This product provides the crucial nutrients to increase the moisture level of your orchids. You are supposed to give your orchid more water than you thought.
The proper amount of water is so essential that it may impact on the process of photosynthesis either well or not.
Having absorbed the soil, water through roots goes to the leaves and generates oxygen and hydrogen. Then, the elements combine with carbon dioxide in the plant's cells to produce 'sugar' - the critical food to feed your plant.
If the plant is not hydrated enough, it breaks the instant plant growth and bloomings. That's why orchid lovers need to provide mist to their plants.
Only by spraying the mist directly on its leaves, stems, roots, and soil once per month, you will be amazed at how your orchid plant has sprouted new growth without being damaged or burned.

How To Choose The Best Orchid Fertilizer?
Before making the final purchase of the best orchid fertilizer, there are several factors that you need to bear in mind.
For those orchid lovers, the NPK ratio is too easy to identify each macro ingredient. Nitrogen enhances foliage and stem growth. Phosphorus promotes solid roots and instant blooms. And potassium aids to extend plant issues.
You can find a complete ratio which contains three macronutrients. Or, a balanced NPK means equal amounts of Nitrogen - Phosphorus - Potassium, for example, 10-10-10.
These elements are so important for orchid growth because the plant can not produce itself. We recommend you choose the product with much nitrogen to have a better result.
Types of Orchid Fertilizer
There are main types of orchid food, including concentrated formula, spray and stick.
First, the concentrated fertilizers, liquid or granules, are required to combine fertilizer and water according to a proper ratio before applying on the soil and roots.
In fact, orchids don’t need too much fertilization, so you can dilute the mixture to feed your plant to prevent over-fertilization.
Second, spray fertilizers are very easy, and safe for every part of your plant except the blooms.
Last, sticks are another type of orchid fertilizers that are slow-releasing, no measure and no messy.
The Speed of Releasing
There are some orchid fertilizers which are fast-acting within 3-4 days; otherwise, some have a slow-release formula. It depends on your demand and the state of the orchids.
Proper Time to Apply
For each period, you can choose the right fertilizer that is suitable for the plant growth. Please take note that we usually feed orchids much during the growth period, medium fertilization before blooming, and less in the rest period - after the orchid blooms.
The simple tip, we highly recommend, is to read carefully on the label to learn how to use it in a proper way.
