7 Best Fertilizers for Orchids

best fertilizers for orchids

Owl, Bee, Vanilla flavor, monkey, and a naked guy. Can you figure out the commonality amongst all these? These all are the types of orchids that are found all around the world. Having introduced in 1845, the name ‘Orchid’ has derived from Orchidaceae. Ranging from the size of a small coin to the size that can weigh up to a hundred pounds.

Additionally, some orchids have an age of more than a hundred years. The flowers that the plants bore can survive up to six months once bloomed. They are also one of the oldest species of flowering plants that ever existed. This flower is also the one used for purposes such as making spices, perfumes, and Asian medicines.

Having existed for approximately a hundred billion years, these plants and flowers still need protection. Not only that, just like other plant species, they also require fertilizers to survive healthily in today’s world. The best part about these, they are easy to handle, require the least care, and are beautiful as well.

What is the General Care that is required?

Orchids require just the exact amount of indirect sunlight as well as water. Too much of the sun can lead to scorching of the leaves. Brown leaves are an indication of the need for less light. Green leaves are an indication of the need for more light. Too much water can also lead to a damaged plant. Where some plants need water every four to five days, others require it only once a week.

 With this, Orchids also require a favorable temperature for them to grow indoors. Like deserts, Orchids require cooler temperatures at night to bloom properly. Lastly, the thing that is needed by any and all species, fertilizers also play an important role.

Fertilizers can be fed weekly or monthly. However, if chosen weekly, it should be given as diluted. Flowers or no flowers, fertilizing is still important for the plant to stay healthy in all conditions.

How to water Orchids properly?

The first step for watering Orchids is to find a proper and suitable pot. A pot with sufficient holes in it to allow the water to pass through easily. It is very important for the water to drain out of the plant. Otherwise, it can lead to swollen nodes of the plants, causing more damage.

You can choose whatever way and however you want to water your orchid. However, the best way to do that is by keeping the orchid under running water. Running the orchid in a room temperature water faucet allows the water to seep in properly. This helps the water to reach every part of the soil properly, as well as drain out from the holes.

It further helps in keeping the soil and the nodes from having residues of water in them. An indication of watering the plant again can be taken by the weight of the plant. Whenever it becomes lighter than before, it is time to water your plant again.

The plant is advised to be watered in the morning or afternoon. This gives the water plenty of time to evaporate before the night. If the water stays in the plant overnight, the plant becomes prone to diseases. It is also advised to clean the water droplets from over the leaves to prevent rotting of the same.

Feeding the Orchids properly and sufficiently

Feeding the Orchids simply means fertilizing them. Orchids should be fertilized monthly; however, very little should be used. They are only fed weakly by experts, and that too very little. For this, a ratio of 20-20-20 in the NPK format.

NPK stands for Nitrogen, Phosphorus, and Potassium. Just as water and sunlight intake should be just sufficient for the plant, the same is with fertilizers. Fertilizers should be given slightly less than required only.

There is also a time when these plants go to sleep, that is, go in a dormant state. As understandable as it already is, no one eats or should be fed while they are asleep. Even if it is a flowering plant such as the Orchid. Just like humans are hungry when they get up in the morning and have breakfast, it’s a similar case with these orchids. It’s best to feed them when they come out of their dormant state. 

Essential Nutrient Requirements

As mentioned above, the essential nutrients required are Nitrogen, Phosphorus, and Potassium. They are also referred to as NPK content in fertilizers. One thing that has to be taken care of is that the nitrogen isn’t urea nitrogen.

Amino acids as well as vitamins were first used to fertilize these plants, including nitrogen. This is why fertilizers now have the three main essential nutrients in them. Nitrogen (N) is required for proper growth of the leaves as well as luscious green color. Phosphorus (P) is needed for enhances the growth of the roots and proper blooming of the flowers. Potassium (K) is used as a supportive nutrient for the plant to grow healthy overall.

When to fertilize the Orchids?

There is a general rule to fertilize orchids by beginners every once a month. Experts can do the same once every week.

