Which type of fertilizer should you choose for a bonsai?

Bonsai gardening is not only limited to the growing of miniature trees, but it’s also more than that. You have to deal with the shapes, methods, and arrangements. It requires great skills, care, and patience. Every bonsai tree plant is different and you need to get a suitable fertilizer for its healthy and timely growth. You should buy one that can create an optimum level of salt in the soil when you apply it. 

There are two types of bonsai fertilizers available; liquid and pellets (granular). You can choose the form which is easier for you to use on the plants. If you use a liquid bonsai supplement, then it will absorb quickly and act fast. It requires several applications though because whenever you water the plant, the liquid washes away with it. If you use pellet fertilizer for bonsai, they need to water it in while applying it dry. This type is easy to manage as you can visualize how much quantity you are applying. Both types of fertilizers are suitable for the little trees, and most gardeners use both of them for a proper balance. 

How to use fertilizer to grow your Bonsai tree?

Firstly, select the type to be used for your bonsai, whether to go for liquid or granulated, organic or non-organic. After selecting the fertilizer type, the second step is to schedule a particular time for when you will be fertilizing your bonsai and sticking to the schedule. As you fertilize, you will get familiar with the process of it and understand what your bonsai needs and what works the best for it to flourish. The more you stick with your fertilizing schedule, the better results you will get. 

You should feed your bonsai with fertilizers weekly during the growing seasons. As the growing season comes to an end, the growth of your tree will slow down and it will absorb a lesser and lesser amount of nutrients. As its growth slows down during fall, limit the feeding of fertilizer to once a month. 


There is no doubt that these fertilizers will help to make a stronger and smarter growth of the bonsai trees in your garden compared to the normal soil conditions. I have listed both the liquid ones and pellets for the trees. There are organic fertilizers as well as non-organic plant foods. There are fertilizers which have different N-P-K values to help you choose the best food according to the growth stage of your plant.
