#1.Dyna-Gro Bonsai Pro Fertilizer
When it comes to the best bonsai fertilizer, the Dyna-Gro Bonsai Pro Fertilizer is the way to go. This liquid fertilizer is a really popular choice because it simply works really well. The standout feature of the Dyna-Gro is that it is more of a complete nutrient system rather than just a fertilizer with some nitrogen, phosphorous, and potassium.
It comes with 16 essential minerals needed to optimize bonsai plant growth and the results really speak for themselves. There is a reason it is raved about by many others – it works the best. Also, this stuff comes in a concentrated formula that you have to dilute yourself. Just make sure that you do it to the right ratios or you risk overfertilizing your bonsais.
#2. Perfect Plants Bonsai Fertilizer
Next up, we have the Perfect Plants Bonsai Fertilizer, which is the best bonsai fertilizer for those who want an easy to use slow release fertilizer. This 18-6-8 fertilizer comes in pellet form. What we really like about this fertilizer is that it is a set-it-and-forget-it type of deal. You place the pellets around your bonsai tree or group of bonsai trees per the instructions and then watch it grow.
These pellets are slow releasing and will continuously supply the roots with the right amount of vital nutrients. It will also lead to a lot of new growth and a thicker trunk. And if you want the absolutely perfect recipe for maximizing the growth of your bonsai tree, add in a bit of bonsai soil sold by the same company.
#3.The Bonsai Supply Bonsai Tree Fertilizer
The Bonsai Supply Bonsai Tree Fertilizer makes our list because it simply works better than most other brands and has a low failure rate. Plus, it was recommended by many reviewers and enthusiasts. So we had to give it a try to see if it at least lived up to its hype. And boy were we right. This stuff is just as good if not better than the previous two brands and it is less harmful to your roots.
This 18-4-10 fertilizer gives you super-fast results and is very easy to use. It has a slow-release formula that you just have to re-feed once a month. We are not too sure what is exactly in this fertilizer, but it certainly works very well and is loaded with micro-nutrients to help your bonsai grow.
#4. Superfly Bonsai Bonsai Fertilizer
The Superfly Bonsai Fertilizer is a pretty powerful formula that will feed your bonsai trees like no other brand. It is the best bonsai fertilizer if you are looking for organic ingredients and quality. So first and foremost, this is a 12-4-5 fertilizer, which means that it is fairly high in nitrogen content. It also contains plenty of nutrition and ingredients that optimize it for bonsai growth.
Next, please keep in mind that this fertilizer is also designed for fast growth. It is known more as a push fertilizer rather than a maintaining fertilizer, so it is better for growing bonsais. While this fertilizer can certainly be used on mature bonsais, the effects just won’t be as noticeable. And finally, we just want to point out that it continues feeding for a good 1-2 months.
#5.Tinyroots Bonsai All-Purpose Blend
Lastly, we have the Tinyroots Bonsai All-Purpose Blend, which is more of a bonsai soil than a bonsai fertilizer, but we decided to put it here because it pretty much acts like a fertilizer. The soil actually provides optimal growth for your bonsai plants because it helps with moisture support and drainage, and it is loaded with all sorts of trace elements and minerals.
And if you really want to get technical, this soil is a mix of 100% organic double-sifted compost mulch, calcined clay, vermiculite, and FRIT. It is really great for your roots as well. Overall, you can completely get away with just ditching bonsai fertilizer and swapping out traditional soil with this bonsai-specific soil.
