  • NPK: 3-5-5
  • Type: granules
  • Use: every 2-3 months

More features: organic, fits for new trees, OMRI listed, contains Jobe’s Biozome

Jobe’s Organics 09224 Fruit & Citrus Fertilizer is a fast acting, OMRI-listed, organic product that is infused with Biozome, Jobe’s patented beneficial microorganisms, which is a blend of mycorrhizal fungi, archaea, and healthy bacteria. It also contains bone meal, feather meal, and processed manure. Altogether, the ingredients work to clean the soil and restore it to a balanced, healthy state, making this the best organic fertilizer for fruit trees at its price point.

Specifically, Archaea works by breaking down minerals and hydrocarbons into nutrients and trace elements that trees can readily absorb. Mycorrhizal expands the roots’ surface-absorbing area by 100-1000 times, thereby helping trees absorb more nutrients and water. Bone meal is rich in calcium and phosphorus, which promotes root strength, blooming, and fruit development. Feather meal, a rich source of nitrogen, promotes greener foliage and overall plant health. Processed manure contains high amounts of calcium, nitrogen, phosphorus, potassium, sulfur, and organic matter and greatly improves soil condition.

The fertilizer has an NPK ratio of 3-5-5 and should be applied every 2-3 months. You can use it during soil preparation, on seeds and new plantings, established shrubs, and mature trees. For soil preparation, use 1½ tablespoons for each 2-inch plant. For seeds and new plantings, use 1½ tablespoons per 4-inch pot. For established plants, add 1½ cup per foot of plant spread at the drip line. And for mature trees, add 3 cups per 1″ of trunk diameter at the drip line.

The slow-releasing EarthPods Premium Fruit & Citrus Plant Food is rich in plant nutrients, natural growth hormones, trace elements, and humic, fulvic and amino acids, among other beneficial soil microbes. Everything in this product is organic, from the fertilizer itself to the capsules in which it is enclosed and the packaging, including the ink used to print the container.

It’s specially formulated for dwarf fruit trees, and works by boosting overall plant health. This is also a great fertilizer for citrus trees. With an NPK formulation of 2-4-4, it stimulates root development and growth, blossoms, and improves leaf color. It also reduces transplant shock and builds resistance to pests, diseases, and other unfavorable conditions.

The product comes in a tube of 100 capsules, a number that can feed a single fruit tree for up to 4 years. If you have more trees, of course, it won’t last that long. Note that you can use it for both outdoor and indoor fruit trees.

Things to Consider

From the above descriptions and reviews, you can see just how different fruit tree fertilizers can be. In this next section, we’ll look deeper into these fertilizer variations vis-a-vis fruit tree types, and see which nutrients fruit trees need most and when you should fertilize the trees. We’ll also tell you which factors to consider before buying any fertilizer.

Which nutrients work best for fruit trees?

Any type of plant need special fertilizers – for example, there are fertilizers for tomatoes or fertilizers for palm trees. Fruit trees is not an exception.

During the early stages of growth, fruit trees require more nitrogen and less of the other basic nutrients. They need it for root growth and foliage development. That’s why a lot of the fruit tree fertilizers for new plantings and young trees have a high amount of nitrogen and less of the other macronutrients.

During bloom formation and fruit development, trees require more phosphorus to boost these functions. And so the best fertilizers to use during this phase are those with higher phosphorus content.

In all stages of growth, fruit trees continually need additional macro nutrients in smaller amounts and trace minerals too. The tree gets some of these from water, air, and organic matter as it decomposes around the tree. Fertilizer manufacturers also include these extra nutrients and beneficial microorganisms in their products to boost supply to the tree. When choosing a fertilizer, consider whether it has additional nutrients and in what quantity. Jobe’s Organics 09224 Fruit & Citrus Fertilizer, EarthPods Premium Fruit & Citrus Plant Food, and Dr. Earth Natural Wonder Fruit Tree Fertilizer are all examples of fertilizers with a diverse variety of macro and micronutrients.

5 Amazing Fertilizers for Fruit Trees to Grow the Juiciest FruitsWhen to fertilize fruit trees?

Fruit trees respond best when fertilized during or just before the growing season, usually from early spring to mid-summer. This is when buds begin to form and eventually break into flowers.

To prepare for the budding season in earnest, you can fertilize your trees up to a month before buds begin to form.

Avoid fertilizing the trees in the fall or winter because deciduous fruit trees are slowing down their growth processes at this time and don’t really need feeding.


Fertilizer prices range from $10 to $30+. When gauging whether the price is fair or not, you must measure it against the quantity of fertilizer being offered. $30 for a tin of 100 capsules, for instance, may be considered expensive, given that you may only fertilize a maximum of 5 plants per season. On the other hand, a 15-pound tin of granular fertilizer costing the same amount will be considered fair because you can use it for longer and on more plants.

Features to consider while buying the best fertilizer for fruit trees

Let’s now look at the specific features you need to consider before buying any fertilizer for fruit trees.

