11 Best Fruit Tree Fertilizers + When To Fertilize Fruit Trees

One bite of a sun-ripened piece of fruit and you’ve got the flavor of summer itself, right in the palm of your hand. Growing fruit trees gives you an even grander seasonal experience plus access to some healthy snacks at the peak of freshness.

But, like all living things, fruit trees need a healthy environment to thrive in and, oftentimes, a little extra boost of nourishment to help them generate all that juicy fruit. Fruit tree fertilizers can provide just the nutrients needed to do just that. Let’s take a look at the different types available.

Types Of Fruit Tree Fertilizer

You’ll notice from our selection of best fruit tree fertilizers that we have focused our top eleven picks exclusively on natural and organic fertilizers. The reason for this is simple, fruit trees respond really well to soil environments that have been nourished with organic matter. But, let’s face it, eating the fruits of our labor that have been fertilized with all-natural ingredients rather than any synthetic chemicals is better for us too, right?

For the most part, these organic fertilizers come in three main varieties:

Fruit Tree Fertilizer Spikes

Slow-release spikes are one of the easiest to use, especially if you have more than one fruit tree. Pre-measured and compact for easy storage, they carry far less risk of run-off and root burn.

Watering them in is not necessary either, as nutrients are released by micro-organisms that naturally live in the soil. This method of application also carries the added benefit of stimulating an increased resistance to tree disease and pests.

Granular Fertilizer

Granules are another slow-release choice. Heavily concentrated, they provide consistent nourishment for up to nine months. No watering is needed to activate and is less likely to leach into nearby surface or groundwater.

Apply them by simply sprinkling them around the base of your tree or work them into the soil for faster feeding. For larger, orchard applications, a seed spreader can be used for a lighter workload.

Powdered Fertilizer

Powder fertilizers can be applied either directly into the soil around your tree’s base or diluted in water as a “tea”. This type is perfect for larger applications such as in orchards or on farms but does require a bit more effort in smaller spaces. While these are some of the most economical, they do carry a risk of root burn if exact measurements are not used.

Liquid Fertilizer

Liquids can conserve water and time, especially if you choose one versatile enough to use when watering the rest of your garden. Nutrients are carried to the root system through the soil where the biggest benefit is the speed at which nutrients reach the roots. Liquid feeds also tend to keep the pH levels in your soil balanced. However, too much of a good thing can cause over-feeding and may lead to root burn so always follow the manufacturer’s guidelines and measurements.

Organic Fruit Tree Fertilizer Vs Synthetic

Choosing an organic or synthetic (inorganic) fertilizer is a matter of preference and end goals. A basic understanding of the difference can help you make a solid fertilizer choice.

Organics are plant or animal-based containing manures and other natural materials. Inorganics are manufactured with minerals and synthetic chemicals. Organic feeds contain lower nutrient levels but can nourish fruit trees for longer periods of time while also improving the soil. Using inorganic fertilizers can result in a higher yield of larger fruits. However, they can also potentially contaminate nearby water sources.

Fruit Tree Food N-P-K Ratio

Fruit trees are far more successful when they have access to the right combination of macronutrients. These are nitrogen (N) – for healthy branches and leaves, phosphorus (P) – for a robust root system and an abundance of blooms, and potassium (K) – for durable resistance to disease and pests.

When you are choosing the right fruit tree fertilizers for your needs consider: Is the surrounding soil in need of amending? Do you have an orchard of trees or a single feature tree in your garden? Are feature trees in the ground or in a pot? The answers to these will determine if you need higher nitrogen content or perhaps a bit more phosphorus or potassium.

So, what exactly is NPK?

Every fertilizer label will display three numbers (X-X-X). These numbers are known as the N-P-K ratio of that fertilizer, indicating the proportions of nitrogen, phosphorus, and potassium in it. For example: A 6-2-3 NPK contains 6% nitrogen, 2% phosphorus and 3% potassium. Every plant and tree requires these three elements in order to thrive, just in different proportions, or NPK ratios.

Each type of fruit and nut tree has its own N-P-K needs in order to produce lush foliage and healthy, flavorful fruits. When considering what NPK balance to purchase, certain environmental conditions should also be taken into account.

However, we realize it’s probably not practical to have a specific fertilizer for every tree in your garden, right? So our list of fertilizers is selected with convenience in mind and they make a great all-around option when you just want to buy one fruit tree fertilizer for home use.

11 Best Fertilizer For Fruit Trees Reviews

Through personal trial and error and experience of growing fruit trees over the years, I know that no single fertilizing formula is perfect for every situation. Not to mention we all have our own personal preferences when it comes to gardening. Some folk prefer an all-purpose product that can be used for a variety of garden feeding requirements. Other people will need a very specific product for a single purpose, such as for an ailing fruit tree or to increase yield. With this in mind, my pick is based on a broad selection of excellent products for you to use when fertilizing your fruit trees at home.

I’ve looked at the quality of the fertilizer ingredients, its overall performance as well as the level of customer satisfaction taken from thousands of customer reviews across all major retail platforms, and of course the product’s ease of use.

