I’ve been growing fruit-bearing trees for some years now and you can believe me when I say that relying just on an appropriate amount of sunlight, good soil, and sufficient water isn’t enough to get the best out of them. I also know a thing or two about choosing and using the best fertilizer for apple and pear trees, so read on to find out more.

Choosing the Best Fertilizer for Apple Trees

There are hundreds of different fertilizers on the market, but apple and pear trees need a specific balance of nutrients and you’ll want to look out for both during the planting and growing stages of an apple and pear tree’s life. These three primary nutrients are common to all fertilizers and they are nitrogen, phosphorus, and potassium. 

Nitrogen is essential in aiding new growth and is of particular importance to the successful growth of pears and eating apples. Phosphorus helps build sturdy roots, and potassium will keep the plant cells healthy and perhaps most importantly, is what encourages the development of new buds and fruits.  

When you don’t provide your apple trees with these three nutrients, it can cause stunted growth, pests to accumulate on the tree, and the potential for diseases. While fruit trees and other plants can obtain these nutrients from the soil you’ve planted them in, there are numerous reasons why they won’t be getting them in the right quantities. This includes depleted soi and overbearing or hungry roots from neighboring trees or plants,  

The best way to determine what, if any, nutrients your apple tree is lacking is to test the soil’s pH using a soil test kit. From there, you can start searching for the best fertilizer. You’ll want one that provides the nutrients they need but you’ll also want a fertilizer that compliments your gardening style. Here are some options for you to consider.

Granular Vs. Liquid Fertilizer

Granular fertilizers are tiny particles that are designed to release slowly over time. Once you incorporate a granular fertilizer into the soil around your apple or pear tree, it will continue to nourish the soil and fertilize the roots every time you water them.  

Liquid fertilizers are fast-acting and offer a quick burst of nutrients to your fruit trees once they have been absorbed by the roots of the tree. They are more prone to be washed away and need to be used more frequently. The flipside of liquid fertilizers is they tend to be a more concentrated formula which can lead to fertilizer burn or when used frequently, can lead to over-fertilizing.

Liquid fertilizers work in two ways. You’ll either need to dilute the concentrated formula with water before applying it to the base of your apple or pear trees. This needs to be done regularly during the growing season. Alternatively, liquid fertilizers can be used as a foliar feed, which can be sprayed onto the foliage of fruit trees. More about that in a minute.

Liquid Concentrate or Spray

If you’re looking into liquid fertilizer, you’ll need to decide between liquid concentrate or spray. You won’t want to use these products on newly planted trees, but they’re a great option later down the line. Liquid concentrate is easy to apply by pouring the appropriate amount into the soil of your tree. 

Spraying liquid fertilizer is perfect for correcting deficiencies and is referred to as foliar feeding. This type of feeding is when you spray liquid fertilizer on the plants, and they absorb the nutrients through their foliage. 

Fertilizer Granules or Powder

Granules, also known as pellets, and powder are another popular fertilizer for plants. Using granules or powder is ideal for newly planted apple or pear trees. When it comes to these types of fertilizer, powder fertilizers are just powdered versions of the same granule fertilizer. 

When using powder fertilizer, you can use it in either form by applying it to the soil directly or diluting it in water first. While granular fertilizer, in general, is slower release, the powder version is generally faster than using granules. 

Fruit Tree Fertilizer Spikes

Fruit tree fertilizer spikes quite simply fertilizer that has been formed into a stake, where the pointy end gets hammered or driven into the ground. They’re easy to install in rows beneath fruit trees and help deliver fertilizer in a precise manner that encourages even distribution in the soil.

Fertilizer spikes offer a mess-free approach because they are pre-measured and simply get buried below the surface of the soil. No mixing or digging and no odor for your dog or cat to get excited about. They work on a slow-release basis, dispursing nutrients gradually, and can last for up to eight weeks.

