Our guide on how to fertilize plants will help you choose the right type of fertilizer for your plants and show you when and how to apply it for maximum effect.

How to add nitrogen to soil
Nitrogen is an essential element for plant growth and is often the limiting factor in plant growth.
Adding nitrogen to the soil can be done through many different methods, including:
Adding organic matter such as compost or manure
One of the best ways to add nitrogen (and other nutrients) to the soil is by adding organic matter.
Organic matter decomposes over time and releases nutrients into the soil that plants can use.
Some good sources of organic matter include:
- Compost
- Manure
- Leaves
- Grass clippings
- Wood chips
Using chemical fertilizers
Another way to add nitrogen to the soil is by using chemical fertilizers.
Chemical fertilizers are available in many different forms, including:
- Ammonium sulfate
- Urea
- Ammonium nitrate
- Anhydrous ammonia
Planting cover crops
Cover crops are plants that are grown specifically to add nitrogen to the soil.
They are usually planted in the fall and plowed under in the spring before planting the main crop.
Some common cover crops include:
- Clover
- Alfalfa
- Ryegrass
- Oats
Using legumes
The best method of adding nitrogen to the soil will depend on your specific situation.
Legumes are plants that have a symbiotic relationship with bacteria that live in their roots.
These bacteria convert nitrogen gas into a form that the plant can use.
Some common legumes include:
- Beans
- Peas
- Lentils
- Soybeans
- peanuts
When to fertilize plants

The best time to fertilize your plants will depend on the type of fertilizer you’re using.
Organic fertilizers should be applied before planting, while chemical fertilizers can be applied at any time.
If you’re using a cover crop, it should be plowed under in the spring before planting the main crop.
Legumes should be planted in the fall so that they can establish a symbiotic relationship with the bacteria in the soil before the main crop is planted.

How to add potassium to plants
Adding potassium to your plants is important for several reasons. Potassium helps the plant take in water and nutrients, strengthens the plant’s stem and branches, and increases the plant’s resistance to disease. Without enough potassium, your plants will be more susceptible to pests and diseases. (3)
There are a few different ways you can add potassium to your plants. You can use a commercial fertilizer that contains potassium, or you can add potassium-rich materials to your soil, such as wood ashes or compost. You can also find products that contain potassium sulfate, which is a type of potassium fertilizer.
To use a commercial fertilizer, follow the directions on the package. Be sure to apply the fertilizer to the soil, not the leaves of the plant. Applying fertilizer to the leaves can burn them.
If you’re adding potassium-rich materials to your soil, mix them in well before planting. You can also add these materials to existing plants by top dressing the soil around the plant. Be sure not to put too much material on the plant, as this can also burn the leaves.
When adding any type of fertilizer to your plants, it’s important to do a soil test first. This will help you determine how much potassium your plants need. Once you’ve determined the amount of potassium your plants need, you can add the appropriate amount of fertilizer. Too much potassium can be just as harmful to your plants as too little.

1. Collect the manure in a clean container
If you’re using fresh manure, make sure it’s from a healthy cow. Collect the manure in a clean container, such as a bucket or wheelbarrow.
2. Add carbon-rich materials
To help the composting process, add some carbon-rich materials to the manure, such as straw or leaves. This will also help to absorb any odors.
3. Mix the materials together
Thoroughly mix the manure and carbon-rich materials together.
4. Add water
Add enough water to moisten the mixture, but not so much that it’s soupy.
5. Allow the mixture to compost

Fertilizing a lawn is an important part of keeping it healthy and looking good. There are two main types of fertilizer: organic and inorganic. Organic fertilizers come from natural sources, such as animal manure or compost, while inorganic fertilizers come from synthetic or chemical sources.
When choosing a fertilizer, it’s important to consider the needs of your lawn. For example, if you have a lot of clay in your soil, you’ll want to use a fertilizer that’s high in phosphorus to help promote root growth.
It’s also important to consider the time of year when fertilizing. In general, it’s best to fertilize in the spring and fall, when the grass is actively growing. However, you may need to fertilize more often if your lawn is under stress from heat, drought, or heavy traffic.
To apply fertilizer, use a spreader to evenly distribute it over the lawn. Be sure to follow the manufacturer’s instructions on how much fertilizer to use. Over-fertilizing can damage the grass, so it’s important to not use more than the recommended amount.
After fertilizing, water the lawn deeply to help the fertilizer reach the roots of the grass.

How to fertilize houseplants
Fertilizing houseplants is important to keep them healthy and growing. While most plants will do fine without being fertilized, they will benefit from a regular feeding during the active growing season. Use a water-soluble fertilizer and follow the package directions for best results.
Watering your plants before fertilizing them is always a good idea. This allows the fertilizer to be absorbed more easily and prevents it from burning the roots of your plants.
Apply the fertilizer around the base of the plant, taking care not to get any on the leaves. Be sure to water thoroughly after applying fertilizer so that it can work its way down to the roots.
Final Thought
Although organic matter is the key to healthy soil, there are other ways to amend soils that are low in organic content. In some cases, you may need to use a synthetic fertilizer in order to get your plants the nutrients they need to thrive.
With a little bit of research and planning, you can create a lush and thriving garden using natural methods – and without harming the environment in the process.
