Plants require a lot of nutrients, water, and adequate sunlight to grow. Sometimes, the conditions in the soil are not favorable for growth and may require an extra nutrient boost.
When growing a vegetable garden, you need to consider the best source of nutrients for them. Liquid fertilizers are one of the best sources of readily available plant nutrients. In this article, we will discuss the best organic liquid fertilizer for vegetables, lawns, and gardens.
What Is an Organic Liquid Fertilizer?
Organic liquid fertilizer is a source of nutrients made from plants and animal manure or animal by-products. It is called organic because it is made from natural materials and is not concentrated.
They are safer but more expensive than inorganic fertilizers. Organic fertilizer regularly includes crushed shells, worms, seaweed, ground bones, guano, peat, etc.
Organic fertilizers are sustainable and help the environment by balancing carbon and nitrogen levels in soil, which boosts its fertility. Its ability to remove carbon from the soil and atmosphere (through carbon sequestration) reduces the greenhouse effect and global warming.
They do not disrupt the balance in the soil because there are no traces of artificial elements in them, unlike inorganic fertilizers.
Benefits of Organic Fertilizers
- They do not overfeed your plants because plants absorb them slowly
- They improve the soil structure to create a better environment for plants to thrive
- They increase the bacterial and fungal activity in the soil
- They are safer and healthier than chemical alternatives
- They are eco-friendly
- They reduce the build-up of toxins
- They make the soil fertile for planting

What to Consider Before Buying Fertilizer for Your Vegetables
You need to pay attention to certain factors before you decide to buy fertilizer for your plant. In the long run, these can determine whether or not your plants will show improvement after the fertilizer is applied. These factors include:
There is a wide range of sizes of fertilizers you can choose from. When buying one from any brand, make sure to get one that won’t last much longer than you need. Some plants will require different types of fertilizer for different growing stages.
On the other hand, you do not want to get surplus fertilizer that will end up going bad.
To ensure you’re getting the right size of fertilizer, find out the duration you will need it for. Measure the size of your vegetable garden, then consider how often you’ll use it. All these will help you pick the right size.
Fertilizers serve as a source of food for your plants. They play a huge role in your plant’s survival. It is not just your plant’s health you need to be worried about. Harmful chemicals like lead, Barium, Chromium, etc., can cause health problems to humans and pets.
It is important to do extensive research on the brand of fertilizer you wish to purchase before making your purchase.
There are three forms of fertilizers — liquid, solid (granular fertilizers), or gaseous. Each of these forms has its benefits and downsides. Before you get a fertilizer, determine what form will be convenient for you to apply.
Some people prefer solid fertilizers because they are easier to apply. Gaseous fertilizer will be less suitable for indoor use but great for a large vegetable farm.
Once you’ve determined how your fertilizer preferences look, you can narrow your search to the best brands that specialize in that fertilizer form.
4. NPK Level
NPK is a ratio percentage that shows the level of three key ingredients in fertilizer. They are nitrogen, phosphorus, and potassium. These ingredients are integral to ensuring the proper development of plants by providing them with nutrients and resisting diseases and pests.
5. All-Purpose Fertilizer
It is not crucial to buy an all-purpose fertilizer, but it would be helpful if the fertilizer you choose is good for indoor/outdoor plants, shrubs, vegetable gardens, etc. It reduces the cost of having to buy more than one fertilizer, as well as the effort.

Some fertilizers have limited storage life, while you cannot store others in their diluted form. Before getting any type of fertilizer, ensure it has long storage life to accommodate your needs.
