Fertilizers for My Garden Explained

Garden Fertilizer

Key Takeaways

  • Synthetic fertilizers provide fast-acting nutrients but can harm soil health over time.
  • Organic fertilizers offer a more sustainable option and improve long-term soil health.
  • All-purpose fertilizers (10-10-10 NPK) are suitable for most vegetables and shrubs.
  • Homemade organic liquid fertilizers can be made from materials like compost tea, seaweed, and grass clippings.

The type of fertilizer you should use for your garden depends on several factors, including your specific plants’ needs, soil conditions, and personal gardening philosophy. Generally, a balanced approach is recommended, starting with a soil test to determine existing nutrient levels and pH. For most gardens, an all-purpose fertilizer with a balanced NPK ratio (such as 10-10-10) can be a good starting point. However, for optimal results, consider using plant-specific fertilizers, especially for acid-loving plants or those with unique nutritional requirements.

If you’re concerned about long-term soil health and sustainability, organic fertilizers or homemade liquid fertilizers may be the best choice. These options provide essential nutrients while improving soil structure and promoting beneficial microorganism activity. Ultimately, the right fertilizer for your garden may involve some experimentation and observation of your plants’ responses over time. Remember to always follow application guidelines to avoid over-fertilization and potential plant damage.


The type of fertilizer you choose depends on your garden’s needs, as different plants require different nutrients that are best delivered through different types of fertilizers. For example, vegetables like tomatoes and peppers require more nitrogen, while herbs like basil and sage need less nitrogen and more potassium. Acid-loving plants like blueberries and roses require different formulas as compared to other plants. Consider using plant-specific fertilizers for optimal results.


Before adding fertilizers into your garden routine, it’s best to test your soil to find out the nutrient deficiencies and soil PH levels. Knowing what your garden lacks is an easy way to choose the right fertilizer and help your plants thrive. You may also consider adding soil amendments to improve overall soil health.

Last spring, I decided to take a more informed approach to fertilizing my garden. After years of haphazardly applying whatever fertilizer was on sale, I finally took the time to conduct a soil test. The results were eye-opening, revealing deficiencies in nitrogen and potassium that explained why my tomatoes had been underperforming. Armed with this knowledge, I choose an organic, balanced NPK fertilizer, specifically tailored to address these deficiencies. I also experimented with homemade compost tea for my herb garden. The difference was remarkable – my tomatoes flourished, producing more fruit than ever before, while my herbs grew lush and aromatic. The experience taught me the importance of understanding my soil’s unique needs and choosing the right fertilizer accordingly.


Using the wrong fertilizer at the wrong time can lead to burning of your plants. Fertilizer comes in different forms, including granular, liquid, and slow-release fertilizers, which all provide different rates of nutrient delivery, and can be used at different planting periods.


Also known as synthetic fertilizers, they are often used because they are the easiest route to a happy and healthy garden. They generally contain high levels of nitrogen, phosphorus, and potassium which can provide fast-acting nourishment for plants. However, it’s important to follow application guidelines otherwise you could end up with an over-fertilized garden. Consider incorporating sustainable gardening practices to reduce reliance on synthetic fertilizers.


An all-purpose fertilizer is a great choice for general garden use and can help get your plants off to a good start. It contains balanced amounts of nitrogen, phosphorus, and potassium which is 10-10-10 (NPK). It should be used when you first see signs of growth, and again 3-4 weeks later. Most vegetables, plants, and shrubs need this option.


Synthetic fertilizers are known to kill the beneficial microorganisms in the soil that help to cycle nutrients. This can cause an imbalance in the soil and lead to a decrease in water-holding capacity and other problems over time, such as nutrient leaching which means they can be washed away and end up in rivers or groundwater supplies.

This creates nutrient overloads, which can create algal blooms that use up oxygen and kill plants. High levels of nitrogen and phosphorus have been linked to a decrease in biodiversity, as well as the potential for long-term soil fertility decline.


Organic homemade liquid fertilizers are a great choice for those wanting to avoid chemical ingredients in their garden whether it’s a vegetable or an ornamental garden. To create your own homemade liquid fertilizer, you’ll need to start by gathering the ingredients.

This could include materials such as nettles, comfrey, kelp or seaweed, grass clippings, or compost tea. You can also add some other commonly available products such as fish emulsion or Epsom salts for additional nutrients and micronutrients. Once you have all of the ingredients together, it’s time to mix them up into a solution.

The general rule of thumb is 10 parts water to one part of each ingredient, depending on what combination you choose this could be anywhere from 1-4 teaspoons per gallon of water. Because homemade liquid fertilizers are made using organic materials, they contain various nutrients that synthetic fertilizers do not.

They provide plants with nitrogen, phosphorus, and potassium which are the three main macronutrients as well as calcium, magnesium, sulfur, and other trace elements – all of which are essential for healthy plant growth. Furthermore, these ingredients don’t burn or damage the roots as chemical-based fertilizers can. You can make large batches at once and store them in sealed containers until needed, this way you won’t have to worry about running out of fertilizer and having to make more. To further improve soil health, consider implementing crop rotation and increasing organic matter in your soil through composting.

As a kid, Joel found enjoyment in caring for the many houseplants he grew up with, learning how to transplant them safely, cloning them, and more. At about the age of 10, he wanted to see if he could sprout an orange seed from a store-bought orange and ended up using it as a science experiment in a school project. Throughout the many years of gardening, he has helped many friends and family set up their food and botanical gardens. After years of caring for plants, he was talking with other gardeners and discovering old methods of farming and botanical gardening. Joel has decided to share his knowledge for others to enjoy as he has for many years.
