8 Best Orchid Fertilizer + When To Use Orchid Food

Orchids, flowers famed for their beauty and diversity in colors and shapes and sizes. Orchids belong to the largest family of flowering plants in the world which boasts over 28000 known species. They are also notoriously difficult to grow and are quite complex in terms of how they need to be nurtured in order to thrive.

In the wild, orchids have access to the proper conditions and nutrients that they receive from bark, rotting leaves, fungi, lichen, rainwater and even from bird droppings. However, creating the same conditions in your home is a completely different story. 

Taking good care of your orchid, whether in a garden or inside your home, does not stop at watering- you have to feed them too. Their food consists of fertilizers, which needs to be fed to the orchids in a proper manner with the correct types of fertilizers.

Navigating the world of fertilizers can be tricky as there is a lot of science behind it and there are also so many fertilizers on the market. What’s more is that choosing the wrong fertilizers could cause damage to your plant.

This guide has been put together taking into consideration the best fertilizers out there and also gives you more information about how and when to fertilize them to ensure that you maintain a healthy plant for a long time to come.

Fertilizer Facts

What is a Fertilizer?

First thing is first, fertilizer is a chemical or natural substance that is added to the soil to optimize soil health so that the plant can take up all the nutrients it requires to grow and thrive. Fertilizers are generally made up of three elemental nutrients essential for plant growth.

These nutrients are nitrogen (N), phosphorous (P) and potassium (K) and are combined in specific ratios depending on the needs of the plants. 

Different Types of Fertilizer

There are two main types of fertilizers that can be used for orchids. These are your slow-release (or spike fertilizers) and your foliar fertilizer. A slow-release fertilizer only needs to be applied or fed to the orchid once every two to nine months, depending on the product.

The nutrients will seep into the soil and the root system gradually on a daily basis. The slow release fertilizer type is beneficial if you lead a busy lifestyle but are still passionate about orchids and their care. Whereas, foliar fertilizers need to be applied or fed to the plants on a regular basis- usually once a week or so.

This option of fertilizer is optimal if you have more hand-on time to take care of your plants.

The fertilizer types also come in different formats. The most popular types of fertilizer formats are concentrated liquid fertilizer or water-soluble granules that can be added to water and dissolved to form a solution. Adding of the foods to water is valuable and a time saver, as this means you can water and feed your plants at the same time. 

What Nutrients Do Orchids Need?

For orchids to produce their beautiful flowers and luscious green foliage, they require 13 nutrients in  total, three of which are nitrogen, phosphorous and potassium or NPK. Nitrogen is important for the rapid growth of plants and is an essential element to nourish the leaves and to ensure that the leaves maintain a good health and color.

Phosphorous  encourages the growth of  healthy and robust roots and ensures optimal bud and fruit development over time. Lastly, potassium is an essential substance for bulbs and tubers and used as a defense against the environmental changes that are bound to occur in a plant’s life, such as  pests and climate changes.

Potassium is also critical in preventing yellow leaves and underdeveloped or stunted plants. Other elemental minerals such as calcium, magnesium and sulfur are also significant in maintaining good plant health, but in fertilizer mixes, they are used in smaller quantities.

However, they assist with the rooting process, flower germination and production of defense substances, as well as assistance with essential processes like cell division and respiration. 

It is important to note that for orchids, fertilizers containing urea sources are not optimal to use. This is because the soil microorganisms must first transform the Nitrogen available in the urea into a substrate that is more available for uptake for a plant and this makes for an inefficient and ineffective process as orchids, generally, are not housed or rooted in the soil.  

On the other hand, a good orchid fertilizer contains a 20-20-20 ratio of nitrogen, phosphorus and potassium. This ratio provides a good balance of nutrients for terrestrial orchids. However, if you are growing your orchids in a medium that isn’t soil, you should opt for a higher nitrogen concentration in the fertilizer mix. This is because these epiphytic orchids are grown in a non-soil based medium like bark, which naturally has a lower nitrogen content than soil does. 

