The Best Fertilizer For Orchids – Colorful, Beautiful Flowers

June 5, 2022 by JoJo Leave a Comment

Fertilizing orchids is important for successful plant growth and blooms.

Unlike most plants that absorb nutrients from the soil surrounding their roots, orchids naturally live on trees, trapping material and soil particles blown through the air. This material is then absorbed through their roots.

When they are not in their natural environment, it is important to provide the nutrients the plants need. This means feeding the appropriate fertilizer, in the right amount, at the correct time.

In this post, we are going to consider what to look for in an orchid fertilizer and a few of our favorite options.

What is the best fertilizer for orchids?

The quick answer is that orchids require a well-balanced fertilizer. What that means is an equal amount of the three main nutrients: nitrogen, phosphorus, and potassium. A good target to aim for would be plant food that has an NPK Ratio of 20-20-20.

Here is a quick preview of our top 5 options

  • Miracle-Gro Orchid Food
  • Schultz Water Soluble Orchid Food
  • TeaDrops Liquid Plant Food & Flower Fertilizer Tea Packets
  • Jack’s Classic 20-20-20 All-Purpose
  • Schultz All Purpose 10-15-10 Plant Food Plus

More about each fertilizer in a moment, let’s now talk about what to look for in the best orchid fertilizer.

What to look for in an orchid fertilizer

A well-balanced fertilizer, such as a 20-20-20 is the best option for indoor orchids.

These numbers found on a container/bag of fertilizer are the N-P-K ratio; this ratio lets the consumer know the percentage, by weight, of nutrients in the bag.

In this formula, a 10-pound bag of fertilizer would contain the following: 2 pounds of nitrogen, 2 pounds of phosphorus, and 2 pounds of potassium.

A balanced fertilizer like 20-20-20 would ensure the orchid plant is receiving similar amounts of nitrogen, phosphorus, and potassium and all of the other trace elements necessary for plant growth.

Nitrogen is one of the key nutrients needed for plant growth with its main responsibility being vegetative growth. It is assimilated in the plant into amino acids which are the building blocks for protein; it is a major component of chlorophyll and helps to make the foliage green, and nitrogen is necessary for many enzymatic reactions within the plant.

Phosphorus is a component in DNA and RNA (the genetic building blocks within plant cells) and is needed for root growth and flowering.

Potassium works more indirectly than the other two nutrients. It is not a component of any plant parts but activates many of the enzymatic reactions that occur within the plant, making it imperative for overall plant health.

When it comes to choosing fertilizers, the market is flooded with various options: orchid specific food, all-purpose fertilizer, synthetic plant food, organic products, granular and liquid fertilizers (to name a few).

This abundance of options allows consumer preference to weigh heavily when picking a plant food to fertilize their indoor orchid plants.

Are Coffee Grounds Good For Orchids?

Yes, coffee grounds are good for orchids. Not only are they a good source of nitrogen, but they can also aid in repelling bugs such as snails. You can either apply it directly to the soil or compost it first.

It is important to note that fresh coffee is acidic and will affect the pH level of your soil. For that reason when using them for orchids be sure to use coffee grounds that have been used rather than fresh grounds.

Who knew drinking a cup of coffee could result in beautiful orchids in your garden?

Are Eggshells Good For Orchids?

Yes, eggshells are good for orchids. Many gardeners don’t know that eggshells can be a great source of calcium and potassium. Nutrients that will make your plants thrive.

Simply save your eggshells from breakfast, break them up into small pieces and spread them along the base of your plant.

Is Miracle-Gro Good For Orchids?

Yes, Miracle-Gro is great for Orchids. One that we really like is Miracle-Gro’s Orchid Food. This is a water-soluble plant food with an NPK of 30-10-30. In addition, as most products by Miracle-Gro, it is extremely easy to use.

Can I use rose fertilizer for my orchids?

No, I would not recommend using rose fertilizer to feed your orchids. Orchids need a well-balanced meal with a nutrient ratio of 20-20-20. A high amount of these nutrients is needed to be both healthy and to be able to produce colorful flowers.

Plant food that is designed for roses usually has a much lower nutrient ratio and thus wouldn’t be the best choice. I personally would try an all-purpose option before turning to a rose fertilizer.

Final Thoughts…

The thought of growing orchids at home can be intimidating to many people. If the appropriate variety is chosen for the intended environment, and some proper care given to the plant, it is possible for the average homeowner to grow beautiful orchids.

Applying one of the fertilizers listed above will help to ensure plants look their best and produce beautiful blooms to enjoy.
