Frequently asked questions

About Orchid fertilizer — click a question to see the answer.

How do I fertilize orchids?

To fertilize your orchids, I recommend using a liquid fertilizer specifically for orchids, diluted to half or a quarter of the recommended dose. I usually apply it during watering, alternating between watering with fertilizer and watering with plain water. This is a gentle method that avoids burning the sensitive roots of these plants.

Which fertilizer should I choose for orchids?

The choice of fertilizer depends on the stage of your orchid. For growth, a nitrogen-rich fertilizer is ideal. For flowering, I prefer a fertilizer with a higher ratio of phosphorus and potassium. What I often see is the use of balanced fertilizers (like 20-20-20) or orchid-specific fertilizers with ratios adapted to different phases. If you want to know more about fertilizer brands, I invite you to consult this article on Advanced Nutrients or this one on Plagron.

When should I fertilize orchids?

I recommend fertilizing your orchids primarily during their active growth period, which is generally in spring and summer. During flowering, I reduce the frequency or concentration of the fertilizer. In winter, when the plant is dormant, I stop fertilizing completely. This is a golden rule to avoid overfeeding the plant.

How do I know if my orchid needs fertilizer?

Several signs can indicate a need for fertilizer. If the leaves are pale, yellowish, or growth is slowed, this could be a sign of deficiency. Less abundant flowering or smaller flowers than usual can also be an alert. However, be careful not to confuse this with overwatering or too much light. Regular observation of your plant is key.

What mistakes should I avoid with orchid fertilizer?

The most common mistake is overdosing, which can burn the delicate roots of the orchid. I always advise underdosing rather than overdosing. Also, avoid fertilizing a stressed, diseased, or dormant orchid. Never apply fertilizer to dry substrate; always water beforehand. Finally, do not use non-orchid-specific fertilizers, as their needs are particular.

What is the purpose of special orchid fertilizer?

Special orchid fertilizer is formulated to precisely meet the unique nutritional needs of these epiphytic plants. It contains a specific balance of macro and micro-elements, often at lower concentrations than conventional fertilizers, to prevent root burn. It promotes healthy growth, lush foliage, and, most importantly, abundant and long-lasting flowering.

How do I dose orchid fertilizer?

I always recommend following the manufacturer's instructions, but generally, I halve or even quarter the indicated dose. Orchids are sensitive and prefer low but regular applications. For example, if the manufacturer indicates 1 ml per liter, I would start with 0.25 to 0.5 ml per liter. This is a safer approach to avoid any risk of burning.
