How to Choose the Best Orchid Fertilizer?
Choosing the best orchid food for flowering is not so difficult if you consider some points. Here I will discuss some points that you should strictly consider before buying.
Type of Orchid Fertilizer
Different types of orchid fertilizers available in the market today. Such as Water-soluble, Granular, Spike, Liquid, and Capsule.
Which type of fertilizer should you pick for your orchids?
Honestly, all are good for orchids. But they are different in the application method. Water-soluble and liquid fertilizer need to be pre-measured and premixed with water before application. In contrast, water-insoluble granular and spike fertilizer don’t need to be pre-mixed.
Nutrients and Their Ratio
Like all the other plants, orchids need balanced nutrients for thriving and blooming. Let’s first talk about NPK-
NPK means the ratio of nitrogen, phosphorus, and potassium. These are the three primary nutrients. Nitrogen important for green foliage, phosphorus for blooms, roots, and potassium for overall plant health. Only the balanced ratio can give you healthy green plants and colorful blooms.
Moreover, some other essential nutrients such as iron, calcium, magnesium, zinc, etc are important for long-lasting blooms and protect the plant from chlorosis and some other diseases.
Remember one thing; the fertilizer must have a lower amount of urea nitrogen. Excess urea nitrogen may burn the orchid leaves.
Organic vs Inorganic
Organic and inorganic both are good for orchids if they don’t contain any harsh chemicals. Some reputable brands like Miracle-Gro have been producing synthetic fertilizer successfully. Plants and gardeners both like those fertilizers. Don’t think I am promoting synthetic fertilizer. I am only telling you the truth.
You can also pick organic and natural fertilizer from reputable brands like Espoma, Aquatic Arts. The best thing about organic fertilizers is they contain some beneficial soil microbes.
How Often to Fertilize Orchids?
Fertilizing schedules may vary depending on the type of orchid fertilizer and ratio of NPK.
Generally, water-soluble fertilizer needs to apply once per 1-2 weeks but you can apply slow-release fertilizer once per 1-2 months.
Feeding once per week is the basic rule of fertilizing. But the best way to know how often you should feed your orchids, read the label of your fertilizer.
Quick Tips: If you feed your orchids every week, avoid feeding every third week. It minimizes the chance of overfeeding.
When is the Best Time to Fertilize Orchids?
Orchids need more fertilizer in active growing seasons. After blooming they don’t need too much fertilizer. So apply fertilizer once per 1-2 weeks in an active growth period and apply once 3-4 weeks in the rest of the period. And stop feeding when the blooms fall off and orchid goes dormant.
