There are few things more rewarding than growing your own food. Domestic plant growth gives an overwhelming sense of satisfaction while providing some of the healthiest food options you could potentially access. From classic garden foods like tomatoes and green beans to more interesting things like dragonfruit and avocado plants, it seems that more and more people are exploring their options with growing produce and herbs. One very popular option in recent years has to be blueberries (https://en.wikipedia.org/wiki/Blueberry).
A favorite in smoothies, salads, and just as a quick, simple snack, blueberries are high in antioxidants and are classified as a superfood due to their nutritional impact. They are also rather easy to grow, especially if you have good soil and a quality fertilizer on hand. A fertilizer is a substance that is added to the soil to increase the fertility and growth rate of things planted there. It can be either a chemical commercial product like Miracle-Gro or something simple like crushed eggshells, depending on your desired growth and plant types. Let’s learn a little about fertilizers and discuss some of the best fertilizer for blueberries.
In a nutshell, fertilizers are additive compounds you can place in the soil to either increase the fertility (link) of the area for your crops or replace nutrients taken by previous crop cycles. Fertilizers can be organic or chemically derived and can be a massive beneficial factor in the growth rate and fruit production of most plants, including blueberries. Let’s talk about a few different types of fertilizers and what benefits they potentially pose.
#1 Fertilizer for Blueberries
Created by Jobe’s Organics to service berry plants specifically by targeting their unique needs, this plant food style fertilizer rapidly breaks down the nutrients in the soil while providing a good system for nutrient absorption within the root system, improving growth and fruit production in the process. This OMRI registered product is suitable for all berry types, including blueberries of all subspecies. Environmentally friendly and safe for pets and humans, this product will not burn the fragile roots of the plant when applied as directed and is designed for easy use in most soil environments for your convenience.
While specifically formulated for seedlings and younger plants, this product is also reported to work well as a general fertilizer for upkeep and maintenance. The ingredients include organic, natural matters like feather meal, bone meal, composted poultry manure, sulfate of potash and various bacteria, endomycorrhizal, ectomycorrhizae, and archaea to help promote overall plant health and fruit production, making it a good fit for most plants of all ages.
Some reviewers do report that the dosage instructions on the packaging are a bit too light for their likings, with one even citing the brand’s customer service representative as stating a stronger dose than the one listed, so be sure to contact customer service if you have any concerns about your dosage strength. It is better to under-fertilize your plants than over, as over-fertilization can result in the roots becoming burned and damaged, which can stunt or even kill the plant and greatly reduce its ability to produce fruit in the long and short-term.
Ammonium Nitrogen Fertilizer for Blueberries
Ammonium Nitrogen fertilizer products contain varying levels of ammonia-based compounds, including ammonium bicarbonate, ammonium sulfate, ammonium chloride, and so on. These compounds are easily absorbed into the soil, making it good for plants in the initial growing period and for ongoing maintenance and care.
Please keep in mind that this is not the same ammonia you get from your local department store for cleaning purposes. Ammonia in that form is too volatile and corrosive and can kill your plants. These ammonia compounds have been neutralized in an alkaline solution to only provide the beneficial aspects of the solution, such as boosting production, leaf growth, and nitrogen presence within the soil.
Nitrate Nitrogen Fertilizer for Blueberries
Including compounds such as sodium nitrate, calcium nitrate, and ammonium nitrate, these types of fertilizers work to promote nutrient absorption and enhance organic anion. Vegetables generally take to this type of fertilizer more so than fruits, as do crops like tobacco. This means that while not all plants need a nitrate nitrogen-based fertilizer, some will benefit greatly.
There are, of course, additional types, including phosphorus, that we will touch on more in the rest of this article.
Organic Fertilizers for Blueberries
These are things that are based from organic materials like animal manure, worm castings, agricultural waste, industrial waste, and municipal sludge. These are things that utilize the nutrients in a biological matter to enhance the growth of plants; they are commonly used in organic food growth since they do not contain laboratory modified chemical blends and use natural chemical alternatives.

Certified with the Organic Materials Review Institute, this formula is curated using primary and secondary plant nourishing materials, including calcium, zinc, sulfur, and iron. This allows it to supply a good amount of nitrogen, phosphorous, and potassium directly to the plant’s root system and ensure a good delivery of other secondary nutrients within the soil’s chemical makeup. The proper rationing of these minerals assists in creating healthy greenery, fragrant blossoms and blooms, and a large amount of fruit production. The brand also notes that this product can be used to feed other fruit trees and plants, as well, to assist in production and growth aside from just that of berries. The recipe for this product includes a host of popular and powerful ingredients like fish bone meal, feather meal, greensand, alfalfa meal, basalt, langbeinite, kelp meal, zinc sulfate, and sulfate of potash.
