How To Choose The Best Liquid Fertilizer for Bonsai (An Effective Buying Guide) 

You have to invest a large amount of bucks to have a bonsai as a lucrative bonsai tree is too costly. So you need to give proper nutrition to grow them properly.  Fertilizing or feeding the Bonsai means providing nutrients to the plants. So you have to choose the fertilizer carefully depending on your plant’s requirements. Let’s know some crucial criteria that you must consider when choosing the bonsai fertilizer.

Balanced Ingredients Ratio 

The best fertilizer for Bonsai should have a balanced ratio between the three vital nutrients, N-P-K. A good fertilizer also has magnesium, boron, calcium, molybdenum, and zinc. While choosing a fertilizer, check out what vitamins and nutrients they offer and consider which nutrients your Bonsai needs mostly. 

Check your plant’s growth stage

Another thing you should consider before buying any fertilizer is to understand the stage of development of your bonsai tree. If your Bonsai is still growing or developing, then choosing a high Nitrogen-based fertilizer will be great. So at the growing season or in the early spring, use a high nitrogen fertilizer. 

Otherwise, When you’re styling or pruning bonsai, Nitrogen is a must in your fertilizer. Nitrogen helps to boost your bonsai leaf at the growing phase.

But if your Bonsai is at the refinement level, choose higher phosphorus and potassium and lower Nitrogen level fertilizer. Because high potassium and Phosphorus levels help keep your Bonsai healthy and strong and produce fruits, you can easily understand the N-P-K ratio from the fertilizer packaging.

Consider the placement of your Bonsai

You can grow bonsai trees indoors or outdoors as per your taste. For the indoor Bonsai, choose the fertilizer consisting of additional vitamins and micronutrients and N-P-K because indoor Bonsai can’t get the proper sunlight and airflow. So the fertilizer should have the nutrients that fill the lack of nutrition. 

But if you keep the tree outdoors, then it gets proper airflow and sunlight. In that case, the tree needs less fertilizer than indoor Bonsai. 

Types of fertilizer

You will find two types of fertilizer on the market. One is liquid types that you have to mix with water according to the company’s suggestion to get the highest output. And another is spray type, which is ready to use. Bonsai always needs extra care. If you can manage some time, then liquid-type fertilizer is the best. But if you’re a busy person and want to feed your Bonsai most simply, then try to use spray fertilizer. 


You can also look out for fertilizer that can work for hydroponic settings along with other growing mediums. Most people have Bonsai and other organic plants for their home decoration. And using two different formulas for different plants may be costly. But luckily, we’ve reviewed all-purpose plant fertilizer that can be used on different types of plants and save a lot of bucks. 

Organic or inorganic

Between the organic or inorganic fertilizers, we recommend you to buy organic ones. You can use Chemical fertilizers if your Bonsai needs a boost. But if you continue using them, it can lead to heavy damage to the soil.

On the contrary organic fertilizers act slow and gentle, but it is risk-free from any damage, besides being effective and durable for a longer period. 

These are the common features that you have to keep in mind when buying any fertilizer for your Bonsai. So, you will be happy and satisfied with the growth of your plant.
