Let’s dive into the world of orchid fertilization so your plants can bloom beautifully all year long!

🌱 Why Is Fertilizing Orchids So Important?

Most orchids are epiphytes, meaning they grow naturally on tree trunks, drawing nutrients from fallen leaves, dust, and rain.When grown in pots, they lose this natural nutrient source and rely entirely on the grower.

Without proper fertilization:

• Leaves turn yellowish or dull

• Roots lose strength

• Flowering is delayed or doesn’t happen

With proper fertilization:

• Green, firm leaves

• Strong, healthy roots

• More flower spikes

• Vibrant, long-lasting blooms

👉 In short: no fertilizer, no flowers.

🌸 Types of Orchid Fertilizers

🌿 Organic Fertilizers

Made from natural materials that release nutrients gradually.Examples: Bokashi, worm humus, bone meal, castor cake, and Vila Verde Bio Sachet.

Advantages:

• Improve the health of the substrate

• Provide balanced nutrient release

• Sustainable and safe to use

Disadvantages:

• May have an odor

• Require time to decompose

💧 Chemical (Mineral) Fertilizers

Industrial formulations with precise nutrient ratios (NPK).Examples: NPK 20-20-20, 10-30-20.

Advantages:

• Fast-acting

• Easy to measure and apply

Disadvantages:

• Risk of root burn if overused

• Do not improve the soil microbiome

🌿 Foliar Fertilizers

Sprayed directly onto the leaves, absorbed quickly by the plant.Examples: Liquid soluble fertilizers.

Advantages:

• Rapid absorption

• Excellent for correcting specific deficiencies

Disadvantages:

• Short-term effect

• Need frequent reapplication

🕓 Slow-Release Fertilizers

Release nutrients over several weeks or months.Example: Vila Verde Bio Sachet — lasts up to 6 months.

Advantages:

• Very practical (no need to fertilize weekly)

• Safe (prevents over-fertilization)

• Eco-friendly (biodegradable sachet)

🌼 Fertilization Frequency for Orchids

The ideal schedule depends on the plant’s phase:

• Growth phase (leaves and roots): fertilizers rich in nitrogen (N)

• Pre-flowering phase: fertilizers rich in phosphorus (P) and potassium (K)

• Maintenance phase: balanced fertilization every 15 days (for soluble products)

• With Bio Sachet: replace every 6 months

📌 Golden rule: it’s better to fertilize lightly and consistently than too much at once.