Additionally, it is best to feed the plant majorly in the time of peak growth. At this time, it is best to feed the plant once every two weeks, in a month. The most suitable time to do this is in summer and in spring. In these two seasons, the Orchids are in the stage of full growth.

During the other two seasons, the Orchids are in a dormant stage. This means that they are asleep. At this time, they should be fed only once a month.

How to fertilize Orchids?

As mentioned above, Orchids should be fertilized monthly, with very little use of fertilizers. However, they can also be fertilized weakly in the case of some of the species of the plant. Fertilizing the Orchids weakly is and should be done by experts only.

The best time for an orchid plant to be fed is when the blooms have dropped. That is the time when the plant required its essential nutrients the most, i.e., NPK.

Steps to fertilize an Orchid plant:

  1. Choosing the most suitable fertilizer for your plant. Look for the fertilizer that has a ratio of 20-20-20 of the NPK.  It is often mentioned at the label itself about the nutrient content of the fertilizer. Half the strength of the fertilizer should be used with an equal amount of water to fertilize the plant.
  2. Using a narrow pitcher, the fertilizer should be poured into the soil. A precaution that has to be taken is to keep the leaves away from the fertilizer. The leaves should not come in contact with it.
  3. It is essential to keep the plant in a pot with holes underneath. In this case, it is essential for the excess fertilizer solution to be drained out of the plant.
  4. Another precaution that is necessary is that the plant should not be watered on the days of fertilizing it. 
  5. This process should be repeated once or twice a month in the case of beginners.

How often should the Orchid be fertilized?

The owners of the plants tend to fertilize the plant more and more. In order to have a healthy plant growing, fertilizers are used often as well.

The basic and the most important rule to grow Orchids is to water and fertilize them carefully. Most experts, as well as the fertilizing companies, recommend its usage once a month. Using less of it may result in lesser or restricted growth of the plant.

The blooming of the flowers can also be hurdled if used less. Using more of it may result in the roots to burn. It may also result in the restriction of the blooming of flowers as well. 

What kind of fertilizer should be used for healthy growth?

Fertilizers of two kinds can be used to feed the orchids: natural ones and artificial ones. Natural fertilizers are the ones that are available at home. Artificial fertilizers are the commercial ones available in outdoor shops.

Natural fertilizers may include Eggshells, milk, buttermilk, potatoes, rice water, tea, etc.

  1. Eggshells have calcium and potassium in them, which are the necessities of the orchid plant. Eggshells are crushed into small pieces and put on the plant bark. This helps the plant to absorb the nutrients off the shells. The shells can also be boiled and then put up on the bark.
  2. Milk or buttermilk: Both are rich in nitrogen, which is again a needed nutrient. This is something that is easily available and can be used to fertilize as well.
  3. Potatoes: Potassium and phosphorus are the nutrients available in a potato. Both these nutrients are the mainly needed ones for the plant. These, too, can be boiled. Then they can be put in the bark of the plant for it to absorb in itself.
  4. Rice water: Rice water is rich in many of the vitamins which are necessary for Orchids. Vitamins also help them grow healthily. Vitamins such as thiamine, folic acid, riboflavin, and niacin are available in the water. Rice water obtained from brown rice is most beneficial than the water obtained from white rice. Moreover, this is also something that is easily available. It is also cheap and can be made at home itself.
  5. Tea: Not just tea but tea bags are specifically beneficial for Orchids as fertilizers. Tea and tea bags are high in nitrogen. It is, as mentioned before, a necessary need for the plant. Tea bags are preferred more in the case of Orchids. The contents inside the bag can be emptied out and put in the Orchid pot. Being high in nitrogen, the nutrient can then easily be absorbed by the plant from the teabag contents.

Commercial fertilizers are the ones available at any shop outdoor. The only thing to take into consideration while choosing the best fertilizer is the NPK content in them. The best ratio required in one is 20-20-20, which is also written on the front label of the fertilizers. The other ratio that can be worked with is 10-10-10. The lesser or, the more diluted fertilizer used, the better for the plant.