Another thing to consider when buying a fertilizer is the stage of development your orchid is in because it is going to need a different cocktail of nutrients depending on where it is at in its life cycle. 

Stages of Development

Orchids go through three stages of development. These stages begin with the development of stems, followed by the formation of buds and then flowering. 

First Stage- Leaf Stem Development

This stage occurs when the sprout is at its most developed and continues until there are signs of a bud starting to form at the tip of its leaves. During this stage, the orchid requires lots of Nitrogen to nourish the leaves and for rapid growth. 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. They therefore require all three elemental minerals, with special emphasis on phosphorous in some cases. Ideally, at this stage, the fertilizer ratio of NPK for your orchids in this period is a balanced one, such as 20-20-20 or 14-14-14.

Third Stage- Flowering

Potassium is used a lot in this stage, and so it should be prioritized when choosing a fertilizer.

Frequency of Feeding

This depends on the type of fertilizer used, but expert growers usually select a foliar fertilizer to use and feed the orchids on a weekly basis with a weaker solution of fertilizer. It has been demonstrated that doing this, feeding more often with diluted fertilizer will result in more optimal orchid growth and health over time than when fertilizing at a higher concentration, less often. 

Orchids need to be fed during their stages of growth like mentioned above, and it is important to remember that orchids go dormant in the winter and so should only be fed in the spring again. It is also crucial to remember to not feed sick plants when they are weak as this puts more strain on them, and they should conversely not be overfed.

You know they have been overfed when their leaves are very dark and floppy. Overfeeding them will force them to grow too fast, making them more susceptible to disease over time.

How to Spot Nutrient Deficiencies

If a plant lacks nitrogen, the plant will be stunted and the quantity of buds and leaves on the plant is limited. A lack of phosphate means that the plants are short and small and will have underdeveloped roots and young shoots are unable to grow, and the plants will flower slowly.

Likewise, a potassium deficiency is indicated by underdeveloped and dwarfed plants that will be susceptible to disease and pests. Other deficiencies like calcium, magnesium and sulfur are characterized by weak plants, large roots and barren plants with yellow leaves, respectively. 

Deficiencies in zinc, iron, copper and manganese are characterized by pointy leaves, yellow and white leaves, and young leaves will appear to have yellow streaks on them, respectively.

As this is a granular product, the granules need to be dissolved in water and then applied to the orchid on a monthly basis throughout the growing season.  The granules are easy to dilute and make application of the fertilizer easy. Again, it is best to stick to the manufacturer’s recommended instructions on application to ensure no damage is incurred on the plant or the blooms.

Grow More Urea Free Orchid Fertilizer 

Grow More 7517 Urea Free Orchid 20-10-20 Fertilizer, 3-Pound

Nutrient ratio: 20 – 10 – 20 N-P-K

High in potassium and nitrogen, the Grow More Urea Free Orchid Fertilizer will get to work straight away and encourage the rapid growth and development of foliage and blooms in your orchids. The blooms that are grown are vibrant and big. The biggest advantage of this product is that it is free from urea.

Urea is usually a good source of nitrogen for most plants grown in soil, where the microorganisms can convert nitrogen into nitrates and nitrites, which plans can take up easily. Urea it is really inefficient to use for epiphytic orchids as these do not have the microbes which are able to facilitate the conversion and therefore does not get taken up or absorbed by the epiphytic plants.   

The granules of this product are water-soluble and dissolve really quickly and easily in water. The orchids can then be fertilized weekly with a solution of 1 teaspoon of granules for a gallon of water. For epiphytic orchids, it is a good idea to soak the growth medium with the solution and let it drain before placing the orchid pack into the pot.

This is handy as you can water and feed simultaneously and do not have to worry about watering in between feeds. Although, you may want to use one week of the month for just a plain or regular water. Be careful to follow the manufacturer’s instructions, as if you over use it, it may have harsh and damaging effects on the plant.

When testing this product, we loved that it gets to work straight away and that it is free from urea.
