What To Look for In Quality Fertilizer for Trees & Shrubs

Formula For Trees & Shrubs

Most plants can benefit from an all-purpose fertilizer, but formulas designed specifically for trees & shrubs are best. This is because they include ratios of macronutrients that support the growth of these plants. The word “for trees and shrubs” often appears on the packaging of this specialized fertilizer.

Type Of Fertilizers

The three most common fertilizer types are liquid, granular, and branched, and they are all easy to use. While liquid fertilizer can absorb and act quickly, some granules deliver nutrients quickly. Slow-release solutions help settle over time, and granular fertilizers can also be found in slow-release formulations.


When you examine the available products, you will find that they often have three numbers written on the bag or container, such as 13-10-10. These numbers represent NPK rates. 

They indicate the nitrogen (N), phosphorus (P), and potassium (K) content of the fertilizer. If you see numbers like 30 – 20 – 15, your soil contains 30% nitrogen, 20% phosphorus, and 18% potassium.

These are the most important nutrients for plant growth in large quantities. Nitrogen is the element that causes the greatest growth response in trees & shrubs, and it is usually present in the highest concentrations in fertilizers.

While all three of these nutrients are normally found in your soil, adding them can help you grow, flower, and bear more fruit. Supplementing these nutrients is especially important if your soil lacks any of these nutrients.

Plants change, and plants require different amounts of nutrients at different periods. Due to that reason, you should choose a fertilizer suitable for the plant’s requirements.

Note that it is suggested that you look at the soil’s nutrient level to check if it is lacking. After that, choose a fertilizer with the right structure for optimal plant growth.

Synthetic Or Natural Fertilizers

Chemicals in synthetic fertilizers create synthetic materials faster and more efficiently. Meanwhile, natural alternatives are produced from a variety of organic sources. They work more slowly than synthetic fertilizers, but they are less likely to harm plants.

Slow Or Fast Release

If you want to ensure that your growing and young plants get the nutrients they need, a slow-release formula is a way to go. Choosing a slow-release fertilizer is not a bad idea at all if you want the best results without harming your plants.

Safe To Use

Be mindful that the fertilizer or plant food you choose should be easy to apply and safe for your trees & shrubs. You can always opt for organic options made entirely with natural materials. They are safe for the environment and your surroundings as they are free of GMOs and harmful chemicals.

These fertilizers can also be used on fruit and vegetable patches. When used as directed, you can rest assured that the plant’s leaves and flowers won’t burn. Instead, you’ll get lush green foliage to keep your yard looking lovely.


When Should You Fertilize Trees & Shrubs?

In addition to water, sunlight, and carbon dioxide, fertilizers are needed to provide macro and micronutrients for shrubs. Before you start fertilizing the soil, carefully calculate the optimal time to feed the plants.

This depends on the type of tree. Choosing the right time is very important to stimulate your plants to flower and have healthy leaves.

Fertilize In The Spring

Fertilizing trees & shrubs in late April is probably the ideal time. Shrubs and trees have the best chance to influence new growth about a month after fertilizing in April. Before this new growth begins, the trees and bushes need to be fed.

Feed the new shoots in early spring and summer to allow the nitrogen-rich fertilizer to soak into the new shoots as they develop into healthy and vibrant shoots.

Fertilize In The Fall

Fertilizing in the fall is another great time to fertilize. After the spring period, it is time for the plant to grow further. Fertilize in larger doses after the temperature drops to 40 degrees Celsius or below to help the plant avoid freezing.

Fertilizing trees & shrubs in September or October makes them more resilient and vigor during the colder winter months.

How Often Should Fertilizer Be Applied?

The age and season will determine how often you fertilize trees and bushes. Choose a pack that provides enough plant food for your plants to last all season based on these considerations.

Besides, it is important to monitor their feeding time. Most fertilizer feed-ups last two months, while others can last up to six months.

Fertilizing plants will strengthen them during the growing and dormant seasons. It is equally important to use the right amount of fertilizer at the right time to keep your plants healthy.

What Is The Best Way To Fertilize Trees & Shrubs?

Recently-planted Tree

Since these plants are young, only a small amount of slow-release organic fertilizer will be needed to prevent tree root burn. Avoid liquid fertilizers as their release rate is the fastest. Instead, choose a granular fertilizer or other dry plant fertilizer.

Young Tree

This is the time to increase the dose of fertilizer to support the rapid growth of young plants. Follow the manufacturer’s instructions and use the amount indicated. Feeding your young plants twice a year can help them grow quickly.

Mature Tree

The growth rate of your plants naturally slows down as they mature. Since the plant can now stand on its legs, trunk, or roots, fertilizer should be reduced once every three years.
