The best fertilizers for raspberries contain a high level of nitrogen (N). You can use a balanced fertilizer of eg. NPK 10-10-10. 0.8 ounces of nitrogen (N) should be applied per 10 feet row of raspberries when flowering in the first and second year. After year 3, twice the amount can b applied. The soil pH for raspberries should be pH- 6.0-6.5.

- Miracle-Gro Performance Organics Edibles Plant Nutrition Granules

Best Fertilizers for Raspberries
The Maryland University states that the right mulching and watering are essential for a plentiful raspberry harvest.
The amount of nitrogen (N) added to fertilize raspberry plants per year should be up to 3 ounces per 10 feet according to the Oregon State University.
This will vary on the type of raspberry.
Summer-bearing red and yellow raspberries will need slightly less fertilizer (2-3 ounces) whereas everbearing raspberries will develop best using 3 ounces of nitrogen (N) a year.
About Raspberries
The name ‘raspberry’ originates from the historic French raspise; the term in literal meaning refers to ‘sweet rose-colored wine.’
Very few people are aware of the fact that raspberries are not just one fruit but many combined in the form of a scrumptious blood-red delight.
It is made up of several tiny bead-like fruits known as ‘drupelets’ that are all clustered around a central core.
Each drupelet carries one seed, and thus, a raspberry contains approximately 100 to 120 seeds.
The raspberry is a type of aggregate fruit which normally has flowers with multiple ovaries.
All ovaries produce drupelets which can further be grown into a separate fruit.
Therefore, even if you think you have just one raspberry, the truth is you are holding at least a hundred.
Growing and caring for plants is an art that many excel at. Knowing the ideal conditions and type of feed your plant requires is imperative for its healthy development.
Similarly, raspberries may seem tricky to grow; however, once you understand the art, it is a joy to grow this wonderful fruit.
Raspberries can be eaten as plain fruit, pies, jams, crumbles, and more.
Having a vibrant and fresh bowl full of this colorful fruit is a beautiful sight for sore eyes.
What enhances your eating experience is eating raspberries that are freshly picked from your very own garden.

Although it is on the pricey side, it features more than what you can imagine.
This fertilizer should ideally be applied twice a year as it is a slow-release formula.
It gradually allows all its nutrients to sink into the soil, giving the plant and its root plenty of time to soak in all micro and macro components effectively.

In addition, the ingredients are blended in an acidic formula which is highly advantageous for the raspberry as well as other plants in general.
An acidic soil helps the plant take up minerals efficiently from the soil and simultaneously minimizes the probability of infection and disease.
Normally, raspberry plants prefer soils with a pH of 5.0 to 6.5 (mildly acidic); this level helps them grow better and produce nutritious fruits profusely.
This fertilizer does both these jobs; it adds nutrients into the soil and maintains an acidic environment throughout the growing season.
It is recommended to get your soil tested before buying this product as it works best in neutral to alkaline soils only.
If used in grounds that are already acidic, this fertilizer may lower the pH further, leading to various complications.

For alkaline soils and inexperienced gardeners, it is one of the best options in the market.
The most important nutrient for Raspberry fertilization is nitrogen (N)
Southern Ag All Purpose Granular Fertilizer
The Southern Ag All Purpose Granular fertilizer has a slightly different formula from the other feeds on this list.
However, its advantages outweigh its disadvantages; therefore, it is still among the top 5 fertilizers for raspberry plants.
Instead of the normal berry-specific formula, which is higher in the main three elements (NPK), this fertilizer has greater quantities of trace nutrients, including Calcium and Magnesium.
While this can be a little problematic for soils with low Nitrogen, Phosphorous, and Potassium, this is beneficial for grounds that have very low levels of trace elements.
The Southern Ag All Purpose Granular is also known as a general fertilizer due to its excellent formula. It offers an equal ratio of 10-10-10 (NPK), which is the highest balance among all feeds discussed in this list.
This product is an agricultural fertilizer designed to give similar results, regardless of the type and species of the berry plant.
The higher content of the main elements aids in growth, blooming, and fruiting, while the trace minerals help complete the relatively smaller requirements, such as characteristic color and smell.
It is a good option if your soil lacks the usual minerals or is in poor condition due to any cause. Furthermore, it works well for gardeners who dislike using different fertilizers for different berry types.
Its single application lasts for months, so you do not need to add it to your plants repeatedly.
Likewise, when using this, using soil-boosters or compost regularly is not needed.
Although highly beneficial, the Southern Ag All Purpose Granular fertilizer needs to be used carefully because of its potent formula.
If added in surplus, it can lead to other complications and toxicity. Therefore, please ensure that you use the required amount only.
Pros
- Balanced fertilizer with a general formula
- Highest nitrogen content
- Well-rounded and safe composition
- Great for soils with low main and trace elements content
- Works well even as a standalone fertilizer
- Provides relief from using composts or soil-boosters repeatedly

- If added excessively, it may burn the raspberry plants and cause more problems
- Careful handling

Best Fertilizers for Raspberries Buying Guide
Plants are almost as sensitive to environmental changes as humans.
Therefore, selecting the right fertilizer that completes all their requirements is necessary.
The raspberry plant usually does not give much trouble to its grower; however, it begins showing various signs of abnormality and disease if it is put in unfavorable conditions for a long time.
The growing pattern and fruit characteristics are primarily dependent on the fertilizer the raspberry plant is given.
While the NPK ratio holds immense importance, some other factors also play great roles.
Element Ratio
All elements are important for the raspberry plant; however, Nitrogen holds the greatest significance among all due to its crucial role.
It is involved in healthy and nutritious fruiting and encourages growth while maintaining the plant’s immunity. Therefore, looking for a fertilizer with a high Nitrogen content is essential.
Normally, berries take up a significant amount of Nitrogen as they carry a great number of seeds within them. It also uses other ‘big’ elements, such as Potassium and Phosphate that perform other functions while the berry matures.
Potassium is important for a raspberry plant as it enhances the taste and nutritional count, and it also gives the fruit its characteristic color.
Therefore, get your hands on a fertilizer that offers good amounts of these three elements; Nitrogen, Phosphorous, and Potassium.
Cost
While providing their plant the best of everything is the dream of every gardener, considering the price and cost is also crucial.
Before getting any fertilizer, please make sure that it contains all that your plant needs and is also within your budget.
Your raspberry plant may get used to one type of fertilizer only, which will require you to purchase it repeatedly. Thus, it is advised that you buy a fertilizer that is not too heavy on the pocket.
Pesticides
Several gardeners constantly worry for their plants thinking if they are strong enough to fight off infections and diseases.
Fortunately, the raspberry plant is fairly resistant to mild infectious bacteria and mostly does not require chemical assistance.
However, keeping a close eye on your raspberry plants is a good way to protect them from significant damage. Insects, such as aphids, thoroughly enjoy feeding on fruiting plant varieties.
To prevent an attack, you can get a fertilizer that strengthens the raspberry plant’s defense system so that it can limit the adverse effects till you spot the issue.
Similarly, you can get some ladybugs or praying mantis from a local garden nursery for keeping pests and insects at bay.
Additionally, please ensure that your plant does not spread the infection to other plants as controlling such a situation is often troublesome.
I also suggest checking your plant’s leaves’ undersides often to spot aphids and other insects before they can make things worse.
