For example, fertilizers are divided into organic and chemical products based on the components.

Organic feeds contain organic matter such as compost, manure, or natural deposits such as saltpeter.

Generally, people prefer natural over chemical fertilizers as they are more environmentally friendly. To be more specific, it nourishes the plants while enhancing the productivity of the soil at the same time.

Meanwhile, synthetic fertilizers can boost fruit yield easily and quickly. On the other hand, using inorganic feeds may lead to a mineral shortage in the soil.

Different types of fertilizer also come in different forms, including powder, granular, and liquid.

Powder Fertilizer

Powder fertilizers are useful for applying in large areas on farms or in orchards. People often spread them by hand before watering the trees to enhance absorption. 

Alternatively, these types of fertilizer can be diluted with water before being applied as a liquid fertilizer.

Using powder is an economical way to nourish your plants, but make sure you measure the ratio carefully. Otherwise, it could cause root burn.

Granular Fertilizer

Granules can be applied directly on top of the soil without watering. It is a slow-release option, which means it naturally decomposes to add nutrients to the soil.

Since granules are heavily concentrated, they can nourish your plants for a long time, even up to nine months.

If you use granules to fertilize your orchards, a seed spreader may come in handy.

Liquid Fertilizer

Liquid fertilizers for fruit trees are probably the easiest to apply in your garden. You only need to dilute them with water if needed, then use a hose to spray it over your plants. In that way, using liquids can save a lot of time and effort.

Of course, it is essential to follow the recommended measurements to avoid root burn.

What To Consider When Buying Fruit Tree Fertilizer

Nutrient Profile

Plants have different nutritional demands at different times. For example, young fruit trees need nitrogen, while mature ones need more minerals.

To be more specific, nitrogen is helpful in helping plants grow and develop. If a plant suffers from a lack of nitrogen while growing, it will slowly sprout and have low productivity.

Meanwhile, phosphorus plays an important role in root formation and blooming.

Last but not least, potassium facilitates the transportation of nutrients in the trees. It also helps to enhance fruit quality and the overall resilience against adverse conditions.


Pay attention to how you can apply fertilizer to fruit trees. Generally, there are two ways, including soil application and foliar feeding.

Soil application means you apply the fertilizer directly to the soil so that the roots can absorb the nutrients quickly. Meanwhile, foliar feeding refers to spraying the nutrients over the plants.

Foliar feeding means spraying fertilizers over the plants.

For fruit trees, soil application will be more effective since it is difficult to cover the whole tree by spraying.


You should choose a pack size that fits your needs. Buying a large pack will be more cost-effective if you have a large garden. For only one or two fruit trees, you can choose fertilizer spikes or capsules.


Safety is a concern if you are buying chemical fertilizers. Especially in case you have pets at home, you may want to opt for something pet-friendly.

When To Fertilize Fruit Trees

This section will provide a detailed guide on the right time to fertilize fruit trees.

Generally speaking, spring is the best time to feed fruit trees since they need enough nutrients to push out leaves and grow blossoms. Ideally, you should fertilize your plants one month prior to bud break.

Should you happen to miss this stage, you can always fertilize your plants anytime you want until June.

It is advised to stay away from feeding your plants with any nutrients in the fall. During that time, the trees do not need additional nutrients to grow.

If you insist on fertilizing them, you may encourage the growth of young branches and leaves, which may not withstand the upcoming cold winter.

The perfect time to feed your plants depends on many other factors, such as their ages, the condition of your soil, the place where you live, and more.

Let’s take a look at when to feed some specific trees.

Orange, Lime, and Lemon

These citrus species grow best in temperate climates, so it is ideal for feeding them in late winter, late spring, and late summer.


Apple will benefit from fertilizers applied in early spring, also known as the pre-flowering stage. Then, you should add more nutrients after the blossom season to encourage fruit growth.

You should fertilize apple trees in the early spring.


You can feed mango trees at the same time as citrus. Note that young mango trees need feeding once in mid-spring and again in the middle of summer.


Figs are easy-to-grow plants that do not need extra feeding. Therefore, you should only fertilize them if they grow slowly or have yellow leaves.


Fertilizing banana trees should be done in early spring to encourage foliage growth. When the trees start to blossom, you should feed them with extra potassium.


Like figs, cherries rarely ask for additional nutrients from fertilizers. However, you should fertilize these plants if you observe slow growth.

A rule of thumb is to fertilize mature cherry trees every two months and every four weeks with small potted plants.


Peaches are also a type of light feeder. If you have mature peach trees in your garden, you should fertilize them twice: once in early spring and again after the blossoms.

Tips For Fertilizing Fruit Trees

#1  Measure Their Annual Growth

You should measure the annual growth of your fruit trees to know whether they are growing well or not. 

Typically, a healthy fruit tree will grow about 18 to 24 inches in a season. If your trees are growing on target, there is no need to add fertilizers.

In case your plants fail to grow as you expect, you should feed them more nitrogen.

#2 Add A Reasonable Amount Of Nitrogen

Nitrogen helps promote growth and fruits, but too much of a good thing can be bad. In this case, adding too much nitrogen may harm, or even kill your trees due to nutrient deficiencies.

#3 Avoid Adding Nitrogen After June

Applying nitrogen-rich fertilizer in the fall can prevent the fruit trees from going into dormancy when winter comes. If you forget to fertilize your plants before June, it is better to add mulch and wait until spring.

#4 Mulch In The Early Spring

Mulching is highly recommended as it offers many benefits. More specifically, mulch enhances the productivity of the soil by increasing microbes and improving texture.

In addition, mulching also helps retain water and keep grass away from the drip zone of your fruit trees.
