If you love to do gardening, then you would also like to see the rewards. Sadly, most of the time, it takes quite some effort and time to see a blooming garden. Though your plants have sufficient rain and sunlight, most of them do not grow as you like them.
They need that little push to grow as they should and make you highlight them to your neighbors with glee. At the same time, some trees and shrubs grow rightly. But, giving them that additional boost helps in healthy growth.
It is not surprising that hobbyists and professional gardeners recommend the usage of fertilizers. That is easier said than done because finding the best fertilizer for tree and shrub needs ample research and time.
The good news is that we have gone through some of the best products available today. You can now relax and read through the post to find out more about how fertilizers help your trees and shrubs to grow healthy.
It is safe to say that plants are investments for a nature lover. Every year, you tend to love them more as you watch them grow. Unless the plants are correctly planted and chosen, they cannot be expected to thrive in your garden. Though you water, fertilize and prune them, they may not grow as desired.
Often people make the same error of misunderstanding that fertilizer is magic for plants. Once the fertilizer is used or applied on the soil, the plants grow instantly. Well, it does not work that way.
As you know, plants produce or make their food through the process of photosynthesis. So, supposing the minerals are lacking, fertilizers are added only to balance the nutrients in them.
What Are The Best Fertilizers For Plants?
Homeowners like you and me, always prefer and like instant results in life. Whether it be relief from a nagging pain or skincare, the moment we see an advertisement about immediate relief from pain or agony, we go ahead and purchase it, without even bothering to read the ingredients or price.
Probably, the same can be said about plant fertilizers. Many gardeners and homeowners rely on the assumption that fertilizers can cure the problems faced in trees and shrubs. You feel that it can cure everything.
However, that is not the case. There is a perception that fertilizers can work on plants and produce instant results. You need to realize that there is a place for the compost, but not one fertilizer doing all the tasks.
1. Regular Soil Test
Before we begin our hunt for the best fertilizer for trees and shrubs, you need to first find out the right kind of fertilizer for your garden or region. This is one of the main reasons why gardens tend to appear the same, despite adding the best quality fertilizer.
The simple fact is that the fertilizer is not meant for any region and plants. That is why you need to do a regular soil test to determine the type of fertilizer your garden needs. The soil test tells you a lot about your garden soil.
Consider factors like acidity, the fertility of your soil, and so on. Only when you are aware of these factors, you can think of taking the next step. This way, you can understand how you can balance the pH out.
Depending on the appearance and color of the plants, you need to add fertilizer. If you see that your plants have yellow-colored leaves, broken twigs, and small-sized leaves, then you need to put some fertilizer to them.
The reason for that is due to an increase in pests, your plants are most likely infected with diseases. The fertilizers are not going to become a magic wand and add life to your plants. Unless your plants are in good condition, the fertilizers might not do their required job.
2. Release Designs Of The Fertilizer
Since you now know the need for adding fertilizers to your plants, you must beware of your options. When your soil’s potassium and phosphorus levels are average, then you can make use of a complete fertilizer.
Usually, the fertilizers come as extended-release or fast-release. The extended-release fertilizers take time to work effectively on your plants. Unlike them, the fast-release works immediately.
You can notice the results within a day or two. They remove most of the nutrients from the soil. However, they do not cause damage. These kinds of fertilizers work well on well-watered earth.
The extended-release fertilizers take much longer to give their effect. However, they are ideal for plants of all kinds because they slowly give way for new plants too. If you have recently planted some shrubs, then this kind of fertilizer is very suitable.
At the same time, the fast-release fertilizers show their magic quickly. They are ideal for plants that are well grown and need that shot in the arm. Hence, it all boils down to the growth stage of your plants.
Depending on your requirements, you will want to decide on purchasing the fast-release or extended-release fertilizers for your garden.
3. Usage Of Natural Fertilizers
Another alternative is using natural fertilizers. They include composted materials or cow dung. Though they are the right source, they do not come with essential ingredients like potassium, nitrogen, and phosphorous.
They contain zinc and iron too. These elements are good for the soil. As you can see, there are pros and cons when using these kinds of natural fertilizers, which are typically not found in markets.
Thus, you need to read the contents of the fertilizer before making the purchase. These act as repellents on the weed.
Besides, once you have added the compost, do not expect immediate effects. Wait for nature to work in its own time.
Also, the season plays a crucial role in this process. If you have applied the fertilizer during summer, then it may take some time. However, if you have used the fertilizer during the rainy season, then you can notice the effects slightly quicker.
Fertilizer Application Methods
You can apply the best fertilizer for trees and shrubs directly or indirectly. However, the method you use does not matter because, eventually, you have to apply it around the root region. For any plant, the root is the main source of nutrients.
