Relying on soil alone isn’t enough to keep your plants healthy; that’s why it’s important to supplement their growth by providing the necessary nutrients they need to thrive. These come in many forms, but they’re all considered fertilisers, which essentially act as a food source for plants. With that in mind, giving the right amount of fertilisers is crucial in your bonsai care, but you can’t throw in all the nutrients blindly and expect to see quality results. 


Before You Choose a Fertilizer, Consider This…

As mentioned above, there are different kinds of fertilisers, and part of the proper feeding process for your bonsai involves choosing the ideal nutrition it currently needs to achieve healthy growth.

Fertiliser requirements vary depending on the plant species, but most bonsai trees need nutrients that help promote overall health and boost growth. These can be readily found in chemicals like nitrogen, phosphorous, potassium, calcium, and magnesium.

With that being said, you need to know the available nutrients in your compost and soil before deciding on which fertiliser will help your bonsai. Here are some different nutrients you can consider for your bonsai’s fertiliser of choice:


Nitrogen [N] 

Nitrogen is as essential as carbon and oxygen, but unlike the two, it’s not a major part of the air we breathe. It is, however, a vital part of plants, which uses it for activity. Nitrogen is the workhorse that transports the energy that makes the plant grow and be healthy. This process is possible because it releases energy stored through photosynthesis, providing the plant with energy for growth. 

In the case of bonsai, nitrogen is crucial in developing healthy green leaves. Your bonsai will be able to produce more leaves due to the presence of nitrogen in its soil. From there, we can conclude that more leaves translate to more photosynthesis, which leads to an increase in growth.


Phosphorus [P] 

Phosphorus plays another important role in the development of leaves, but it’s most beneficial to flower and fruit production. It helps increase the vigour of your bonsai, allowing the plant to bloom with flowers and bear fruit.

In the case of your bonsai, you can expect to see a flower bud or two pop up after a few months of using a fertiliser that contains phosphorus.


Potassium [K] 

Potassium is a nutrient that’s closely connected to the boost in photosynthesis. It helps the plant activate its process of making food, giving your bonsai a well-rounded diet that helps it bloom in all aspects. It’s a vital component in producing carbohydrates, proteins, and other important compounds that all plants require.


The Bottom Line: Take the Time to Understand Your Bonsai’s Needs 

Since every bonsai is different, you need to analyse the nutrient content of your compost and soil to determine what your bonsai really needs to achieve healthy growth. You can’t take a one-size-fits-all approach when it comes to proper bonsai care. 

Remember to choose the right fertiliser for your bonsai tree, and don’t rush the process. Don’t forget to feed your bonsai tree with the appropriate amount of fertiliser, as overdoing it can do more harm than good. In essence, balance is the key to achieving healthy growth for your bonsai.
