Here, you will get to see our choice of the best orchid fertilizers. Even more, you’ll find a guide on choosing the right fertilizer for orchids, including how and when to fertilize your orchids.

Factors To Look For When Buying The Best Orchid Fertilizer

Buying the best orchid fertilizer can be quite tricky. Simply because there are several products from different manufacturers currently flooding the market. To this end, it is crucial to know the factors to look out for when purchasing the right orchid fertilizer.

Factors such as essential nutrients, form, and solubility play critical roles in determining which orchid fertilizer stands out above the other. Here, you find a guide that will aid you in making the right buying choice.

1. The Essential Nutrients

Typically, a good orchid fertilizer must contain a relatively equal amount of some essential nutrients, such as phosphorus, nitrogen, and potassium. These details come with their respective ratios on the product’s label.

Additionally, other nutrients that make up the 16 essential nutrients needed by the orchids for a healthy and robust growth include oxygen, magnesium, and zinc. Also, there’s manganese, iron, chlorine, hydrogen, molybdenum, sulfur, calcium, carbon, not to mention copper.

You must ensure you always look out for these nutrients in a product before purchasing it.

2. Nitrogen Nutrient Source

While it is essential to look out for the vital nutrients, it is even more important to pay attention to the fertilizer’s nutrient source. Cheaper fertilizers tend to have urea nitrogen as their source. However, these types of fertilizers are not suitable for orchids grown in cold regions as they make your plants become more ammonium toxic.

On the other hand, products that have nitrogen or ammonium nitrate as their source offer better quality. Although they are costlier, they are capable of providing your orchids top-quality nutrients for improved growth and beautiful blooms.

3. Water Solubility

Water solubility is another vital factor to look for in the best orchid fertilizer. You must ensure that the product you buy is soluble in water as it allows the orchid to absorb all the essential nutrients the fertilizer offers.

Besides, if you intend to make use of self-watering equipment, this feature will come in handy. Also, this feature makes it possible for all nutrients to go directly into the soil provided they have dissolved completely.

4. Form

Orchid fertilizers come in several forms, although the soluble powder and liquid forms are the most suitable form. Even more, most orchid farmers prefer soluble powder form, and this is because they are cheaper.

However, both forms offer unique advantages. On the one hand, soluble powder forms come in pre-measured bags and are easy to mix. While on the other hand, concentrated liquids form are more convenient to use since they are self-watering equipment ready.

In all, irrespective of the form you choose, always ensure you consider the water solubility of the fertilizer.

When Is The Best Time To Feed Your Orchids?

There is no particular time to fertilize your orchid best as it depends on where it is in its blooming period. Here are a few periods you can feed your orchids.

1. Growing Period

It is essential always to ensure your orchids are fertilized during this period just before their blooming cycle. While some orchids bloom during the summer and spring, others bloom during winter. Even more, some bloom up two times in a year.

In the orchid’s growing period, it is ideal for fertilizing it weekly while observing a break after every three weeks. Since the orchid is about to sprout, it will require extra nutrients. Also, ensure you always moisten the soil with water each time you notice dryness.

However, this method only works with soluble powder and concentrated liquids. Follow the manufacturer’s instructions if you are making use of stick or spray fertilizers.

2. Dormant Period

The dormant period is that phase after blooming, where the orchid’s flower withers and falls off. During this phase, it is essential to fertilize the orchid frequently. The frequent fertilizing will help it to remain active, healthy, and produce beautiful blooms.

One key characteristic of blooms is that summer blooms require more fertilization than winter blooms, both in their dormant phase. Additionally, mornings are the best time to fertilize or water an orchid as the leaves get enough drying time in the sun.

How To Fertilize Orchids?

When it comes to how to fertilize orchids, there is no single method as it depends on the type of fertilizer.

With concentrated formula fertilizers that require mixing with water, you will need to apply it to the roots and soil of the orchid. You must, however, ensure you thoroughly dissolve and mix it in with the right quantity of water.

On the other hand, some fertilizers can be conveniently applied to the plant’s leaves. But make sure you follow the instructions on the label to prevent mold and fungus problems.

More so, spraying is another safe way of fertilizing your orchid except for the blooms. There are also slow-release fertilizer sticks that are inserted between the edge of the pot and the plants’ roots.

Since there are several options of orchid fertilizers in the market today, choosing the right orchid fertilizer can be a bit challenging. However, whether you are looking for a liquid concentrate, granules, or even a spray fertilizer, we have provided you with our top picks for the best orchid fertilizers available.