When To Fertilize Fruit Trees

Now that we’ve covered some of the best options for fruit tree fertilizers, let’s talk about when to fertilize. Yes, each product label comes with basic instructions, which is great. But, these products cover a broad range of fruit-bearing trees. And, there are a few important points to consider for specific types of fruit.

For example, what gardening zone is your garden or orchard? Feeding times may need to be adjusted according to when spring and fall begin. How old is your tree? Younger trees typically follow a different fertilizing schedule which then changes once they reach fruit-bearing age. What is the condition of your soil? Sandy, higher clay content? Is the pH balance right for the type of fruit tree you have? Is it lacking in either nitrogen, phosphorus, or potassium? You’ll want to do a soil test using a soil pH test kit BEFORE fertilizing so you know exactly how to amend the soil for a healthy, thriving tree if needed.

If you happen to live in the southern hemisphere, you too can benefit from these recommendations, simply disregarding the referenced months. After making the necessary adjustments to your soil, you’re ready to give your fruiting beauties the individual attention they need.

When To Fertilize Apple Trees

Apples benefit most from three feedings. First, in early spring (pre-flowering), the second, just after flowering (to encourage thorough fruit formation), and ONLY IF NEEDED, a third to bolster foliage growth. Too much nitrogen will inhibit any growth of new foliage during the summer months.

When To Fertilize Peach Trees

Unless your soil needs amending, peaches need no fertilizing until they reach fruit-bearing age. For established trees, two feedings will suffice. Once in early spring before flowering and again just after will give your peach trees the feed they need for vibrant leaves and juicy fruit.

When To Fertilize Fig Trees

Ground-planted figs are slow-growers and are very easy to care for, rarely requiring extra feeding. Fertilize them only if you observe slow growth or yellowing leaves. However, in containers, with no other access to nutrients, you’ll need to feed and water them once a week.

When To Fertilize Orange, Lemon And Lime Trees

Citrus benefits from three good feedings per growing season. Because they typically grow in more temperate climates, the first feeding should be in winter (around February). The second, in late spring (after flowering) with the final dose being applied in late summer.

When To Fertilize Mango Trees

Well-established mangoes only need feeding once each spring, summer, and fall. New plantings require only two, once in mid-spring and again in midsummer until they reach fruit-bearing age. If you grow citrus trees, you can actually feed mangoes and citrus on the same schedule.

When To Fertilize Cherry Trees

Like figs, cherries are light feeders that don’t really need extra help. But if the soil doesn’t provide what they need or if the tree is failing, the general consensus is: for potted trees, every 4-6 weeks and every 2-3 months for larger, mature trees.

When to Fertilize Banana Trees

Fertilizing banana trees should start early spring, as this plant is as much about its foliage as its fruit in most countries. So I would recommend a switch from nitrogen-rich to potassium-rich banana tree fertilizer as soon as the flowers begin to appear.

Fertilizing Fruit Trees In Containers

Of course, having an orchard full of fruit trees is every homesteader’s dream. But, what if you live in an urban setting. Maybe in a townhouse with a small yard or even an apartment with only a tiny, little balcony? Are you out of luck? Absolutely not! Dwarf fruit trees were cultivated for just this type of living, giving urban dwellers the experience of growing their own healthy snacks and breathing in all that amazing fruit-blossom fragrance.

Even in a small outdoor space, you can easily grow a fruit tree or two in some large, decorative pots. But, unlike trees grown in the ground, they need a bit more attention. The frequent watering needed will inevitably result in soil and nutrient run-off as the excess water drains. So, more frequent feeding will also be necessary.

As we’ve seen, many fruit tree fertilizers have higher levels of nitrogen. This is really beneficial for full-sized fruit and nut trees. In containers though, the excess nitrogen will focus more of the tree’s energy on producing new leaves and less on producing flowers and fruit. So, when choosing a fertilizer for potted trees, be mindful of that first number in the NPK ratio. It should be equal to or lesser than the other two.

Unless….you have dwarf citrus or avocado trees. In contrast to other types, these depend on generous amounts of nitrogen to produce all that lovely fruit. So, that first NPK number will need to be higher.

Fertilizing Fruit Tree In The Ground

Compared to potted ones, established fruit trees growing in garden beds or orchards, have some different needs. Simply due to the larger and more diverse environment, they grow in. The best advice? Get to know your trees. Understanding their specific needs means your fruits will meet and maybe even exceed your expectations, season after season.

One way to get chummy is to simply observe them. When do the first leaves appear? When do they flower and start to bear fruit? When you’ve established the timing of these events, you’ll know exactly when to fertilize them.

Depending on the type of fruit you’re growing, you may need to feed them two or three times per growing season (label instructions may suggest differently, depending on the application type, and that’s fine). Typically, this would start in early spring, just before flowering. This is when the trees begin their growing cycle and absorb the most nutrients.

If you live in a more temperate climate, you can apply the first dose as early as February, but not before. A second time, after flowering and before the fruit starts to appear. Then a third time, only if needed, in the fall. If fertilized too late, new growth on certain fruiting trees will be susceptible to frost damage which can extend to other parts of the tree.

So again, when you know what to look for, your garden-planted fruit trees will be happy to tell you what they need and when.