Organic Apple Tree Fertilizer

Most organic fertilizers are high in natural nitrogen sources, which many fruit trees crave. Some great examples of ingredients to look for in your organic fertilizer include soybean meal, composted chicken manure, blood meal, and other composted manure.

Organic fertilizers are the safer option if you are planning on eating the harvested fruit because they don’t contain any chemical-based substances that could be potentially harmful if ingested.

Moreover, they are safe for humans, animals, and the environment. That is because they consist of naturally occurring materials found on farms and in nature.

Pear and Apple Tree Fertilizer N-P-K 

Regardless of what type of fertilizer you choose, you’ll want to make sure there’s an appropriate amount of N-P-K in the formula. This includes the three main macronutrients all plants need to thrive, nitrogen, phosphorus, and potassium. 

Nitrogen (N) is what makes plants grow bigger and healthier. Phosphorus (P) also helps plants grow bigger, but it’s primarily necessary for plants to take in water and nutrients via the stem. Potassium (K) is what keeps your healthy plants staying healthy. It’s also important because it encourages flowers, and in this case, fruits, to grow. 

When using artificial fertilizers for this purpose, it is essential to know what amount of fertilizer you need to add because too much will lead to unwanted side effects. If you’re uncertain, go for a balanced fertilizer, like 20-20-20 (N-P-K)

How to Fertilize Apple Trees Step-by-Step

Fertilizing your trees isn’t as difficult as it seems. Follow along with these steps to ensure a properly fertilized tree. 

Step One 

After you’ve determined what fertilizer to use, you’ll want to wear gloves. Fertilizers can be harmful to the skin. 

Step Two 

Read the directions of your fertilizer carefully. You’ll want to prepare the mixture base according to those instructions so that you don’t harm the tree. 

Step Three 

You’ll apply the fertilizer about a foot away from the trunk. Applying it too close can harm the tree. 

Step Four 

Lastly, spread the fertilizer about a foot away from the drip line, which is where the tree’s roots reach the farthest. 

Fertilizing for Maximum Apple Yield

From experience, you’ll want to fertilize your apple trees after planting them. That way, you can give them a boost so that they produce the maximum amounts of apples. If you’re using a fertilizer specifically formulated for apple trees, then be sure to get the recommended dosage.  

Soil pH

Planting an apple or pear tree in the proper soil will yield far more fruit than if the soil isn’t the correct pH. The first step to ensuring that you get the most out of your apples is performing a thorough soil analysis. Before performing a soil analysis, you’ll need to know the appropriate soil needed for both apple and pear trees. 

Apple Tree Soil pH

When you’re planting an apple tree, you’ll want the pH of the soil to be between 5.8 and 7.0. A pH rating of 7 is considered neutral, while anything below that is acidic. Your apple tree can survive in acidic soil above 5.8 pH, but I’ve found a neutral pH to be optimal. 

Pear Tree Soil pH

For pear trees, the pH of the soil depends heavily on the type of pear tree you’re planting. Many varieties of pear trees need a neutral pH of 7.0. Some pear trees can handle a more acidic pH of anywhere from 5.9 to 6.5. You’ll want to double-check the type of pear tree you’re planting against optimal soil pH before planting. 

Over Fertilizing Apple or Pear Trees

A good rule of thumb when fertilizing is that it’s better to apply less than more. You can always add more fertilizer, but you can’t take it away. If you over-fertilize your apple or pear trees, you might experience your trees becoming soft and fruits falling off easily when watering the tree. 

When to Fertilize Apple Trees

You can fertilize your apple trees anytime during the year, but spring is the best time. Fall is the second-best time to do so alongside spring. 

How Often to Fertilize Apple and Pear Trees

How often you fertilize apple or pear trees depends heavily on the type of fertilizer you use. If you choose granular fertilizer, you can fertilize them less often than you would with liquid fertilizer. Generally speaking, you’ll want to fertilize the trees three times during the growing season. You’ll want to wait about a month in between fertilizing.
