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).
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.

Jobe’s Organics 09727 Berry Granular Plant Food 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
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
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.

Fertilizer for Blueberries Buying Guide
When growing blueberry plants, your ultimate goal is to have harvestable fruit at the end of the growing season. In order to achieve this, it is vital that you have good quality products on your side to help you out. Fertilizers are one of the most important additives you can access if you want to curate a larger, higher quality harvest. Let’s look a little closer at fertilization and how you can use it to your advantage in creating a massive, delicious berry harvest.
What Are the Best Types of Fertilizer for Blueberries?
It seems that when trying to grow blueberry plants http://www.ucanr.org/sites/nm/files/76767.pdf , you should opt for an ammonium form of nitrogen. This is because while blueberries respond well to the presence of nitrogen like most other fruit-bearing plants, substances that utilize the nitrate form of nitrogen tend to be toxic to blueberries. This means that while other berry plants enjoy nitrate formulations, blueberries may actually be outright killed by the presence of such a product. This means that these types of fertilizers are obviously not the best type of fertilizer forstrawberries.
To combat this, always opt for an ammonium fertilizer like urea, cottonseed meal, or ammonium sulfate. Furthermore, try to find one that is listed as a slow-release nitrogen source to prevent leaf-loss and other issues and support long-term growth and fruit production over short bursts of fertilized growth. This will help you a lot more as your plant matures and sets you up with good base health for fruit production. Fortunately, this means that many of the products you find will be an organic fertilizer for blueberries.
When Should You Fertilize Blueberry Plants?
Blueberries do well with varying fertilizer applications. Instead of one large dosage all at once, you should attempt to do three different treatments, spacing them out to help promote growth all season long. To do this, first, fertilize your plants at the beginning of the growing season to stimulate growth and leaf production. Around six weeks later, apply a second mid-season dosage to help it along as it begins to produce fruit. Your third and final application will come just before harvest to ensure the production ripens properly. With this method, your plants are supported through the entire season, allowing them to grow unhindered and flourish.
How Often Should You Fertilize Blueberry Plants?
Generally, fertilizing blueberries just during the growing season is enough. Over-fertilizing your plants can damage or kill them so it is best to err on the side of caution and avoid fertilizing them throughout the year.
During the growing season, you can either opt for a three-part support system fertilization method, a two-part beginning and end method that involves fertilizing at the beginning of the season and just before harvest, or a one and done approach where you fertilize at the beginning at leaving it be the rest of the season. Which will work best for you will depend on your area’s specific growing parameters and how your plants respond to the fertilizer you are using, meaning you may have to play around with it a bit to figure out what best suits your needs. This is especially true for those looking for a fertilizer for blueberries in pots, as they tend to have less access to natural nutrition that in-ground plants can tap.
Here are some of the best fertilizers you can grab online, chosen for their reviews, quality, and product specifications. Take a look and see which will best suit your crops and needs!
