0 872

Are you feeling lost between the sea of hundreds of orchid fertilizers on the market, and you don’t know which is the best orchid fertilizer for you? No worries, I am here to guide you out of that maze.

Orchid is a beloved flower with elegance, nobility, and strength as its special symbolizing meaning. That is why this plant is also indispensable in almost every garden of flower lovers.

Orchids in the wild get many nutrients from bark, rotting leaves, bird droppings, dead insects, fungi, lichen, and nutrients from rainwater.

When you grow orchids in-house, the substrate is usually very clean, like pine bark, bamboo tree, driftwood, terracotta pellets, etc. Thus, fertilizing orchids will achieve better development efficiency.

Top 8 Best Orchid Fertilizer in 2022

To assist you in taking care of your orchid, here are the top 8 fertilizers you have been waiting for:

Miracle-Gro 100195 Ready-To-Use Orchid Plant Food Mist- Best spraying fertilizer

Spraying Miracle-Gro Ready-To-Use Orchid Plant will instantly provide moisture and nutrients to your indoor orchids. The formula is 0.02-0.02-0.02, which won’t burn the plant leaves and serve as a supplement on misting days instead of pure water.

This foliar fertilizer is the most convenient way to feed your plant since mixing can be somewhat a hassle. All you need to do is spray around the leaves, stems, and soil once a week in addition to daily watering. However, you can use it seven consecutive days to see the best result.

One great advantage that I found is that the broken plant will rebloom and come back to vibrant life again with the help of the Miracle-Gro Ready-To-Use Orchid Plant.

Importantly, this type of fertilizer is not suitable for orchid blooms. Make sure that you avoid the flower area while spraying.

Note: Some people might be confused about a white toggle button located on the bottle’s neck. To get the spray to work, you must press the toggle. Safety on, safety off. That’s a little helpful detail for you if needed.


  • Easy to use
  • Effective for indoor flowers
  • Could revive broken orchids


  • Not applicable on blooms

Miracle-Gro 1003661 Orchid Plant Food Spikes- Best budget-friendly choice

Maintenance of the plant during the growing process is crucial. Therefore, this plant food is an ideal fertilizer for those active-growing plants which are flowering or developing new leaves, shoots, or roots.

The way to use this orchid food is utterly simple: break the stick in half, gently press the two pieces into the pot, distribute them equally between the plant and the pot’s edge.

This fertilizer has the balance NPK formula of 10-10-10. Once every two months, you need to refresh another new spike as a way of maintaining nutrients. The red sticks make them easy to notice if they are in the soil or decomposed and need replacing.

Due to low light conditions from October to February, you should reduce the application rate by half. Stick to a strict consumption schedule to see the best result of your orchids.

However, the packaging may have been resealable because all of the sticks cannot be used simultaneously – a point the manufacturer may want to consider improving.


  • Simple to use
  • Excellent for active-growing plants
  • Easily recognizable for replacing
  • Suitable for indoor orchids


  • Improvable packaging

Orchid Love- The World's Greatest Orchid Food

Please give the bottle a good shake before using as it contains many particles that settle to the bottom. Although this fertilizer has a new deodorized formula, its smell remains slightly unpleasant.

The manufacturer has addressed it, and while the concentrate is very unlikely to become the next bestseller in the perfume department, it is manageable, especially once it is diluted. And frankly, this minor downside is to be expected from an organic fertilizer.


  • Effective in reblooming
    Excellent NPK formula
    Easy to mix


  • Unpleasant smell

Espoma Company ORPF8 Organic Orchid Plant Food – Best liquid fertilizer

Espoma Company Organic plant foods are made from hydrolyzed soy protein, fish protein, and poultry waste, as well as potassium sulfate, bone meal, and kelp extract, which are readily available to plants.

1-3-1 is the N-P-K ratio in this liquid fertilizer. Additionally, it includes a range of additional active ingredients such as a host of microbes and calcium.

Espoma ORPF8 orchid food has various non-plant food ingredients (bacillus licheniformis and humic acid), beneficial for orchid health. Nonetheless, keep the product out of children’s reach for safety due to its non-plant ingredients.

Aside, you don’t have to be worried about measuring because it contains pre-measured product doses. Every 2-4 weeks, add one dose (7 ml/ 0.2 fl oz) per quart of water and feed your plants. It is very convenient to measure for application and easy to use.

Note: Since this fertilizer is organic and builds up gases inside the tank, it can burst when you open the lid. The better way is to shake the bottle, turn it upside down, open the lid, and pour the product in a bottle.


