inspect your roses on a regular basis and take remedial action if necessary to keep pests and diseases at bay. With these tips in mind, you can achieve beautiful roses that surpass even those of an expert horticulturalist’s garden.