The roots feed close to 10-14 inches above the soil. Applying the fertilizer to the mulch helps the cause during rains.
You must make sure that when applying the fertilizer, irrigate the soil immediately so that it dissolves on to the plants. Otherwise, the nitrogen will be lost into the atmosphere.
1. Indirect Fertilization
This happens when the plants are fertilized in your garden and also when you scatter the fertilizer in and around your garden.
So, the water, air, and other components carry the fertilizers to the plants. However, it is not a completely effective method.
2. Direct Fertilization
This is an effective method of fertilization because the fertilizer is absorbed by the plants properly. With the drop-type spreader, the ideal amount of the compost is used to spread on the complete root zone area.
Professional gardeners split the fertilizer into half the amount to be sprayed and then scatter it in one direction and then other-half in the other direction. However, when you want to apply fertilizer on shrubs and other plants, you need to ensure that you brush off the leaves using a rake or broom to the ground.
You can apply the fertilizers in the liquid form. This is a standard method to apply fertilizer.
Gardeners need to understand that merely using the compost will not cure the deficiency. You can do a soil test to determine the pH levels and decide on the amount of fertilizer to enforce.
Signs That Trees And Shrubs Are Lacking Nutrients
As a homeowner or gardener, when you notice the following signs in your trees or shrubs, then you must understand that they need additional nutrients in the form of fertilizers. Actions taken on time will enable you to improve your garden’s overall condition. Here are those signs:
- If the growth of the twigs is shorter than the actual size.
- When the leaves are undersized or a few in numbers.
- The tips of the branches lack life.
- The veins of the leaves become darker than the margins of the leaf.
- If the leaves are other colors like yellow, orange, or purple.
Please keep in mind that despite adding fertilizers, if your plants do not have any noticeable difference in them, then you might want to consult a professional gardener. He can provide you with the actual cause for it and give an official diagnosis.
Through this article, we will discuss some of the best fertilizers available in today’s market. You can decide and use the ideal product for your plants.

FAQs on Fertilizers for Trees and Shrubs
1. Why Do You Need To Add Fertilizers To Your Trees And Shrubs?
This is a common question posed by several homeowners and even farmers. The main reason for doing that is because; fertilizers enable trees and shrubs to remain robust and healthy. Though trees are strong and sturdy, external factors can contribute to their poor health.
External factors like sun, wind, rain, and pests. Poor health becomes quite visible over a period of time. However, adding good quality fertilizers to them ensures that the tree can withstand the changing weather patterns and adjust accordingly.
2. Do Trees And Shrubs Need To Be Fertilized In Your Garden?
It depends on the region you live in. It is because forests have nutrients in the soil of a higher grade as compared to garden soil located in towns and cities. When you remove the twigs, leaves, and other bark from your garden, you are actually eliminating nutrients that can be used for recycling in the garden.
Not to mention, the grass present in the garden often utilizes the water and nutrients that are required for the trees and shrubs. When you fertilize your plants, they bring about the same cycle that occurs in the forest.
3. When Is The Ideal Time To Fertilize Plants?
Most of the fertilizers come with elements that are suited throughout the year. The fertilizers are tested in labs before being sold in the market. So, on using these formulas, there is no need to worry about the ideal time for fertilization.
However, if you reside in a tropical region, then you need to ensure that you water your plants quite often. Similarly, when you stay in a cool part of the country, then you might want to use the right kind of fertilizer for your garden.
4. Which Fertilizer Is Ideal For Your Tree?
The ideal fertilizer is the one that works slow. In layman’s terms, it comes with a low salt index and has a controlled release. Some of the key ingredients in fertilizers are phosphorus (P), nitrogen (N), and potassium (K).
Some fertilizers also come with amino acid and PPA. In certain regions, trees lack macronutrients. If you live in a similar area, then you need to ensure that the trees and shrubs are provided with those nutrients.
This concludes our review of the best fertilizer for trees and shrubs. Hope you understood the different kinds of fertilizers available in the market. You would have also read about the need to use fertilizers, when, and how to use them.
However, if you are still not sure about what or how to use them, then you can take the help of a professional gardener. Your ultimate goal is to bring up a healthy garden with flowering plants and sturdy trees.
That can happen only if you use the right kind of fertilizer ideal for your region and climatic conditions. At the same time, you need not feel annoyed or frustrated when the fertilizer is not helping your garden to be the way you want it.
Remember, these fertilizers take time by working from the roots. Depending on the soil, climate, and nutrients, they will work in their own time. This is when you might want to take a look at the base of the trees and shrubs.
So, with the right base, the suitable fertilizers, and the ideal climate, your garden will bloom one day, making you the envy of the entire neighborhood.