  • Great nutritions needed for your orchid
  • High-quality ingredients
  • Pre-measured doses for ease of use


  • Many non-plant ingredients

Furthermore, it is easy to use. By following the instruction at the back label for the proportion of water and fertilizer, you will see positive outcomes on your orchids.

If your orchid is in its infancy or developing stems, I would encourage you to use another plant food as the sapling does not need the high P content found in this product.


  • Economical price
  • Urea-free
  • Best for flowering stage
  • Uncomplicated usage
  • Measuring spoon included


  • Not recommended for small flowers

Sun Bulb Company 8303 Better Gro Orchid Plus

According to the package, you may fertilize in a while-about once a month with 1 tbsp per gallon. I prefer to water weekly-weakly, the other recommended method, about one teaspoon per gallon when watering.

Soon your mini orchid should start growing a new leaf or two and some new roots at this time of year, and the fertilizer will help it along.

On the other side, the package would not seal properly to store and avoid leaks or humidity absorption. To hold it airtight, I had to move it to a jar.


  • Ideal for young orchids
  • Lots of nitrogen for fast growth
  • Simple to work with
  • No urea in source of nitrogen
  • Affordable price


  • Better if having tight zip

Follow the suggested application; your plants will absorb an adequate amount of nutrition. You may want to repeat the process every 14 to 20 days, with 1-2 capsules for small plants, 2-4 for medium plants, and 4-8 capsules for large-sized ones.

Once the plant has been well nourished, it can improve the absorption from direct sunlight to generate chlorophyll, encouraging the plant to turn green almost instantly.

In addition to being green and stable, this fertilizer aids the orchid in growing gradually and sprouting new buds as soon as possible.

However, the one little problem I have is its price. It won’t be the most economical product if you have a garden with many orchids.


  • Easy to fertilize
  • Eco-friendly
  • Effective with both indoor and outdoor orchids
  • Child and pet-friendly
  • Great for a deep green color
  • Odorless

Last but not least, the best fertilizer formula for orchids belongs to Osmocote Smart-Release Plant Food Plus Outdoor & Indoor with a balanced N-P-K 14-14-14. This product can fertilize all kinds of flowers. Most noticeably, it works flawlessly with orchids.

Osmocote Smart-Release Plant Food Plus Outdoor

It is so much easier to feed the plants with a sprinkle cap. Just sprinkle it around, mix with soil, and water your flowers frequently.

After 6 months, you will repeat the process. The plants will absorb the nutrients slowly. This way, you will not have to spend too much time fertilizing plants regularly.

On the other hand, the fertilizer consisted of small solid balls of fertilizer that fed the plant and dissolved over time.

That small ball will no longer be solid but a plastic ball covered with fertilizer, causing me to concern. It would be wonderful if the manufacturer could change the material to something eco-friendly.


  • Excellent ratio of nutrients
  • Great nutrients
  • Simple and convenient to use
  • Apply once per 6 months


  • Not eco-friendly

What do you need to know in finding your best orchid fertilizer?

Choosing the wrong fertilizer could be overwhelming and cause damage to your plants. Here is the simple checklist to help you pick the best orchid fertilizer:

Fertilizer types

Orchid fertilizer comes in two main types: slow-release fertilizer and foliar fertilizer. The difference between them is in the application time.

The slow-release fertilizer only needs to be fed once per 3-6 months (depends on the product instruction). The nutrients will seep into the soil and plant’s root system gradually daily. It’s a great idea if you are too busy but still have a passion for planting orchids.

On the other hand, the foliar fertilizers provide nutrients for plants periodically, usually once a week. This option will be a suitable fertilizer for those who have more time to take care of their orchids.

Major Ingredients

During plant growth and development, NPK fertilization for ornamental plants is an indispensable process. NPK ingredients are the best fertilizer for orchids that contain the right amount of nutrients to care for plants.

NPK fertilizer includes three main substances: Nitrogen, Phosphorus, and Potassium – these are essential substances to help flowering plants.

  • Nitrogen: nourishes green leaves, is good for leaves, and promotes rapid growth.
  • Phosphorus: fertilizing with NPK for ornamental plants, flowers, and fruits to encourage root growth, blooms, and green leaves.
  • Potassium: essential substance for healthy roots and tubers, lack of Potassium results in yellow leaves, underdeveloped plants.

Secondary nutrients such as Ca, Mg, S are often used but not much in quantity. Moreover, this group is extremely important for each rooting process, flower germination, or producing self-protecting substances.

