4 Frequently Asked Questions
#1. How Do I Apply the Best Fennel Fertilizers?
Fertilizing your garden is not as easy as pouring it from the bag onto your plants.
There are actually 4 techniques that can be used to most effectively help your plants grow.
1) Broadcast Before Planting
There are several very simple tasks involved in this technique.
- First, you will need to apply the fertilizer to the soil.
- Next, you will need to till the fertilizer into your soil.
- After this is completed, you will want to plant and then water.
- Typically, you would then apply fertilizer to your plants every 4 to 6 weeks after.
2) Row Application
The second technique to applying fertilizer to your garden is called row application.
- This again happens before you plant your garden. You will apply the fertilizer in a strip to the side of the row before planting.
- After you plant your garden you can integrate the fertilized soil into your plants.
3) Start Solution
- This type of fertilizer application made be the easiest. Very simple you dig your hole and apply the fertilizer.
- After you have applied your fertilizer you will want to transplant your plants into the hole.
4) Growing Plants Application
The final technique for fertilizing your garden is for growing plants.
- Very simply, apply the fertilizer just to the side of your plants and then water. It’s that simple.
*My only suggestion with fertilization is to never directly apply it on the plant or in the center of the plant. This could “burn” the plant and even kill it!
If you prefer watching videos to learn how to apply garden fertilizer then I recommend the below tutorial:
#2. What are the Different Types of Best Fennel Fertilizers?
Granular fertilizer is a dry fertilizer that can be applied with a spreader.
One of the benefits of this type of fertilizer is that you can see the actual fertilizer. You can also see where you have applied it and where it needs to be applied.
This type of fertilizer can be slow-release or quick-release.
Slow-Release fertilizer releases nutrients steadily over an extended period of time. This means you only have to fertilize once or twice a year.
Quick-Release delivers nitrogen immediately.
Because of this, you will need to fertilize frequently. Make sure you read the instructions of the fertilizer to have a better understanding of how to do this.
Another type of fertilizer for your garden is liquid fertilizer.
Liquid fertilizer needs to be diluted before it can be applied. It can be applied using a canister, hose, or a watering can.
It is easy to apply and is quickly absorbed.
One of the disadvantages of this type of fertilizer is that it can wash away from the rain.
So make sure to apply this when no rain is in the forecast.
The final type of fertilizer that can be applied to your garden is spikes.
Spikes are fertilizer in the shape of sticks. This is a slow-release fertilizer meaning it will be released over time.
It is applied directly to the ground and is incredibly easy to use.
This is perfect for beginning gardeners.
#3. What Should I Consider When Buying the Best Fennel Fertilizer?
Below, are 5 Tips I recommend before purchasing fertilizer:
Tip 1 – Get your soil tested!
Before you purchase the BEST Fennel Fertilizer you must first understand what nutrients your Fennel currently lack.
For this, you will want to conduct two tests.
You will first need to conduct a soil test. For this, I recommend purchasing a home soil test.
Next, I recommend continuously testing your soil. For this, I recommend a pH Meter.
Tip 2 – Fertilize with the right nutrients!
When analyzing your soil test there are numerous nutrients your fennel may need.
Below, is a list of the nutrients plants need for strong growth.
- Carbon – This is found in the air and is essential for plant growth
- Hydrogen – This is found in water and again is needed for plants to grow strong
- Oxygen – This is found in water and air. This is a key component that all other nutrients will use to help plants grow.
- Nitrogen – This is the most lacking nutrient in garden soil. This is the one nutrient that can help plants grow the fastest
- Phosphorous– This nutrient helps stimulate root growth
- Potassium – This nutrient helps plants become more disease and drought-resistant
- Magnesium – This helps plants better process sunlight
- Sulfur – This nutrient provides plants with protein. This is the building block of life
- Other nutrients that are needed for plant growth are boron, copper, iron, zinc, chlorine, and manganese.

Tip 3 – Buy the right type of fertilizer
Having an understanding of what nutrients are and how they can help your plants is important. But once you identify a deficiency it is important to decide what NPK mix you need.
NPK mix includes three nutrients: Nitrogen, Phosphorous, and Potassium.
- Typically, a fertilizer will have three digits, such as 1-1-1.
- The first digit represents nitrogen.
- The second digit represents phosphorous.
- The third digit represents potassium.
Please, see the list below to identify what typical fertilizer mix is right for you:
- 1-1-1 All-purpose fertilizer
- 1-2-1 Promotes root system strength
- 1-2-2 Promotes fruit growth and flowering
- 3-1-1 Promotes leafy growth
Tip 4 – Decide on Organic or Synthetic
My next tip for deciding on the Best Gardening Fertilizer is simple:
Buy either organic or synthetic fertilizer.
Synthetic fertilizer releases nutrients quickly and should be applied in the spring.
- This type of fertilizer comes in liquid, granular, or spikes.
Organic fertilizer releases nutrients slowly and should be applied in the fall. It typically is not concentrated meaning that the odds of killing plants are much less.
Below, are my three favorite organic fertilizers.
Jobe’s Organic All Purpose Fertilizer
Tip 5 – Learn the best time to fertilize!
While a soil test is a great way to determine what nutrients are lacking, there are other things to beware of.
- You can tell if there is a fertilizer deficiency if your plants have yellow or small leaves.
- In addition, there is a deficiency if there is poor flowering or no fruit growth.
- Finally, there is a deficiency if the plant is small.
- You can tell if there is too much fertilizer if you have all yellow leaves. In addition, there is too much fertilizer if there is poor quality fruit.
#4. Why Fertilize Your Fennel?
If you are one of the 50% of gardeners that do not fertilize, you may be asking why you should start now?
You should use one of the best garden fertilizers on this list because EVERY plant NEEDS it.
Fertilizer is a great gardening tool and a simple way to nourish your gardens.
In addition, your current land or store-bought soil may not have the correct nutrients for your plants.
Finally, common potting soil that you use to start seeds typically does not have the correct nutrients for growing plants.
As I have talked about above, there is an art and science to fertilizing.
While it is not hard, it does take time to understand how to most effectively use it for different plants.
As a reminder…
- Every plant needs fertilizer. Make sure you read the instructions and apply as needed.
- Most soil does not have all the correct nutrients for your plants. This is why fertilizer is essential.
- There are three types of fertilizer; Granular, Liquid, and Spikes. Each one meets the different needs of a gardener and you may have to use all three.
- I recommend getting your soil tested, deciding to use organic or synthetic, and what type of NPK mix you need.
- There are four types of ways to apply fertilizer: Broadcast before planting, row application, start solution, and growing plant application. You may have to use a mix of these four for best results.
- Generally, you cannot purchase one fertilizer for all plants. I recommended sticking with the best garden fertilizers listed above for your fruits, vegetables, herbs, and flowers.
