Can You Use Baby Bio on Bonsai Trees?

Baby bio is a high-quality fertilizer that can be used on bonsai trees to promote growth. In addition to the basic care practices like proper watering, pruning, and correct location placement, fertilizing your Bonsai tree will help your Bonsai to become healthy and strong.

Bonsai trees are some of the most impressive and creative plants you can cultivate on an intermediate level. However, bonsai trees can be quite a finicky plant to cultivate, especially depending on which species you decide to go with. There are a few things you can do to help get the most out of your Bonsai tree, however. 

Fertilizers are not all created equally, and some can be too aggressive for your tree, particularly if your Bonsai is new or if it is in shock from too much change.

Bonsai tree art can be especially rewarding if you know what you are in for, and even if you are a seasoned cultivator, read on to learn a thing or two about Baby Bio and Bonsais.

Can You Use Baby Bio on Bonsai Trees? 

Fertilization of your Bonsai tree is a great way to keep branches strong and foliage lush and full.

Finding the right fertilizer for your plant’s specific needs is essential to its health, but there can be many factors to take into account when choosing a fertilizer, so it can be difficult for novice or beginner plant parents.

Especially if you are keeping a Bonsai tree that prefers to be indoors, your plant might require supplemented nutrition from a fertilizer. If you are looking for an excellent fertilizer, then you should consider Baby Bio fertilizer. 

Baby Bio Bonsai Food is a great choice for both indoor and outdoor trees as it is gentle enough for monthly use for indoor plants, or can be used as needed during active growing seasons for outdoor plants.

Providing your Bonsai with proper nutrition can also help your plant to be strong enough to fight off or at least prevent pests and disease.

Baby Bio should only be used as the Bonsai is actively growing to support the healthy progress of your tree, meaning that it is not necessary to use during a tree’s dormant period.

Obviously patience is key when training a Bonsai, and too much too soon will cause shock, wires to cut into the bark, and even death for your little tree.

Particularly if you are actively trying to train your Bonsai to grow a certain way, Baby Bio is good for repairing and encouraging the results you want out of your plant.

What Makes a Good Fertilizer?

A good fertilizer is honestly the one that you will use. If you do not set a schedule to fertilize your Bonsai, the bottle is doing no good to anyone just sitting under the sink.

You may have to test out a few different fertilizer brands to find the one that your Bonsai likes the most, but Baby Bio seems to be a great place to start.

Where larger trees have the ability to dig their roots down deep into the earth, bonsai trees are homebound in a pot or shallow dish and need an extra amount of nutrients in order to thrive as their big, wild siblings would. All fertilizers contain a specific amount of three different elements that help Bonsais to grow to their full potential:

  • Nitrogen (N)
  • Phosphorous (P)
  • Potassium (K)

These three elements help the Bonsai tree to convert water and sunlight into all the nutrients they could need through photosynthesis.

Different ratios of these three elements will do different things for different plant species, and even different Bonsai species. The best fertilizers will tell you the NPK value that is contained within the bottle.

NPK Values and Meanings

A common NPK ratio between fertilizers is 10N-9P-10K, meaning 10% nitrogen, 9% phosphorous, and 10% potassium.

Different brands of fertilizers will have various ratios of elements that will, in turn, get you varying results. Each element has its own special job in the process to ensure that your Bonsai is healthy, happy, and growing properly.

ElementElement Responsibility 
NitrogenHelps produce leaves and keep them green
PhosphorusStrengthens roots and helps prevent disease
PotassiumHelps stimulate the plant’s desire to flower

Baby Bio’s NPK values are 10.6N-4.4P-1.7K. This higher amount of nitrogen keeps your Bonsai looking full and green, while the potassium levels can be lower since few Bonsais actually flower. 

A good thing to keep in mind when considering a fertilizer and the process by which you will feed your Bonsai is that fertilizer is like super concentrated superfoods for your plant.

As much as you may love dark chocolate, salmon, or any other superfoods, you would get sick if that is all you ate in excess for an entire week.

You should also only feed a healthy Bonsai. If your plant is suffering, figure out the source of the problem and allow it time to heal before introducing any fertilizers into its diet.

Fertilizer will only help your tree if you are keeping up with the proper watering, lighting, and temperature needs of your plant.

Tips for Proper Fertilization


Strong ingredients make it so important to properly dilute your fertilizer and water your Bonsai before feeding to avoid burning the roots.

As you have probably heard before, too much of a good thing is just too much of a good thing. To make sure the growth of your plant is not too intense, use a fertilizer that has a proper amount of nitrogen. 

Baby Bio happens to be one of these fertilizers with the perfect amount of nitrogen for feeding your Bonsai without the negative repercussions or extra, unnecessary ingredients.

Baby Bio Bonsai is the best formula for your tree, but the regular household formula of Baby Bio will do the trick as well. Either one of these formulas will:

  • Keep your Bonsai growing at a steady and healthy pace
  • Strengthen and protect your Bonsais roots and branches
  • Encourage the best and healthiest foliage

When diluting your fertilizer, a good rule of thumb is to use 5ml of liquid fertilizer to a litre of water.

This will not only help prevent root burn of your plant but will help the Bonsai to quickly absorb all the nutrients. It is worth mentioning, however, that following the instructions on the outer label of your fertilizer should always take precedent.

Again, not all Bonsais will need to be fed the same amount and in the same way. Indoor Bonsais will need the extra supplements every week, year-round, while outdoor plants only need weekly treatments once a week during the growing seasons.

As fall fades into winter, your outdoor Bonsai should be fertilized only once a month as it hardly grows.

Once you have mastered the art of watering as needed, and once you have found the perfect sunny place for your plant, you can feel assured that your Bonsai is strong enough to introduce a fertilizer to get the absolute best health out of your little potted tree.

Baby Bio is an excellent choice for a Bonsai feeder, provided you research the kind of Bonsai species you have.

If you are able to stick to a regular fertilizing schedule, only feed when healthy, and only feed when the plant is actively growing, you can have one of the healthiest and strongest Bonsai trees ever.