Orchid fertilizers should stay away from Urea sources. Soil species must first transform the Nitrogen availability in Urea into a plant-usable type, which is inefficient since orchids do not grow in the soil.

how to choose orchid fertilizer

Orchid stage of development

Orchid plants will go through 3 stages of development. These stages start with the development of stems, bud formation, and flowering. Depending on the specific stages, orchids may need different nutrients.

First stage- Leaf stem development

This stage occurs when the sprout is most developed until there are signs of standing at the top of this flower. The orchids need lots of Nitrogen at this point. As a result, slow-release fertilizer with a high Nitrogen content, such as 30-10-10, is highly advisable.

Second stage- Bud formation

This next stage is when orchids store nutrients and prepare to flower. Therefore, they need the full three types of NPK, especially the P content should be given the most priority. The ideal fertilizer for your orchids in this period is a balanced one, such as 20-20-20 or 14-14-14.

Third stage- Flowering

Orchids need a lot of K at this point. Therefore, high Potassium fertilizers should be prioritized.

Frequently Asked Questions

This portion demonstrates the list of common questions and answers around the best orchid fertilizer as a point of reference. It provides you with valuable knowledge about plant fertilization.

How to fertilize orchids?

Follow the product instruction on their label to get the most effective result. For example, a slow-release product like Osmocote Smart-Release Plant Food Plus Outdoor & Indoor recommends feeding your plants only once per 6 months with a certain dose.

Otherwise, once a week to two weeks, such as Miracle-Gro 100195 Ready-To-Use Orchid Plant Food Mist or EarthPods B079344QTQ Orchid Organic Plant Food Spikes.

When to fertilize orchids?

  • Early morning: low temperature, high humidity. When the sun rises about 9-10 hours, the temperature gradually increases, the humidity decreases.
  • Noon from 9-10 to 15-16 hours: high temperature and low temperature continuously for many hours.
  • In the afternoon from 15-16 hours: the temperature gradually decreases, but the humidity increases slowly until night.
  • During the night: the highest humidity, the lower temperature.

When should you not fertilize orchids?

Winter is the period that your orchids should receive the minimum or avoid fertilizer at all cost. The plant will reinforce its roots, cultivate leaves, and save energy for the next growth and flowering. It will rebloom every 8 months to 12 months on average.

How to know about Orchids’ symptoms of malnutrition?

  • Lack of nitrogen: The plant is stunted; the quantity of buds and leaves on the tree is limited; the leaf size is variable, gradually changing to yellow color from old leaves to young leaves.
  • Lack of phosphate: Plants are short, small, with underdeveloped roots. Young shoots are unable to grow, flowers slowly, and fruiting is reduced as a result of the dull green leaves with purple streaks on the leaf sheaths and leaf plates.
  • Potassium deficiency: Plants are underdeveloped, shortened in length, dwarf plants; leaf margins turn yellow and dry gradually; leaf tips are short; orchids are susceptible to pests and diseases; low fructification rate, and poor seed germination.
  • Lack of calcium: Underdeveloped roots, small leaves, weak plants, easy to fall.
  • Magnesium deficiency: The roots are large, but the leaves are small; old leaves transform silvery-white due to a lack of chlorophyll.
  • Lack of sulfur: Plants are barren; young leaves turn yellow; the plants are sick, languid.
  • Lack of zinc: The tips on the tops shorten; the leaf plates are narrow and pointed; the young leaves are staggered; the roots are underdeveloped.
  • Iron deficiency: The leaves are pale yellow to white silver and underdeveloped.
  • Lack of copper: White stains occur on the head and edge of the trees, and soft leaves eventually turn white green and dry. A lack of copper is often followed by many root buds, but young buds die slowly.
  • Lack of manganese: Young, green leaves look less shiny after successive yellow streaks appear along them.

Should you use an ice cube in watering?

The answer is no. In their natural habitat, orchids don’t experience freezing conditions or cold water.

Therefore, the ice is something that they have never encountered before and are not prepared to handle. Imagine you watering ice and touching orchids leaf; they will be damaged.


The best orchid fertilizer is an ideal solution for your flower care. It just feels so satisfying when watching your garden develop in the whole process, from a small plant to a gorgeous mature orchid with green leaf and colorful bloom.

To sum up, The 8303 Better Gro Orchid Food deserves to be on your shopping list. It is not only inexpensive, but it also provides the perfect NPK formula for keeping your plants healthy and beautiful. Your orchids will love it!

Nevertheless, Miracle-Gro 100195 Ready-To-Use Orchid Plant Food Mist is ranked as the runner-up in the race of the best orchid food owing to its fair price and effective job in nourishing your lovely plants.
