Buyers Guide 

Fertilizers come in all different formulas, and as such, it can sometimes be hard to sift through the plant jargon to figure out which product is most suitable for you.

To help you along with this process, we’ve put together a handy buyers’ guide. Here, we will give you all the info you need to make the most informed decision possible! Check it out below.


Main ingredients

The main ingredients you want to look out for are Nitrogen, Phosphorus, and Potassium. You may notice that fertilizers with these ingredients are often labeled as NPK fertilizers. Check out the benefits of these ingredients below.


Nitrogen is understood to nourish green leaves and promote rapid growth. It’s a great ingredient to look out for if you want quick and sturdy growth, or if the leaves of your orchid are lackluster in appearance.


Phosphorus is a great ingredient that encourages root growth, large blooms, and green leaves. If your orchid is in dire need of some TLC, keep an eye out for a fertilizer that is rich in phosphorus.


Potassium is a completely essential ingredient for orchids. Potassium promotes healthy root systems, which in turn, provide orchids with a bright, lively appearance.

If the leaves of your orchid are turning yellow, it is likely that they are low in potassium!

Active ingredients 

If you’ve been on the hunt for good fertilizer, it’s likely that you’ve come across the term ‘active ingredients’. But, what does this actually mean?

The term ‘active ingredients’ simply refers to the composition of the fertilizer. The first and most essential group of active ingredients consists of those described above – nitrogen, phosphorus, and potassium.

The second group of active ingredients is constituted of those that are still important but tend to be included in much smaller amounts than the first group. These ingredients include macronutrients, such as calcium and magnesium.

The third group of active ingredients is made up of micronutrients. These include substances such as iron, copper, zinc, and growth hormones.

These can be very beneficial, even though they come in even smaller quantities than the second group.

Type of fertilizer

Orchid fertilizer can come in many different forms. Specifically, they can be liquid, granular, capsules, or powder.

Generally, the type of fertilizer you should opt for will depend on your experience and the amount of time you are able to dedicate to plant maintenance.

If you are new to the world of orchid growing, it might be a good idea to opt for a capsule or liquid fertilizer. These are much easier to use, as they generally come in a pre-measured dosage.

This will make the process of fertilizing your orchid very easy.

If you are a particularly busy plant owner, you will want to consider using a slow-release fertilizer. This means that you generally only have to fertilize once every few months.

For the best of both worlds, opt for a capsule or liquid slow-release fertilizer! Though, always be sure to follow the manufacturer’s recommendations down to a tee.

Frequently Asked Questions 

When Should I Use Orchid Food? 

The best possible time to feed your orchid is straight after you have watered it. Specifically, the fertilizer will do best if it is applied after the bark or soil has been thoroughly submerged in water.

Should I Fertilize My Orchid When It’s Blooming? 

You can fertilize your orchid when it is producing a bloom. However, it is worth noting that the flowers of an orchid are very sensitive to fertilizer.

As such, the manufacturer will generally suggest trying to keep the fertilizer away from the flowers of the plant.

If you are concerned about this, it’s a good idea to reduce the strength of the fertilizer that you give your orchid when it is blooming.

This can be done by fertilizing your plant less frequently or lessening the quantity of the fertilizer in the fertilizer-to-water ratio.

However, if you have opted for a slow-release fertilizer, you won’t need to worry about this issue. Simply continue to replace the fertilizer whilst the orchid is blooming, if necessary according to the manufacturer’s instructions.

Should I Fertilize My Orchid In The Winter Months?

This depends heavily on the breed of orchid that you have. If your orchid grows all year round, it will be necessary to continue to feed it throughout the winter.

Although, it’s a good idea to lower the dosage of fertilizer, as it will naturally grow more slowly over these months.

How Do I Fertilize My Orchid? 

Prepare Fertilizer

First, it is important to prepare the fertilizer according to the package instructions. Ensuring that you are prepared will prevent any unwanted spillages or mistakes.

Generally, for powders or granules, you will need roughly 1 teaspoon of the fertilizer for each gallon of water.

Sometimes it can be tricky to measure out such small quantities, however, remember that too little fertilizer is far better than too much fertilizer!

If you are using a fertilizer that comes in capsule form or has a pre-measured dosage, you don’t need to worry too much about this step.

Prepare the Orchid

To prevent your orchid from sitting in a pool of fertilizer, which would cause an immeasurable amount of damage, it is important to remove your orchid from its pot. Place it in a sink or bucket to prevent too much mess!

However, it is important to note that, if you are using a capsule fertilizer, this step will be unnecessary!


This step is super important. Before fertilizing, it is always necessary to ensure that the soil or bark that your orchid is growing in has been thoroughly watered.


Using a watering can, or whatever method the package instructions suggest, apply the fertilizer to the orchid.

Focus on the root system rather than the plant itself, unless you are using some kind of spray fertilizer that dictates otherwise.


Make sure that you let the fertilizer solution drain from your orchid to prevent any damage. The best way to ensure this doesn’t happen is to leave your plant out of its container for five minutes.

Return to its container

Return your orchid to its container. Make sure that you don’t water it anymore that day, as it has received thorough hydration already!


You can then repeat this process as needed. It is best to follow the manufacturer’s instructions to ensure the best overall result.

However, it is important to be slightly over-cautious when you fertilize orchids. Although they do enjoy the boost of supplements provided by fertilization, they are also prone to damage.

For instance, if you even slightly over-fertilize your orchid, a build-up of sodium is likely to occur. This can cause your orchid significant damage.

As such, giving your orchid a rest from fertilization every now and then is a good idea.

Final Thoughts 

Orchids are a beautifully unique plant, the flowers of which can brighten up any room. However, they can be tricky to look after.

We hope that our list of the 8 best orchid fertilizers, and the accompanying info-packed buyers’ guide, help you on your way to growing super healthy, gorgeous, and long-lasting orchids.
