Orchid Nerd Nutricote 13-11-11 All Purpose Slow Time Release Fertilizer (15 oz)
180-Day Controlled Release Feed for Orchids and More

Orchid Nerd Nutricote 13-11-11 All Purpose Fertilizer takes the guesswork out of feeding your orchids and houseplants. This slow-release formula gives your plants a balanced mix of nutrients over 180 days, helping them grow strong roots, healthy leaves, and beautiful blooms—with no need for constant feeding or worrying about overdoing it.

Each tiny pellet (called a "prill") contains everything your plant needs—nitrogen, phosphorus, potassium, and important micronutrients—all wrapped in a special coating that controls how fast the food is released. The warmer it gets, the more your plants grow—and the more nutrients they receive. That’s smart feeding that keeps up with nature.

Perfect for orchids, bromeliads, houseplants, garden beds, and nursery plants.

Why Growers Trust It:

Orchid Nerd Nutricote 13-11-11 is trusted because it works reliably every time. It releases nutrients steadily, doesn’t burn roots, and avoids those nutrient spikes that other fertilizers can cause. The special coating breaks down based on temperature—not soil moisture—so your plants get just the right amount of food, when they need it. It’s clean, safe, long-lasting, and makes fertilizing easy for everyone—from greenhouse growers to weekend plant lovers.

Just sprinkle 2–3 teaspoons on top of the potting mix in a 6" pot.

Recommended Pairings

• K-Lite Fertilizer Formula 12-1-1 (10% Ca, 3% Mg) – 8 oz: Extra calcium and magnesium support for orchids in bloom.
• 11-2-12 Slow Time Release Fertilizer (120 Day) – 16 oz: Use for shorter growth cycles or alternate with 13-11-11.

Tips for Best Results:

• Apply after repotting or when new growth begins for maximum absorption.

• Avoid placing pellets directly on plant crowns to prevent rot.

• Store unused fertilizer in a cool, dry place—heat or moisture can start the release process early.

• Mix lightly into media if using bark-based orchid mixes to anchor pellets and slow breakdown.

• Use with clean, pasteurized potting mixes for best nutrient control and to avoid microbial interference.

• Monitor plant response—leaf color, root health, and flowering patterns will help you fine-tune reapplication timing.