Fruit tree type

Some fertilizers may be suitable for specific fruit trees and not others. Different fruit trees may also require different amounts of nutrients, in which case the manufacturer will indicate how much product to use for each fruit type. In Down to Earth Organic Fruit Tree Fertilizer, for example, the manufacturer advises you to use a lower quantity of the product for pome fruits than what you’d use for stone fruits and other types of fruits.

Additionally, the fertilizer may be suitable for trees in all their different growth phases or it may be developed for use with either new plantings or mature trees only. For instance, Down to Earth Organic Fruit Tree Fertilizer is for established fruit trees only.

5 Amazing Fertilizers for Fruit Trees to Grow the Juiciest FruitsNPK

The NPK value refers to how much nitrogen, phosphorus, and potassium the fertilizer contains. It’s indicated in percentage and denoted by three numbers separated by dashes and is typically printed clearly on the fertilizer package. These three are the essential nutrients required by plants for healthy growth, and different products add them in varying quantities. Do a soil test to determine which nutrients your trees need most, and then buy the fertilizer that meets this need.

Pack size

Choose a pack size that corresponds to your requirements. If you have lots of trees, you’ll get more value in a large pack, like the 16-pound Jobe’s Organics 09224 Fruit & Citrus Fertilizer. If you only have one or two trees, a smaller pack will suffice. You can also choose spikes and capsules like EarthPods Premium Fruit & Citrus Plant Food or Miracle-Gro 4852012 Fruit & Citrus Plant Food Spikes. These would be expensive for someone with a big orchard.

Fertilizer form

Fertilizer comes in different forms, from powder and granular to liquid, capsules, and spikes. Liquid and powder forms are water-soluble and should be dissolved in water before application.

Granular fertilizers are equally water-soluble, but instead of dissolving them in water, you mix them into the soil, and then water the tree.

In spikes and capsules, the fertilizer is enclosed in a shell, which you then insert into the soil. Follow through with watering as usual.

5 Amazing Fertilizers for Fruit Trees to Grow the Juiciest FruitsEffectiveness

You can tell how effective the product is by how the tree responds to the fertilizer following application. Fertilizers should enhance root growth, make the tree more robust, enhance foliage by making the leaves bigger, healthier, and greener, and encourage bud-formation and blooming. A single fertilizer may not do all the above, but it should offer one or two benefits. Figure out what improvements you’d like to see in your trees, and then look for a fertilizer that offers them. Manufacturers specify the benefits on the package, so you’ll know what to expect from the product.

Easy use

The best fertilizers are easy to use, meaning they do not require tedious measuring and mixing. For those that need to be mixed with water, they should be fast dissolving without forming lumps. They should also be packaged in such a way that they’re easy to pour or come in pre-measured bits, as in capsules and spikes.

Tree care

If possible, pick a fertilizer that enhances the health and appearance of the trees, without just focusing on soil health only. Lots of fertilizers have visible plant care benefits, including insect and disease control, and boosting drought resistance. A good example is Jobe’s Organics 09224 Fruit & Citrus Fertilizer. Others, such as EarthPods Premium Fruit & Citrus Plant Food and Miracle-Gro 4852012 Fruit & Citrus Plant Food Spikes, will visibly change the leaves so that they’re noticeably bigger, plumper and richer in color.

Fruit tree growing tips and tricks

Choose fruit trees to grow based on your location. If you live in a cold region, go for fruit trees with high cold-hardiness so they can withstand the cold weather better. If living in warmer climates, choose fruit trees that are heat and drought tolerant.

Understand the environmental factors in your location and how they affect different trees. Then use this insight to choose your trees more carefully or find solutions to counter the effects if possible, for example, implement disease and pest control measures.

Embrace mulching to help retain moisture, which is crucial to healthy growth, especially in young trees. Mulching also slows down the growth of trees, thereby preventing premature flowering and allowing the tree to grow stronger and healthier, which leads to better blooming and fruit formation.

Prune your trees regularly to boost air flow, which in turn enhances plant health and growth.


This depends on a number of things, notably what nutrients are missing in the soil, the age of the tree, and where the tree is planted. The manufacturer indicates how much fertilizer you should add for each situation. In nitrogen, for example, this adds up to 0.125 lbs. of actual nitrogen (not formulated fertilizer) for year-old trees, 0.25 lbs. in 2-year-old trees, and 1 lb. for mature trees (8+ years).  Don’t exceed the recommended amounts as this will lead to over fertilization and may damage the tree.

It is not advisable to do so, since each fertilizer is formulated to respond a certain way when mixed into the soil or sprayed on leaves and to break down in a specific way to provide specific nutrients. Mixing fertilizers will mess up with the composition and can make some of the nutrients unavailable for absorption, or worse, damage the tree. If you want to use a different fertilizer, wait until the fertilizer you’d applied before is completely used up before introducing a new one into the soil.

Yes, largely because it is natural and contains plenty of beneficial nutrients and microbes. But these nutrients are less concentrated and may not be sufficient to meet the trees’ needs. You may use it in combination with fertilizer, which offers more than just nutrients. In addition to providing fruit trees with a higher concentration of nutrients and improving soil conditions, fertilizer also helps with insect and disease control, and improves drought conditions, all of which can negatively affect plant health.
