These slow-release bonsai fertilizer pellets are a really good option if you want to use a slow-release fertilizer which can be a bit more convenient than mixing a liquid fertilizer every time you need to fertilize.

To apply these pellets it is recommended that you simply spread ½ tablespoon of the pellets over the top of the soil.

When you apply these fertilizer pellets it should take approximately 2 months for them to completely dissolve in a slow-release manner that should constantly provide the nutrients your bonsai tree needs to grow healthy.

Ideal slow release bonsai fertilizer pellets for people who want to successfully grow a wide variety of bonsai trees and they can also be used on any other container plants.

Superthrive Vitamins & Hormones

Superthrive Vitamins and Hormones (Large Size)-1 Pint (480 ml)

This Superthrive fertilizer supplement will supply 50 vitamins to your bonsai.

The bonus is that your bonsai will start to immediately feed off these new supplements almost immediately when you feed it to them.

This is not a stand-alone fertilizer, it’s designed to be added into the fertilizer you use (or water if you use pellets, etc.) and it will add extra nutrients and hormones that will make your tree thrive.

This is an ideal supplement if your bonsai is stressed or struggling to grow healthy as it is designed to encourage your plants to start producing the correct chemical balance so that they naturally start to grow by themselves.

Chelated Liquid Iron

Liquid Chelated Iron<br>8 oz. concentrate

Liquid chelated iron supplement is ideal as a preventative measure or also as a cure if your bonsai is struggling.

If the leaves on your plant are pale green or yellow there is something wrong as a strong and healthy plant should have dark green leaves.

If you have diagnosed the problem that is preventing your plant from growing healthy as chlorosis then this is the ideal supplement for your plant.

The iron that this supplement will provide will immediately get to work and improve your plant.

If you just want to use it as a supplement to keep your bonsai as healthy as possible you should dilute ½ teaspoonful into the water and add it once per month.

Personally I do use this supplement as I feel it is better to use it as a boost to keep my plant healthy rather than wait until it is showing signs of iron deficiency.


  • This is an additional supplement and not a fertilizer
  • Can be used to treat chlorosis in plants
  • If your plant has yellow or light green leaves this could be the solution
  • Can be used as a preventative measure to keep your tree healthy

Rooting Hormone Concentrate

Rooting Hormone Concentrate - 2 oz (60ml)

Drip n grow is the rooting hormone I use to create new bonsai out of cuttings, which can be a challenging but satisfying experience.

If you are making your own bonsai trees from cuttings then you will definitely need to use a rooting hormone if you are to have any chance of success.

There are many rooting hormones that come in powder form but I find this liquid rooting hormone is a better option and I have had more success when using it.

Because it is a liquid it is absorbed more quickly and easily into your future trees where it can start to boost the growth of the roots.

You should only use this rooting hormone on ornamental trees such as bonsai as it does contain chemicals that you may not want to get into your food supply.

When using a rooting hormone it will dramatically increase the chance of your trees growing roots however other factors such as the correct temperature also play an important role.


  • Liquid rooting hormone is more easily absorbed than powder
  • When you successfully create a new tree it’s incredibly satisfying
  • You should only use this rooting hormone on ornamental trees
  • Using a rooting hormone does not guarantee success if other factors like temperature are wrong

Organic Neem Oil Concentrate

Neem Oil Organic Concentrate<br>8 Ounces

Organic neem oil comes from the mystical neem tree, a tree that has all sorts of uses in the environmental protection field and new uses are still being discovered.

When it comes to bonsai or gardening in general neem oil can be used as an organic method to control many diseases or problems such as black spot, powdery mildew, fungus, and a wide range of insect infestations.

This is a large bottle of concentrate so you will have to dilute it before you use it and you should add 4 teaspoons of the mixture per gallon of water.

One method of applying it is to use a spray bottle and if you use this method you should add some liquid dishwashing soap (yes dishwashing soap) as this will actually make it more effective.

Even if your plants do not have any problems currently it may be a good idea to use neem oil as a preventative measure as prevention is always better than a cure.


  • Neem oil concentrate so you will need to dilute it before use
  • Can be a cure for many types of fungus, mildew, or blackspot
  • Neem oil can be used as a preventative supplement or as a cure
